So now we know that the $10,000 check didn't relate to this car------good, maybe we can reach a mutual understanding of what he has and what condition its in.

As for the sound of it running on U tube? scrath that off the list----------
Full roller engine-well at least rockers-
overheated because of fan clutch----------maybe, maybe not, overheated? probably------appears numerous missing bolts in accessories including rad support and coolant overflow tank which doesn't appear to have anything in it so coolant probably low
Appears fuel line runs to rear so must be efi electric fuel pump but is carbed?
Sparkplug wires over top of valve covers with headers usually results in burnt wires
Now-what was the original question? Any way, young man (I'm 74) welcome aboard-I probably have done more Camaro engines than these othe rguys combined and I don't believe that you have a $10,000 crate engine, but will try to help you any way I can. So ask away -
