Long story short, I'm running a 32 roadster with a 9/1 CR, 462" BBB running cleaned up ports and stock valve sizes. Present valve train is KB roller rockers, KB springs, locks & retainers, Crower Compu-Pro #1 cam (260-266 degrees int & exh adv duration) and Crower pushrods. The valve train originally set up for a KB #118 cam which was later swapped for a Crower Compu-Pro #3 which had just about the same timing, but the lobe center on the Crower is 112 degrees and the KB is 118 degrees. Understandable since KB's #118 is listed as about the biggest "Cheater" cam you can buy. The wide separation angle does contribute to a smooth idle. A little further down the road, the #3 Crower was swapped for a #1. Anyway, with such a lightweight car (2400#) I seldom spin the engine over 4000 rpm so I don't really need the big time valve train stuff. I am building a 462" BBB for another car and plan to run more compression and the bigger Crower cam along with dual quads on it. Along with all the KB & Crower valve train parts. My question is; what factory rockers and pushrods would work well with the milder (close to stock) cam setup in my roadster? It will have a new set of stock valve springs installed and rpm's will be limited to 4500-5000 at the most.
im running the 69 430 rocker in my 464 600 hp with 550 lift and a solid cam and i havent had a problem, and i spin the motor to 6000 rpms . i think that rocker would be fine for your engine .mike
