POS Camaro

Lately I've been leaning towards a head gasket or more likely a bad or cracked ring. I need to find a compression gauge.

After sitting for three years the valve stem seal are dried up a probaly cracked, and/or the oil sludged and creating a partial blockage in the head oil return. Occasionaly it gets filled up to high in the valve cover and with dried out seals leeks thru the the guides to the combustion camber. Check your plugs for oil residue. Good luck

A little history of this beast. Yah, it sat for a while. I did ride in it before it was parked and it was sweet. I spent about a week and a half getting it to run. Took two months and a new catalic converter to legalize. Headers and all sorts of fun stuff to getv it on the local "international" drag strip. I ran 15.2 sec with a shameful rt. Had I a clue about what I wzs doin It've been 13 or 14 easy. I drive hard and Im pretty sure I caused these problems. Ya se, it seems to have gotten progressivly worse. About 10 miles or maybe 20 and im down a quart ot oil. It might smoke bad enough I can't see a car 2 lengths behind me or it won't smoke at all. There is a high pressure pump in the pan. Advance at idle is 8 deg and goes up to about 42. Plugs have MAYBE 5000 mi on em. Custom wires. 1406 Edelbrock. HEI. Forges pistons. Fat cam and a shaved deck. There is a slew of parts I want on it so here in a week or so I'm gonna pull it out and get it on the stand. We'll see exactly what the damn problem is. New parts will include AFR heads, Pete Jackson timing gears, chrome shit (March), radiator, water pump from Moroso, blah, blah, blah. Does anybody wanna take bets?

The 350 is now on a stand in my cramped garage. Prying it out of the bay was a real treat. I pulled the pan, one of the heads, and the #5 piston. I suspected rings but found the entire section between the scraper ring and the top gone. Jus kinda on one side ya kno. So, curious. I measure the bore and come to 4.12? Is this a 400 piston. I'm gonna look in the heads for casting numbers here in a min. Any ideas or thoughts on stuff I might want to check out?

Alright, it seems to be a head from a 305 manu in 86. I wonder if it could be suffocating. The valves don't actually look too bad. Is there some formula that can be used to size them?
