What valve spring should i use?

I have a 03 vette that I'm putting on crane 1.8 rocker arms and a magnacharger blower with 3.0 pulley. Should make ~8lbs boost. I don't plan to race the car but do run it thur the gears once in awhile.

I'm leaning towards patriot gold dual springs. Thanks!

What RPMs are you gonna be turning? Stock cam still I assume? Im sure you can get away with less spring, but on teh other hand, the duals will be fine on the stock cam. I prefer duaals for the safety. Dont forget, youll need hardened pushrods too.

Thanks, I'll only spin the engine to ~6200 RPM's. Stock cam for now, I may put a LS7 cam in it in the future. I have harden pushrods.

I have "heard" the Patriots and the Crane 1.8's don't get along and develop a harmonic. I would consider the new Crane beehive design for this setup or the 833's.

dual springs only! a must for boosted applications. crane #144832-16 or #144833-16 springs, depending on what seat pressure you want. i would recommend atleast 125lbs. of seat pressure.
