I wouldn't run an engine on a regular bases at 0.90. If it was my matching number engine and I only took it to cruises and weekend driver, then that may be a different story.

Only a sonic check can answer this question for you This is the real answer. But, as stated, what is your REALISTIC goal? Weekend runs with the grandkids for ice cream? Sure, run forever that way. Bracket racing ricers? You'll embarrass yourself. FAST racing? Could work, how much you want to spend?

If you really like the car and the price is right, I'd go for it. What's the worst that could happen? That you'd need to get another 383? Or sleeve the engine you have if it went south? I'm not even going to ask where someone got a 0.090 over piston set.

What I think too, 400 piston 4.34 is .090 over 4.25

Never thought about using a 400 piston. Looking at what's available, it seems you could find an equivalent compression height. Stock it looks like the 400 would be over 0.030 in the hole compared to the 383.

A BB stick car in great shape for $20k? If it were an AC car you'd be complaining about how I bought it already.

It could be that someone just "fat-fingered" .060, I suppose. Looks pretty decent for $20K in this market; wouldn't surprise me if a dealer buys it and re-lists closer to $30K. Agree, "all original" is an exaggeration, but I'm not seeing any big issues. Like every car, all depends on an in-person inspection. Nope. If you go to the link the OP provided on page 1 and scroll to the bottom, someone asked the question. The seller clarified that it is indeed .090 over. Regardless, it appears to be a nice car at a good price.

That looks great. I'd probably buy it and worry about engine specs later.
