Thoughts on the old RPM300
The 455 that came in my 76 TA needs to come out. Not wanting anything real radical but years ago I (as many others) had good luck with some of the cams in the 230@.050 range.
The 455 will get a set of cleaned up 96 heads and a set of RA manifolds. Poking around the garage the other day I ran across an old Isky RPM300 solid cam. With a set of 1.65 rockers I was thinking this might work out for the old pig. TA is a 4 speed with 3.23 gears. I have no problem running a solid and even have a set of springs for it. Should have tons of TQ from 2400 or so and be all done by 5300. So from the old guys tell me that I had a reason to buy this cam 25 years ago or so.  I just think it would be a fun thing to run. Basic specs. 270 /270 228 /228 0.448/0.448 0.493/0.493 108And this will be run at 6000'

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
