Yeah I may do that. Ok I emailed the guy for casting numbers so they should be here in about 25 minutes or less. Yes they are 4v heads. The ports are huge! Not sure if I want to use a 351C for a race motor. Not sure what kind of power they put out. I'd be better off with a 460 I think. Either way all this information I need if I buy the thing or not because I have a friend that may know someone that wants it if I don't get it. But yeah, how will it hold up to with that C4? Will the C4 hold up to a 351C pretty well?
Thanks again guys!
