TRW #274. I've heard they work well in a 305. I can't find anything searching google as far as specs, or even if it's still availiable. Just doing some homework on a future project, Thanks.

Very similar, though not identical, to the "929" cam from Chevrolet, which was installed in millions of 350s & at least some 305s, as well as other SBCs. it would be a very streetable mild cam for a 305...no rough idle to speak of & good low-rpm torque.
