On a 1980 Z28 with a 350. From what I can tell it has updated roller cam, headers and a Holley 750 carb. The car gets up well and 1st - 3rd is quick. Gettting to 4,800 RPMs is pretty fast and easy. It’s a new to me car and I feel it can go farther. Are there any obvious risk points in RPM that I should be concerned or cautioned at? I think the owner put a Holley 750 because he was expecting higher RPM, or why the 750? Would you generally expect 6,500 is an OK RPM? I would like to give it a good run, but don’t want to blow something. Thoughts?
