    Big block chevy build, 489 stroker

    I recently acquired a tall deck 427 and have had the itch to build a stroker with it. I know its a HD std bord block as it came out of a 1985 wrecker w/300k+ miles but mags ok. It would bore out at .030 easily hardly no ridge. I'd use .020 pistons if I could find them. I was thinking with the...

    that what I thought I need a line that goes over the engine and one over the radiator. thanks for that part number I'll check into it. rockauto shows that gpd 4811315 to fit but their list of ac compressors doesnt include the A6so it probably wouldn't. thanks craig! chuck

    1985 Silverado K30 w/454 correct a/c compressor??

    on the top pic w/A6, does condensor have two connections on the passanger side? mine does. its a new ac delco condensor about 10yrs old now. I understand that the new ones are smaller and need to be 'fitted' to the vehicle.
