Hi there, so recently I had my lifter hold down fail and ended up having 4 rollers grind down to the cam, sad.. So I'm pulling the engine to clean it all out and inspect the journals and bearings. Since the B cam i have in there is going to be replaced. Im looking to try a different cam. I however managed to get some edlebrock rpm heads brand new for less than half price. I currently am running some ported d00e's with bigger valves. So I have a stock bottom end, .30 pistons, RPM 2 intake EFI, 70mm tb, 24lb injectors with maf. And i was looking at the EDL-2221 cam Duration 298/302, Lift .520/.520. Thanks for any input on cam selection, its very much appreciated. Basically i was wondering if having a matched edlebrock setup like their performace pack be better than mixing a different cam in there.
