My LS6 springs have held up to 6800 RPM shifts for over a year now without problems. If the LS2 springs are the "upgrade", will they consistantly hold 7k RPM shifts?

These will be complementing a forged 347 w/ ported LQ9 heads and boost. My current Procharger setup for now, an 80mm+ turbo in the spring at 16+ psi

TIA

 

It isn't so much the RPMs, as it is the lift and ramp rates on the camshaft used.

 

I'm looking somewhere in the ballpark of a mildly aggressive boost cam. 224/224, .570/.570, 114-115lsa. Not exactly that one, but close...

 

Go with duals....


Give me a call sometime this week, I'd like to sit down with ya and talk about a few things...

 

Alright Bill. Friday night I'm off, I'll call ya and make a date

 

I can get you any Comp. spring you want.I can also get you a custom comp. roller.

 

Good John. Get me a .700 lift cam and triple springs. I want to run 4s
