mystery cam
I just tore down the engine in mt 65 GTO. It is a 73 model 400. The part number on the cam is 540233, The only info I can find is that it is a 61-62
SD 389. It is listed as a mechanical cam. However my engine has hydraulic lifters. The cam looks relatively new with very little wear. Is this the only Pontiac cam with this part # or an aftermarket grind. The end of the cam is stamped 1082R. Does anyone have any info that can help Thanks Danno |

That doesn't seem to be a factory cam. http://pontiacdude.cc/ He has a list of cams but those numbers are not there.It's not a comp cams number either.

Could that be a 1022r and not a 1082r? Speed-pro made a 1022r cam for Pontiacs, it was a 214/224 duration cam.

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.
