ET'S with ported J/or other iron heads SB

i didn't read this whole thread but the stock NHRA classes have many 340 A body's in the 10's using stock iron 2" x and 1.88" valve j heads..
about 10 - 12 years ago i watched a Demon (3100 lbs i think he said) turn 10.8's. Stocker of course. J heads, TQ, cast intake. Of course, big converter, big duration, big gears. But, lift was stock :) That was about 10 - 12 years ago, they were doing it then.
