Question
I have a 1984 corvette 5.7 350 engine with 119k miles
I did a compression test and found that 6 cylinder had 125lbs and 2 had 100lbs what should I have, or is this okay

Thanks, Ray

Answer
Hi Ray, if the engine is working ok, I wouldn't worry about it. but if you are having problems with it you should have it checked. There should not be more than 20% difference from the highest to the lowest, Yours is just on the border line. I hope this helps you, if you need more inf just let me know. Regards, Keith.
