Maybe "3973493"? That's the only "493" that shows up in any of my books.
76 CC chamber, decent runners, 1.94 intakes. Not a bad head. That price for a Chevy cam is OUTRAGEOUS! Flat-tappet, right? Awfully small for a roller. In the boat, I would recommend Comp Xtreme Marine 12-240-4. Good for the compression ratio and a jet boat. RPM range (advertised) 1,600-5,800. 226/236 @ .050, .480/.489" lift, 112 LSA. Very good for an "A" impeller. That should cost about $210, cam AND lifters. Be sure to put a high quality timing set in there at the same time. New valve springs wouldn't be a bad idea, either.

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.
