Valve Spring Input Please.

Valve Spring Input Please.
Was looking at getting an MS3 cam, but decided to go with the TSP 228R ( 228/ 228 duration 588/ 588 lift on a 112 lsa because the powerband ( 1600- 6300rpm ) would be more streetable where I live as opposed to the MS3 ( 237/ 242 dur 603/ 609 lift 2300- 6800 powerband ). My question is, I was going to get the PRC spring/ pushrod kit and the springs are good up to a .660 lift. Just wondering if I should go ahead and get this kit or get the .600 ones. Later this year if not at the beginning of next year I will be putting the MS3 or MS4 in and I will need the .660 springs. Just wondering if they might be to much for that little while?

i would use crane #144832-16 dual springs. springs are good to .650 lift w/.060 coil bind clearance. 115-120lbs. on the seat at 1.800 on the seat, and 350-355 lbs. on the nose at 1.150. www.cranecams.com check them out.

depends more a cam profile, i have used these springs on everything i do, they should go to 7000 no problem, but i would probably shim them up like you have done, or run there #144833-16 springs. these springs are 135+lbs. seat pressure at 1.800. what's your cam profile? i think you would run out of cam, before you run out of spring. i always base my spring selection on cam profile, but the #144832-16 springs will pretty much take care of 90% of the cams out on the market right now. if you would like added spring pressure, without having to shim anything bump up to the #144833-16 springs.

It's a 230/236 .592/.602 112 LSA. It peaks at 6600, but my tach is real laggy, and I don't have a shift light yet, so I need to plan for the occassional 7k+ shift on accident.
