I dont see much, if any, information on the Hughes website about which valve springs the hughes whiplash cam needs. I am considering this camshaft for my 67 383 with 30 over pistons (.034 in the hole) and 516 heads with stock 2.08/1.60 valves with a fresh valve job and hardened seats.

Anybody know what spring they call for? Is it a drop in spring using the factory keepers and locks?

Sorry, first time playin with big block mopar.

I havent got an intake yet, but I am considering an edelbrock performer RPM or weiand 8008.

(yea gonna ditch the purpleshaft I had in it)
