I have a set of Gt40 heads that I am going to home port, a Cobra intake that I am going to have Tmoss port the lower, a C&L 76mm trueflow intake pipe, I am going to buy a cam( don't have a clue yet), some 24# injectors and a set of headers to finish out the exhaust plus the stuff in my sig. My motor has 106K easy miles on it and is very reliable. Is it going to be worth breaking the seal on a reliable motor to do the upgrades that I have listed? I have done a good bit of reading on cobra motors( which is basically what I will have) and the numbers are not making me want to tear my motor down. Who has some experience with this? Don't even care about hearing about alum heads or different intakes, I already have the Ford parts and I'm going with them or nothing at all, I want low dollar power.
