This is my latest project. I’m transplanting a ’94 Ford 460 with a ZF 5 speed into my ’58 Chevy truck. Why a Ford into a Chevy? I have 2 complete engines and transmissions with computers and harnesses, so the expense is minimal. The truck in the pictures is a donor from the local junk yard that I picked up for this project. Getting the engine settled in there was the first challenge, it’s real tight against the steering box. The second was getting the cuts and fit-ups of the channel. Some of it was a little sloppy so I compensated with more weld passes.I made the cross-member in 3 sections so I can easily remove it from the donor and move it to my truck. It will get bolted into the truck with three ½” bolts across the tops and two 7/16” bolts on the bottom channel sections. Plus having the center piece removable allows me to easily drop the oil pan every 50K miles to replace the inevitable rear main seal leak.The transmission cross-member is next. Let me know what you think… good and bad. Attached Images

Reply:Thanks for all the positive comments. This is mainly a project for fun. My truck currently has a '73 350 in it with the original '58 4 speed behind it. It runs fine for what it is, but the truck is a medium duty that weighs 9K lbs empty so it will benefit greatly from the swap. I also plan to upgrade the brakes from the single cylinder master mounted under the truck to a dual that mounts on the firewall. I have the brake/clutch assembly from one of the trucks the engines came from, so this donor will be used to fab up that upgrade too. Plus in the process of the engine swap I'll be switching from the mechanical clutch mechanism to the hydraulic from the Ford. I'll keep posting my progress as I move along. The next challenge is a radiator/fan combo. The 460 is a surprisingly wide and long engine in these old trucks.Here's a couple pics of the Donor. I took only what I needed for this project. It rides on a set of Albion casters in the front for tight turning and a pair of genuine Goodyears in the back for traction. That was a fun day in "the yard" with the cordless recipricating saw  Attached Images
Reply:I havnt seen an all metal dashboard like the one in your donor truck for a while.  Nowadays, dashboards are all plastic with fake metal or fake wood but then everyone knows that.I saw a Ford transplanted into a chevy down in LA years ago. Its kind of perverse but I guess its better than an ISUZU in a Chevy.

Reply:Ahhh that's nuttin.  I have a 94 GMC 3500 with a 6.5 TD auto FWD.  I bought it new and it still has only 120K miles on it and it runs like a top.  The body however leaves something to be desired.  I have been eye-balling a CJ5 Jeep down the street with a blown engine and perfect body.  That looks to be a tight fit.
Reply:Ok, I've reached one of those moments where I spend more time looking at a problem than just making a decision and going with it. I know I'm over thinking the problem which probably isn't a problem at all! The best solution is to stop thinking about it and just do something I'm trying to decide how to bring the driver side section of the transmission crossmember over to the frame. The limiting parameter is the transmission will ride close to the floor of the cab, which means there's not enough clearance to lift the end of the tranny in and out of the crossmember; therefore the crossmember must be able to be put in place after the transmission is in it's location. I made the passenger side to go upward and sit on the lower frame rail section. This was an easy decision becasue there's a PTO driveshaft running down that side which is represented by the 3/4" EMT pipe.So given the way the pasenger side is built I'm looking at 2 options for the drivers side:1. Run the 3 inch channel straight over to the underside of the frame rail which will get bolted up to the bottom and allow the crossmember to be removed easily from under the transmission2. Build the drivers side as a seperate peice that will bolt to the peice I already built and run it upward over the drivers side frame rail.Obviously option 1 is the quickest and easiest solution. The reason I'm struggling is I'm also trying to figure out the best location for the exhaust pipe. Option 1 will work fine if I run the factory exhaust manifolds; I'll be able to easily bend and run the pipe up over the tranny crossmember. If I run a set of headers then option 1 might be in the way and it might work best to run the crossmember higher.This dilema is probably best solved by finding out the cost of custom headers, which is the only solution for putting a set of headers on this engine in this frame. If the price is ridiculously high, then it's manifolds and option 1. The only hesitation with the manifolds is they break the bolts in the heads often, usually by the third engine start Anyone have an idea for the average cost of custom headers? Attached Images
Reply:I got over myself and decided the problem was only a perceieved problem. I'll have plenty of room for exhaust pipe reguardless of which way I go so i decided to finish it up in the simplest way. I "piggy backed" a peice of 3 inch channel and used a 2x2x1/4 angle on the end to bolt up to the frame. Here's the reults. Attached Images

Reply:Well... here we are a year later and still at square one I did myself a favor and bought a good running F350 with a 460 5 speed and decided it's not the drivetrain of choice for my swap. No top end and eats fuel at a phenominal rate! I did alot more reading and found other issues that the mid 90's 460s suffer and decided to go a different route.Diesel I did some "horse trading" with all the 460 stuff I collected and picked up a 97 F250 with the 7.3 turbo and 5 speed. So here we go for round two. So far, despite what I thought, the deisel is much easier to fit in there. I do need to notch and box a small section of the original crossmember to allow space for the front of the oil pan, but that's the only mod to the chassis.I cut the crossmember out of the F250 and cut it down the center and gusseted it back together to fit snug into the Chevy frame.

Reply:I have a dream!!! I collect Case farm tractors and I want to put a case 504ci turbo engine in a ford some day, if it will fit under the hood. Maybe a 79 f350.

Reply:A smidge of progress... I may actually do it this time around After much adjusting, realigning and rebuilding 2 times I have the pedal assembly built and installed. The only thing I'm not pleased with is having to divorce the booster rod from the brake pedal but there's no other way to do it; so to compensate I went overkill on the material thicknesses. The pedal box is all 3/16 plate, the tube the brake pedal parts attach to is also 3/16 wall and the components that make up the brake pedal levers is 5/16. I "sistered" another lever along side the brake pedal, welding it to the tube and the original booster rod pin and made 2 levers to push the booster rod.Opinions? Attached Images

Reply:Nice truck Geezer. Looks like a 59 Apache 10 ?? The small block will fit in there easily. I have a 350 in my truck now, soon to be replaced by the 7.3. I presume you're going to upgrade the transmission too (700R4 maybe)? That's when you'll have to fab up crossmembers since these old trucks used the transmission mounts to hold the torque of the driveline versus motor mounts. I have the original 58 tranny behind the 350 so the engine mounts are the small pegs and rubber pucks that attach to the front face of the block.
Reply:Yup, good eyes 59 apache. First we are going to tidy up the body and get the 235 running with original tranny. We have a 350 and 400 sb, prior to v8 power I need to put a lift in the garage, sliding around on creepers is tuff. Will enjoy following your thread.

Reply:Here’s the latest update: Finishing up a box/bracket that holds all the electrical and electronics. I’m really happy with the way it turned out, considering there wasn’t much planning; rather I just started building and this is what I turned out. It mounts in the spot where the battery tray was and uses all four bolts that were for the tray. I built a water proof box for the PCM with a hole at the bottom that acts as both a breather and an outlet for the PCM chip cable. The back of the box (not installed yet) has a vent hole at the top with a hood to prevent water from entering. The IDM bolts to the box and the extended bracket holds the fuse box and engine harness connector. On top of the box I mounted the MAP sensor.Next up is building a tray to hold the 2 batteries. I’m planning to mount the batteries under the cab, on the passenger side. Rough measurements indicate they’ll fit. Attached Images
Reply:Got the down pipe made.... only took 3 trys  I'm an absolute novice at pipe work. I made a bracket to support the pipe from sway since it's being routed under the transmission to exit on the drivers side. I'll be bolting a PTO onto the transmission on the passenger side. The ends of the bracket are intentionally close to the bolts to allow some flexability in the rubber that connects them. Attached Images
Reply:Why the exhaust over to the drivers side?
Reply:I'll be mounting a PTO gear box on the transmission, passenger side. There's a long driveshaft that comes off the PTO and connects to a pump behind the cab. No room to run pipe and a muffler on the passenger side. This Pic shows the previous setup I had in the chassis, a gas 460, with the PTO and driveshaft (circled in red). Even with that setup (which never got further than where I am now) I would have still had to run the exhaust over to the drivers side.It's a short run from where I have the down pipe ended to where it will connect into the muffler. Just another 90 elbow to head rearward, 3 foot straight pipe and I'm connected to the muffler. The down pipe starts at the turbo as 3 inch pipe, then transistion into 3.5 inch at the elbow going under the transmission (elbow is 3.5 inch). I used the front section of the old cat converter for the 3 to 3.5 inch transition. Attached Images

Reply:Progress update and my findings on how to make it fit (long post):The 7.3L is a WIDE and TALL motor that completely fills the engine compartment on the mid 50’s Chevy trucks, but it does fit in there. The original engine cross member will need a couple modifications to allow clearance for the front of the oil pan and harmonic balancer, plus a couple other things. The cross member needs to stay since it’s a structural component of the frame.  See one of the pics on this post for the mods I did, they include: oil pan cut out, recess for harmonic balancer, cut out for the lower radiator hose and two cuts for radiator clearance.There’s little room for a radiator so I went the custom built route versus fooling around with the original radiator. The radiator I designed is 24” wide by 36” tall and drops below the original engine cross member where it can meet the lower radiator hose. At 24” wide it fits the original radiator support and uses the original 6 bolts for attachment.  The only modification needed on the radiator support (yet to be done) is cutting two small pieces from the top (one on each side) to allow space for the top tank. I’ll post more on this when I make this modification.The original transmission cross member needs to be removed and discarded and a new cross member made for the ZF5 or E4OD. I have some reservation with removing it since it’s clearly a structural component that connects the left/right frame rails at the spring perch mounts, but there’s no way to keep it in there. Making a replacement “bridge” isn’t practical because of the size of the new transmission. The new cross member will mount much more rearward, so it doesn’t really do the job of the original member. However, an additional cross member is being added for the engine, so it “somewhat” offsets the removal of the original transmission cross member.Depending on your steering setup (original box versus custom power steering) the engine will need to be placed about .75” off center to the passenger side. I’m keeping the original steering box, so I set the engine off center. If you’re working on a pickup chassis (I have a medium duty chassis) then you have several commercially available options for changing the steering and the suspension. In my case, I have none. If you remove the steering box and go with an “outboard box” then you can set the engine dead center. Also note, placing the engine off center gives room for the power steering box to clear the inner fender. Placing the engine dead center will require some “massaging” of the inner fender to make clearance.The other challenge with engine placement is leaving clearance at the firewall for the exhaust down pipe. I found a little firewall massaging with the 4lb hammer is required to “set” the clearance needed.  I went with a custom built down pipe, but I did try a commercially available pipe first and found it fits fine with the light firewall massaging. The good news is there’s plenty of room for the up pipes and turbo because of the deep recess already in the cab.Lastly, you will likely run into issues with clearance between the bottom of the oil pan (rear sump area) and the top of the axle. This is not an issue with the medium duty chassis since it sits very high compared to a pickup truck. If you’re working on a 4x4 truck and have it lifted then it won’t be an issue either, but if you’re working on a “slammed” 2wd you’ll have to convert the suspension to an A-frame style.More to come as I make progress and get past the next step.

Reply:Here are two pics showing how the lower radiator hose will work. The hose used is the original hose, just cut short at the coupler for the degauss bottle.  This made for an easy and somewhat elegant solution. Attached Images
