the reason for this is because i have a tranny and a edelbrock intake and carb for a chevy 350.... and since im 17 and alil tight on money and just want a fast car im thinking this would work..... and for all the performance catalogs i have looked in its WAY cheaper to build a 350 than a 302 or 351!
There are a LOT of people going fast for cheap with mostly stock Ford parts. You just need to be careful choosing them to get the combination just right. If you are going to have a full time race car with a built engine with every possible thing the most expensive part available inside it then Yes....the chebby drivetrain will be cheaper. When you're 17 and "alil tight on money" you have to go the cheapest route......in this case that is stock Ford parts.
Assuming you already have a 5.0, 1984 stang, a good start in the modification department would be:
8.8 w/ 3.73 or 4.10 gears
complete aftermarket exhaust system
GT40 or GT40P heads from and Explorer
spindles & front brakes from an '87-'93 v8 stang
good quality aftermarket lower control arms in the rear
rebuild / replace all suspension bushings, ball joints, tie rods, struts, shocks
complete tuneup & some careful tuning.
You will be surprised at how the simple, basic things can make your car feel so much better.
Remember that it is more important to have a reliable car than a fast car if it is to get you everywhere you need to go. An older car will cause you plenty of late night work on it because it's broke again sessions. An older car that is you daily with modifications will cause you to pull your hair out if you plan to do anything in your life besides working on it.
