I haven't read the complete thread, but why the drop in compression from like 15 to 1 to 11.9 CR. between the years?

I ask because if I am reading right, E85 can work up to like 17 to 1 CR and we all know that power is produced by compression.

Just saying is all and I know E85 isn't mentioned here.....

Because 11.9 Static compression is a whole lot closer to a sensible compression ratio for a street driven Engine, 10-4 P.D.Q. 67. ? Mark H.

Here is a nice 420ci, developed by HIGGINS race heads in Australia made 864hp @7500rpm and 640tq on PUMP GAS. =D>

The Heads are 2.85 mcsa and with a 2.170 intake 1.6 exhaust valve. What makes this even more impressive is that it’s done with 4150 manifold / carburetor.
