got my 327 from a guy who is long gone and no info except he was putting this in his chevy chevelle i got it from his friend who was holding it for him.I got it looking like a stock motor but it had eldebrock carb and intake.Well got it home few days later noticed it had new frost plugs/starter so i decided to pull apart.I pulled carb&intake looked really clean then valve covers,heads clean,note i noticed the gaskets been replaced well i then pulled heads an cleaned up cylinders/pistons from sitting and noticed the .040 on them & the cylinder walls still have the hone markes on them so i turned engine over pulled oil pan had paint overspray bu new and the crank &internals looked really clean looked at crank and lookes to be machined pulled 1 main cap off to inspect bearing and lookes like and feels like new.looked in at cam and that lookes new same with lifters. so i now have to fine out what has been done to this engine and idont know were to start any help would be good thanks.
