[69fastback]

If you plan on working on the car. Get a small block. It is a real pain in the butt to work on a big block my headers touch the shock towers and is very hard to work on because of space. It does have its benifits you will never get the same kinda of feel form a small block. Me personally i would find a 65 or 66 that was pretty stock and then mod the heck out of it. Find yourself a 302 and bore and stroke it to 347. a 302 looks just like a 289 sitting in there. Good way to make a sleeper. Make sure to get some suspension work and disc brakes. It is not fun trying to stop a 400hp car with drum brakes I have almost wrecked quit a few times.
