Long Runner or Short Runner?

[FoxBuilder]

fastang, you are 100% correct most of the time they are considered long runner intakes. It's just me, but I don't like to break intakes down into two major groups (long runner or short runner). When I tune an intake system I could care less of what catigory it falls into, I want to know the exact intake runner length, head intake runner length and camshaft intake timing.

The only real reason you would need torgue at an off idle RPM is if you are involved in road racing or you just like to street race. In a drag car you shouldn't be at idle even when the lights are coming down. If someone lowers there launch RPM because of spinning they either have suspension issues or they need to consider getting slicks.

As the rev limiter goes it all depends on how the car is set up. A buddy's car we put together has a 306 with TFS Track Heat intake w/ 1" spacer, TFS TW heads, TFS Stage 1 cam, stock ECU, 4.30 gears and 28 inch slicks. The car goes through the traps at 6200rpm. This year we are going to remove the spacer and install the TFS Stage 2 cam, but we will have to extend the rev limit.
