Sorry for the essay of a post. My 1982 Mustang GT is getting it's exhaust system installed soon. It consists of BBK shorty headers, BBK off-road H-pipe, and Flowmaster 40 series American Thunder cat-backs. From what I was told when I joined TR a year or so ago after exhaust I should consider changes in the intake, carb, and cam. From what I've heard many things in those particular bolt-ons should match for optimum efficiency. The CFM rating of the carb should match the CFM rating of the intake, and the effective RPM range of the intake should match the effective RPM range of the cam. If this is incorrect just tell me so. I'm wondering, if I'm building a low-mid range torque-based Mustang, what sort of combonations should I run? Suggestions so far have been the Edelbrock performer or performer RPM, a Holley 4150 carb of an undecided CFM rating, and a crane cam. Any alternate suggestions? If so, why? What CFM rating of carb should I chose if I don't ever plan on running F/I? What sort of cam should I look for? Is there anything else that I should do before looking into getting these parts?
Thanks in advance, Marcus.

 

you have the right plan, get a 600-650 cfm carb and use the perf rpm.

 

I was told the performer RPM was a mid-high range intake?

 

It is but overall its one of the better intakes out there. Its one you can even grow with. Mild 302 with Dart jr's, has same intake as above, 750 DP but its to big, Crower 512 536 cam and car runs 7:60's on maiden voyage spinning.

 

I ran the same intake, with a 1 in spacer. But I picked up when I went from a 650 to a 750. 308 spinning only to 6400.
