[QUOTE="greg brillus, post: 172604, member: 597"] Some of this probably relates to how good an oil pump you use as well........the stock Vincent pump is probably not even as good as a hand held oil can........look at a bevel Ducati, has a much higher constant delivery pump.......still same roller big end.......Ok they had lots of big end failures, but i'm sure that was from a manufacture/hardness issue yes.......not from lack of oil.......Mr Speet, are you making these cranks to sell or for your own use only........Asking as i would like a shorter stroke crank for my race engine.......currently 92 x 100 but would like to go back to either 90 stroke or even less.......we are thinking of making a bigger bore race engine easy to go 95 mm but would need new cases with hold down studs moved out to go to 100 bore.......If you look at the Horner brother engines they use same spec bore/stroke ratio as a 327 Chev.......4 inch bore by 3 3/8" stroke.......this combo gives one of the best ratio's for good valve sizes verses piston travel/speed .......i would like some new cases with the hold down studs moved further out.......this was what John Renwick did on his 1600 cc sidecar engine.........Cheers......G.
