Looking to get a little more out of my engine this year and a cam would do the trick and not cost a fortune. I've always heard that running a large cam on press in rocker studs would work the studs loose. The question is, what's too much cam? Currently my setup is a stock '59 389 Pontiac with tri power. Tri power was added, engine was originally a 2bbl. Thanks!
Hears a note from my uncle who used to race those cars yeaars back. On my 59 389 tri-power, I never had any trouble pulling a stud. The cam for the 345 HP engine was a #6 hyd. but NHRA let us run the Isky E-2 and E-3, I ran the E-3 and shifted at 6000 rpm with the stock press-in studs. I would suggest the 068 cam to replace the #6. The 886 was a real good street cam, the same cam that cam in Jim's 348 HP 1960 Cat. They used to drill and pin the stock studs, mostly the SD engines, but I see no need to do so on a stock type engine. My dad said the same thing, they never had a problem with them. Just stay away from the new cams with extreme lobes. Joe Hand
Pinning Rocker Studs is not a hard task - as long as you can get to the rocker base. We did this all the time when running small block chevys in a stock division where finances did not allow us to machine for screw in studs. a small drill and the pins from a universal joint bearing did the trick -
