Say FMX, I dont want to rain on your parade, but ! I had a 38 chevy coupe that I shoehorned a 454 into, first problem you have to route the headers out through the inner guards and down and out underneath the running boards to clearance where you will put the brake booster and the master cylinder under the floorboards. You may get away with the stock manifolds under there but it's a long shot. Good thing is that you will clear the steering box and theres plenty of room under the bonnet to keep the stock lines. I suppose you will run a TH 400 plenty of room in the chassis for that. I would recommend K bracing the chassis as the first time I revved my moter up it popped the doors open ! I hope all this helps and good luck with the project. That's a nice car with lots of potential S
