For those that don't know, I got a 2.8 from an '88 Camaro on Saturday that I'll probably use in an eventual StalkerV6 project.
I was preparing it for storage, when I turned the crank a bit and heard something that sounded like dirt scraping cylinder walls. So I figured I'd better take the thing apart and see what's up. Sure enough, #5 cylinder has some not so pretty scoring... tho it doesn't look like anything that a little honing won't clear up. Then I started thinking about what the C/R would be if I put Al heads on it. So I started wiping the piston off to measure the distance from the top of the block to the piston, when I notice some numbers on the pistons. I wipe a little more gunk off, and I'm shocked to find what looks like a non-GM part number and .75 on top of all them. I get out my caliper, and sure 'nuff the bore measures 3.533", or .030" over.
So it looks like I got a 3 cubic inch bonus!
Hey Pat, didn't you say the guy you got it from claimed he put a performance cam in it? I might see if I can measure it and see what it's got.
So right now I'm thinking the next step will be to pull the pistons out, hone the bores and I guess find a set of new rings. I imagine if the walls got scraped, the rings probably did too.
