A big block should be fairly easy to make run low 11's (streetable) with a little more gearing and the right heads. I ran 11.30 @119 in a full weight '71 Demon with a mild solid-lifter 416 SB stroker and OOTB Edelbrock RPM heads, on 89 octane in the heat. 3.91 gears and 3000 stall, so it was pretty liveable on the streets with 28" drag radials.
