heres a question of huge power and prob a lot of work.......how impossible is it to place a 400 big block v8 into the escort engine bay? i had a guy from napa say it was possible with a lot of work. it sounds like it would add a lot of power.
anything is possible with money... and that would be a massive jobby, I hope you realize that this would cost upwards of 20000USD apart from the motor in hacking and welding the frame. Just make a tube frame VW sand rail or something: cheaper, faster, lighter, and alot less trouble. There are so many other engines that are available why would you want a chevy big block? Just get a bpt and rebuild it then turbo the hell out of it.
Also remember that V8s were built to run the rear wheels. So either you do a lot of work to make your scort rear drive or tone down the top of the V8 to make it fit under your hood. I believe it´s somewhat possible. I saw a Cavy w/ a 350 in it once.
Major work dude. the biggest problem you would have once you manage to tear out a huge piece of firewall to make room for the tranny is chassis flex. The car was designed with the torque from the engine going forward and backwards, not side to side. Your only hope would be a tube frame with scort sheetmetal. after you deal with getting the engine and transmission in then you need to deal with the front suspension. a 400 small block and a th400 behind it will ad a boat load of weight to the front. the rear end will also weigh more as the tranny sits behind the engine instead of beside it. not to mention you will lose you independant suspension on the rear unless you can figure out a way to bolt on say the rear end of a late 80´s supercoupe. the ones with the supercharged 3.8 v6. these had a great rear end setup for hanging turns. If all you want to do is go fast in a straight line ie. drag racing, punch the block a full mil, call JE or Weisco and get some custom dished pistons, stroke it, get goood head and exhaust. Add a turbo with a little bit bit of nitrous to move it along. When the block is in for the machine work have them o-ring it to help out under high pressure. Bolting in a 400 will cost you plenty and you may very well get tired of it. But hey, like old man Dan always told me "If you got the money buddy, we can maker ´er scream!"
Yeah, you´d be better off building a tube frame RWD 2 seater and figuring how to put escort body panels on it.
For HUGE power though...its all about the FI. Just go with a 4cyl build it like NORAD at Defcon 1 and run F*&$´n LOCO boost numbers and watch your tranny melt, halfshafts snap like skyscapers built on stilts, CV´s shear and leave an 1/8 mile of rubber. :-o :-]
