Either I've got off the wall questions or I really suck at the search function... I'm considering getting some GT40 heads, or perhaps even GT40P's. I know that the GT40P's take a slightly different header, but was wondering if there is any difference on the intake side of things between E7's or the GT40/GT40P. Also, somewhat relevant, but different question, I'm building a carbed 5.0, which 4bbl intake would you recommend for a somewhat budget build?
There is no real difference on the intake side. Just get the lower gasket for a Cobra, and the ports will match right up.
Agreed. For the intake, a Performer RPM or Weiand Stealth are perfect for that combo and reasonably priced.
