13:1 Compression Pistons in 340 Small Block

One more thing on e85,
I had the opportunity to run my 12.5 440 on race gas for the camshaft break in and we made four pulls setting up timing and carb then we switched the carb and fuel to e85. What we saw was the peak numbers go up 18 tq and 15 hp that was expected but the torque down low went up 20 ftlb.
