GMPT-BC-15-242

One of the items on my resto-mod todo list has been determine what cam lives in the original engine. My intention was to use a degree wheel and dial indicator to determine this “forensically”. But instead I said f-it and pulled the engine in the fall of 2016.

Research indicates the part # in the title is the standard billet H.O. cam used in the last aluminum headed LT-1 (Y and F body) cars equipped with the final revision of the Optispark distributor. I was hoping to find a GMPP “hotcam” which was a popular upgrade in the day, but since I experienced no such love a new Comp Cams 467 / 280 XFI grind was in order. 😀

New Bumpstick!

New Bumpstick!

Scouring the internets I’m finding a few YoubeTube videos depicting the choppiness of this cam. I agonized a good while as to whether I would shoot for a lumpy, high duration + overlap bumpstick or instead aim for a more stealthy grind. Again, fuck it! This should be able to turn big numbers over 6000 rpm once I sell a kidney and buy the longtube headers I’m wanting.
