Re: Compression test results, opinions please.
It appears you did a wet/dry test on 3&4,with a 10psi rise wet.This indicates the rings are losing the 10psi.Assuming you are using stock pistons and rings I would not worry,stock pistons use wide rings that actually glaze rather quickly.Basically its the nature of the beast,wide rings yield a long lasting bore but a reasonably high leakage rate.Using a piston with a narrower ring seals better...Ross pistons,SBC 283 pistons hold compression and control the oil better...me? I prefer the stock rings,leakage is upper cylinder lubrication in my opinion.
