ST single valves springs vs ST dual
I am having a little problem deciding which one I need for my application
the single one are rated to 54lbs and the dual ones are rated to 74lbs :hustler: My setup will be GT35 .70/.63 15-25psi FMIC built block ported and polished head and intake 75mm throttle 3" full exhaust system cam gears stock cams MS2 ECU Also would it be worth the ST valves in 1mm oversize? |
Call me at the shop (or email) and I can help you decide which spring is correct for your application.

I have singles currently in the engine with inner springs from the duals that Sav just sold me sitting on the bench waiting to go in when I have time. So far the singles havent had any complaint at 14psi @ 8500 rpm with stock vvt cams, stock soild lifters, and stock valves. And it has bounced off that limiter at speed with the singles.
What 75mm throttle body are you planning on running on a stock intake manifold? |
