I'd be looking at cam bearings...lots of nicks..

I wouldn't run that - replace it.

so this would mean breaking it down further i.e pulling crank and pistons/rods?

I'd get a good look inside. Those chips had to go someplace.

Thanks for the info man sad news really but better than putting it all together and blowing it up first week starting all over. ill check it out tomorrow after work cam bearing is something i should have a machine shop do you think?

You also mentioned it being dirty inside the engine. That combined with the condition of the cam would make me tear it completely down. At least pop a main cap or 2 and have a look see.

That is one of the worst billet roller cams i have ever seen..at first i thought it was a normal flat tappet style it looked so bad

Looks like somebody used it as a hammer in a prior life, wow, that's bad.
GM's cam bearings caused a lot of problems early, I don't know if they've fixed 'em or not. Several wouldn't even stay in place.
I'd pull the engine and tear it down completely. Have it cleaned, new bearings installed (ALL BEARINGS) and analyze the rotating assembly prior to reinstallation. As long as there isn't a lot of piston scuffing or damage to any bores, drop 'em back in and zip it up. Post pics if you have questions about anything.
Oh, and a new cam, that one needs to go on a wall somewhere with a frame around it.
Genuine GM LS7 lifters can be had for under $150/set, yours can't be worth much after riding on that scabby cam.

That can looks like it was used as a tweaker-be-good-stick before it was put in the engine. Scrap it, and make sure everything inside the engine is good and clean.

Geez, nuttin a 'lil Bondo won't fix!! 😬

 

[Salty Crusty]

^ Bondo won't stick, gotta use JB Chemweld.

Right-o! My bad!!😛

 

[Rebel n Dirt]

I still think it was a tweaker-be-good-stick... and if it wasn't, then well it's now got a new job, because it shouldn't be used in an engine ever again.

 

[Gen210]

Retire that stick, it will cause you headaches!

 

[oldeerslayer]

Just drop it on a concrete floor. The you'll have 2 or 3 camshafts.
