Looking for some cam advice

Did you get the full port and polish?

If not...you are actually gonna need .600 lift to make anywhere near the power it makes now.

Those heads are nice, but stockishly lazy in flow under .500. Full Ported factory iron have the .500 and less of the full blown ported version 360 Indy.

None the less, you can get a pretty nice lunati hyd roller in the same lift you have..but spring will be in the same lifespan. If the heads did better at lower lifts, I'd recommend you drop the lift to .570 and stick with similar [email protected]

Lift is what's hammering the springs.
