My 69 Mach has been down for about 6 months and finally got back together this last weekend. At the beginning of the year the project started with a simple TKO600 swap, the car already had a 4 speed in it so it was going to be a simple weekend swap. Once the motor was out it became apparent that the motor leaked oil from everywhere and since the motor had 2 cams go flat in its past I didn't need much more of a reason to pull it.
The motor was sent out for a refresh and a slight boost in power, I choose my engine builder based off recommendations and the fact that he had a dyno. I wanted the motor ready to drop in once I got it back with no leaks or surprises, and it was built by Advanced Engine in Salina Kansas the same place that built "Farm Trucks" motor from the street outlaw show. The car has AC and FiTech EFI, so my main goal was decent power and driveability as I have a 700rwhp Cobra to provide the real muscle.
The motor was able to stay . 030" over, forged pistons 10.5 to 1 compression
Custom Hydraulic Roller 224/232 on a 112LSA with the thought that I might go back with exhaust manifolds if it made enough power.
Stock 428 Cobra Jet heads rebuilt with new valves
Hooker Long Tube headers
Aluminum Ford PI intake
The motor made 408 hp with the long tubes at 5200rpms with 470ft of torque at about 3500rpm at 36 degrees of timing so the headers stayed lol. I told my dad that apparently the "good old days" weren't that good if thats all a 428 does lol.
I took the time while the motor was out to do some simple upgrades to the car. I pulled the carpet out and put two layers of the rubber backed aluminum sound deadener to the car, added extended seat rails to the drivers seat, repainted the engine bay, cut the front coil springs 3/4 of a coil, and ditched my inline electric fuel pump for a spectra in tank fuel pump. The seat rail extenders, and spectra tank were great upgrades for the money!
With the motor back I was able to go back to installing the transmission, I followed Ross's lead and tried to stab my motor complete with the transmission on and the Hooker LT's bolted to the engine already, I wish I could say it worked but after screwing around for a while I could see I'd have to remove at least 1 header. The transmission swap went well and I didn't have to cut any part of the car to make it work, which was nice.
You find a ton of info on TKO swaps in small block cars but not a lot of info on FE cars so here's my setup
428 with stock motor mounts and 1/8" motor mount spacers (to give the header flanges better clearance to the wrap around shock tower braces)
American Powertrain Streamlined tko600 with their adjustable shifter
Modern Driveline bell housing adapter plate
Modern Driveline crossmember
Hurst shifter handle #5380015
The transmission with a stock transmission mount definitely rocks the motor back more than stock. I installed a poly transmission mount that I had that was 5/16" taller than the stock rubber mount, I also slid a 1/8" spacer I had made in between the mount and the crossmember to further raise the transmission. I couldn't go anymore with out getting into the floor reinforcement bracket so I decided to try the car before I pulled the transmission and began to cut. The car drives well and has no vibrations or issues at 60mph, which I didn't want to go any faster than that with my 10+ yr old tires that I'll be replacing asap. The only complaint besides the TKO needing to be shifted to a forward gear before going to reverse is that the shifter handle that was recommended to me for this swap is too short. I ordered one thats a little longer and also comes back towards the rear of the car another couple of inches.
I drove the car about 35 miles yesterday and really enjoyed myself. Over the last year the car has received a refreshed motor with a slight bump in power, a custom auto sound slide bar radio, AC, FiTech EFI, and now overdrive. The car is actually fun to drive now, and I find myself getting excited over the thought of driving it. I'm so excited I just had to post lol, next on the list is the new tires, and a wash!
