The people that are running in the 11's w/untouched GT-40's, what else do they have done to there motors/suspension, my goal is mid 11's N/A while retaining Smog certification, so there cars sound like what i would be aiming for

Thanks for the info

It would be very hard to stay streetable and run 11's with GT-40 heads.

The guys I know are running the stock short block with GT-40 heads, a custom cam and and the holley systemax intake.

These cars have no smog pump, A/c or power steering. You have to have a killer suspension set up and cut a 1.4-1.5 60ft in order to break into the 11's with the GT-40's

I highly doubt you could have a streetable 302 with GT-40 heads and smog legal and still run 11's.
