Elgin camshaft
Am looking for intake Valve closing ABDC:
I am trying to calculate for compression for this E-578-S camshaft I purchased years ago.
With 1.5 rockers
Intake .429” valve lift 209 @ .050”
Exhaust.444” Vlv lift, 220 @ .050”
I believe the website says 112 LSA Intake, 116LSA exhaust
some number: 2899206
the plan was H116 Speed Pro pistons on J cylinderheads,
Block and heads not milled.
Daily driver 360, 2.94 or 3.21 geared axle, 4K pound car.
I think this close to the 340 automatic camshaft.
