easy question... springs
easy question... springs real simple question. Will I be ok using the same dual valve springs if I swap out for a bigger cam? (blower cam to something similar to EPP cam 232/240 .595/xxx lift 115 LSA). is there anything I need to upgrade for this swap? going into a forged 347 8.7:1 CR set-up for turbo... but it will be NA for quite a while.
not sure on mileage. I would assume less than 8 thousand. Precision dual springs.
current cam is a 220/224, .551/.551, 114. thinking I'm going to buy a 23x/23x, .59x/.60x, 114-115 LSA cam. I just don't know if these springs are going to be too weak or not. what's the easiest way to check the spring pressure?
and with the lower compression I wonder if I will benefit more power being NA with the bigger cam?

Why are you putting a low compression ratio build in your car now with out the turbo? If you don't need it for the car to move I'd just wait until you have the money to put it in there.

I would check the spring but the PRC springs are good for .660 lift and your running a .595 and moving up to a .60X lift. I would thing you would be fine, I have the same springs on my engine and usually change them out a round 20000 mile or when i notice early valve float, I shift at 7400 rpms.

Ive been running this motor for two years now with no problems at all, I build my own engines. I ve had the rotation assemble balanced to the tee. The crank and rods and pistions has been matched and the rods have ARP L19 rod bolts. Ive put over 15 grand in this engine. It had alot of wot runs with a 300 shot of nitrous. Im going to use the same rods and crank in my new 434cid. next spring. 4.100 stroke with 4.100" bore.
