outlawsteve Posted April 29, 2020 Report Share Posted April 29, 2020 I have a old set of ported oem cylinders from LRD. they ran good for my setup. was freshing up the top end and decided to mic out the inside bore and pistons. there running wiseco 513m06600 66mm pistons. measuring from the bottom of the piston skirt or the widest part im getting around .009-.010 thousand clearance room temp for my piston to wall clearance. I know they require at least .003 thou. minimum but how far can I get away with? I guess I could go up to a 66.25 piston or 66.50 but isn't that pushing the limit on a factory sleave? I have some nice measuring tools so I know my measurements are spot on. any info or builders who run this much clearance? Quote Link to comment Share on other sites More sharing options...
SKEETER Posted April 29, 2020 Report Share Posted April 29, 2020 Just call Arlen and ask him. He ported em. Quote Link to comment Share on other sites More sharing options...
outlawsteve Posted April 29, 2020 Author Report Share Posted April 29, 2020 ill give that a shot see what he says if I can even get a hold of em. if .009 isn't to excessive ill just order another set of 66mm and go on about my build. ps. anybody know off hand what the 513m06600 and 513m06625 wiseco pistons measure out to be? tried looking on wiseco sight but no luck,tried to call with no luck as well. Ive been told theres like a master catalog somewhere with all the measurements Quote Link to comment Share on other sites More sharing options...
