Thread: valve adj. on a 216

Tweet

the PG weighted about 3 times more than the stick shift. thats where some of the power went.

216's had oil pressure, just not to the rods. The mains, cam, and rocker shaft got oil under 15-30 lbs. pressure.
My '54 Bel Aire would make 85 mph or so, then I put a 3 speed overdrive in it, just about 100 mph on a long run.

Regarding the original question, my 1942 Army truck manual says .010 intake, .020 exhaust. Same engine as the civilian 216.

Pope....

The specs for the valve adjustment are looser for big trucks for most years although the components appear the same. It must be because of the truck's propensity to overheat under load.

Maybe GM just figured truckers wouldn't be so sensitive to a little more noise.
