Hey man welcome aboard, I bought a 66 2dr a couple months ago but don't have the time to build it because i'm currently building a 67 4dr with a 302 kinda done up. 427 is right the c6 is a pretty stout trans and done right that 352 could be built sweet. I'm a ford guy til the end and this is just an idea for you but, the availability of parts for 302's and 351's in the aftermarket world is astounding and you could budget build one of those motors and get sick horsepower fairly cheap. Not detering you from doin your setup which is way different and also cool as hell, but you have many options. Your gonna have a sweet setup in the end whatever you decide. I'm gonna run mine wit the 302 for now but i'm building a sweet 351w to slide in her eventually also while tryin to buy a house. Good luck with it and send us some pics man. |
