650-750rwhp to me will be enough. Then later maybe go DP and 300 shot.
I would think the stock rockers should be fine for a while... but the PP springs???....I'd be thinking 921's.
I have some dual springs from some other heads that were barly used but I dont know if there crane or comp? Is there a way to find out if I already have 921's?

Chances are thay are not 921's unless you dropped big dough on them before...not many springs deal well with that lift for very long...maybe 977s as well... I have no idea how to tell shich springs are which...someone here must have a clue. Damn manufacturers should copy polaris and paint the things all different colors to be easily spotted.

I got them from GTP with my stage 2 heads. I guess I'll give them a call

One our our shop cars has a 382 with a solid roller cam (352/362 645/650 112) We used CNC in Florida to do the heads. Pete is a bad a$$ down there. He put us in some triple springs and we used Jezel valve train. All titanium pieces up top to keep the weight down. The heads have about 12.0/12.5:1 compression. We are also using 1 7/8 to 2in stepped Kooks with 3.5in exhaust to an X and bullets. We just got the car put together. It runs and sounds absolutely amazing. We are looking to dyno it in the next month. We are waiting on the TH400 to get back to us. We, unfortunately will not have a dyno queen by any means. TH400, steel DS, 9in with 3.73. We will definitely post up numbers soon and better then that for sure some ET slips. We are going to spray 300 on this setup. (less then 3000lbs with driver)
