Possible that it's a 115.5 LSA, that 110LSA number came from a source I cannot now find.

As the ports on the 302 head are not very large, on the worst ones it seems you can get your thumb stuck in there, IMHO it does not pay to use very deep gears. 3.91s would be the absolutely highest numerical ratio I'd go and I bet it would ET the same with 3.55s.

I respectfully disagree with Fast68 on lifter choice. If the engine has a realistic redline of 5000rpm because of cylinder head, worrying about lifter weight becomes secondary. I'd suggest the low cost 340 springs Sealed Power VS678 or Enginetech ERV901. 91lb seat load and 326lb/inch spring rate. Why risk a lifter break-in failure when a higher possible rpm has little value? The Bullet grind mentioned above has .474 calculated lift and 209 degrees at 50. The 1.625 installed height really begins to cramp at that lift.

Anyway, different strokes for different folks.
