Another question. I'm building a 383/438 stroker for my customers 68 Charger that has the stock hood. Would I be wasting my time going with the Edelbrock Performer RPM intake if I am using the stock factory exhaust manifolds? Should I just go with an Edelbrock Performer intake?
Thanks Darren

Unless what you’re building is very mild, the RPM should be better.

If you're worried about the RPM being choked by the exhaust you can relax a bit. It's a distinct improvement over the non-RPM on most motors regardless of exhaust used. Granted, better exhaust would help but you're not at the point where the exhaust will cancel out intake improvements.

Generally speaking, if your manifold motor is in the 425 HP rrange, the regular Performer or CH4B are fine. After that, there will be some power advantage to the RPM. Also the Performer and CH4B will do better over 425 HP with the divider milled down.

Thanks everyone for the feedback. After speaking with Dwayne Porter I think we are going with the RPM and a Lunati Voodoo cam for this build. Thanks again!
