Years ago I ran 11.80s with the H.O. combo, but John Presing has been 11.50s at 113 mph using E7 heads. It's hard to compare NHRA and NMRA cars because NHRA cars get slicks and a better drivetrain, but NMRA cars (I believe) can use flat-top pistons and they can run with a much smaller combustion chamber. Either way it's impressive to run 11s with those heads, especially when there are lots of cars with aftermarket aluminum heads that don't run as well.
