whats better? my motor has high comp pistons, RV cam, stock heads for now ( d2teaa) plan on going with bigger valves, and its a 428. street master vs performer? what are there pros an cons thanks

 

With the RV cam you’re not going to turn a lot of RPM. What do you plan on doing with the motor, in a truck pulling/towing, mild street racing or daily driver? To half answer your question I’d go with the Performer just do to the cam you picked. The Performer is more or less a stock replacement intake. Street Mater needs some RPM to get things to work. RV cam may not work with the RPM range of the intake.

More info is needed to help you.

 

+1 ON PERFORMER for your application , do yourself a favor and clean up the port ends ! from the factory they are all jacked up and uneven .
