I will probably leave the carb for last, exhaust and intake first.
I have been searching, but which air filters do you recommend? I have the stock one that comes with the Roush 427r crate motor.
Sorry for all the questions, this is my first old style carb motor

Yes - bigtime. Imagine this: factory 1967 Corvette with chambered sidepipes & a 427 motor. Cut open the OE sidepipe chambered sections to find the flowpath (core) of them to be 1-5/8". Now how restrictive can that be? You don't have to be a rocket scientist to realize your motor just turned into a "pump" to get the exhaust past the mufflers. That equates to a LOT of lost HP. |
