lian Posted September 18, 2009 Author Report Posted September 18, 2009 JUST GET WIESCO PISTONS TRIED TESTED AND TRUE sorry i am doing a full engine rebuild and am wondering if i would gain hp from boring and puting larger pistons in over just stockers. and if anyone has any good links with more info would be great Quote
sleeper06 Posted September 19, 2009 Report Posted September 19, 2009 You dont want to build the motor without freshining up the bore,I like to start fresh so there is no clearance issues with the piston.The piston/rings will last longer.Call a site sponsor and get away from the kit shit its too generic a good builder will give you a kit persay and there is no guess work on mismatched set-ups Quote
