Cam is modern replica of the L79 hydralic,447/447 lift, duration @ .050 222/222 with 290/290 adv.duration (some list at 306 instead of 290???);valve timing @ .050 intake 1*/41* (open/close); exhaust 49*/7* (open/close); valve timing advertised, intake 40*/86* (open/close);exhaust 88*/38* (open/close).
Motor is 4.00" bore/ 3.00 stroke; pistons are original static 11:1 when used with 64cc heads but I "might" try to use a set of 58cc heads "if possible",if not then 64cc but I am using 58cc for the 'cyl.head vol.' figure in the calculator. Gasket thickness is .016"; gasket bore 4.166"; deck clearance is a 'measured' .025"; and 5.7" rod length. This will be a weekend cruiser on race gas,cam 2 or so,,,
So Shawnlee 28 if you or anyone else would be so kind as to compute and advise it would be much appreciated.And notice my italics,,,,I know a degree wheel and precise building measurements will be required.Thanks,Jerry.
