Hey guys what spring pressures would you use on a 680 lift solid roller bbc (seat and open) for a street/strip car.

As always thanks in advance,

Depends on the cam but no less than 200/500, preferably about 225-250/550 for most.
This is a billet right?

Hey Mike, thanks for responding. Comp recomends their 944. 190@1.95 755@1.2 pacaloy springs. I am thinking 952 206/557 but I would need to machine the head more. The 943 is best 240/598 but max rec. lift is 650 (was also rec. by compeven though max lift is a little short. The cam is custom ground 251/259 680 steel billet 11-000-9 . What do you think?
