Cam swap, the cam that was in there was spec'ed for a 355 and was falling off. It was also spec'ed for a heavy nitrous motor and was running like crap. After talking with a couple builders we agreed that it was the cam after checking numerous other things. The car drove fine but if I layed into it, it wouldnt move for shit.

Cam bearings are junk. Not bad for 1972 originals.
I have no luck with this fuckin things. Gonna part it out. Something metal went through/ is in the motor though.

those scrapes look like they are from the cam gear, either from install or removal of the cam.

I dunno they werent there before when I put it in, but Steve(Badass355) took the cam out for me so I doubt it but either way theyre junk, lots of other scuffs and stuff on the others.

id prob just say f it and throw a cam in there, maybe its the pics but they dont seem that bad. if copper isnt showin and there not polished in spots id debur those scrapes and put a different cam in. atleast you could enjoy it for the rest of the summer. i remember i putting an LT1 cam in my 305 years ago and caught that bearing with the cam gear and scraped it like that. motor ran great until i tried 20/50 in it and Fd the lower end bearings.

Yeah been thinking of options, with 10w30 in there I have 60psi cold and goes down to like 50psi hot before.
I just dont want a new cam to go in with tighter clearances and hurt things. I got the cam originally from steve so it was used. The marks feel pretty deep though so I dunno. I could do just the front bearing but I dont want to throw everything else off. Just not having much luck anymore.
