How much more RPMs can you get with aftermarket cams and a balanced crank?

depends on the cams.. say stage 2 cams and forged crank.. i could take mine to 6200-6500 i never took it that high though. if you want to spin that fast, also look into rods and pistons just to be safe

Dude i already have forged pistons and rods. . . . . Those stage 2 cams are rpm cams. They exceed what a stock motor can rev to.

ok then whats your question.. how high can you rev on the stock block?

ackuric

uhm, i think hes wanting to rev up to 7,000 rpm which would take a lot of work to be effecient in doing so.

you can rev to 6200 stock but your power drops severely after 5,500. with the aftermarket cams you can expect to continue making power up until 6,200-6,500, you may also experience some loss on the low end with that kinda setup.

you could probably spin up to 7,000 rpm with the right cams/valve springs and make good power doing so. code is the man to ask this question to, he has the highest revving 2v that i know about and makes power doing so

My old set up, I shifted around 6800-6900 and with new set up I will be over 7200.

The Patriot heads came with their own springs. Let me do some looking and see what they are. . .

.612" lift is all the info I could get of the PSII springs. Dunno what brand. Doubt this helps.
