We'll I'm back and glad to see you Inliners are here to help me. I'm going to try and answer these questions the best I can.It is the ol 235' 6 cyl. with 5500 miles on it. This engine I built about 2 years ago really runs good even with the wistle in it. The reason I'm saying wistle is because going to work today thats all I really heard, a wistle. The cranking compression at 3500 miles averaged 124 lbs per cylinder, comppresion ratio I don't really know, they are flat top pistons with an 848 head and ahydraulic camshaft.I'm running the ol stock 1 barrel rochester carb with fram air filter and a stock delco reyme distributer at 6 degrees advanced.We'll I appreciate all your help there inliners. Have a good 1.
