Just got back from my last cat show for this year(tranny has to be rebuilt and saw a 1934 ford coupe with a 502 marlin engine with a 6-71 street blower topped with home made injectors running(get this)a shot of 200HP NOS cheater system that he claims is putting out 1,100hp and he uses it on the street. Never been raced. Doesn't sound over aggressive, actually sounds tame excepty for the whine on the blower, but when he took off he actually did a wheelie for about 200 ft right down the middle of the street and the back tires(mickey Thompson) 32x14.5x15 actually hooked up with very little smoking. Really and incrediable sight. With just the blower he says he gets about 11 mpg, with the nitro, wouldn't care to guess. Made me want to call under my seat when I pulled out and everyone was shouting light them up.Probably would have layed a pretty good stretch but with my tranny slipping I just shook my head. Thank god for the bad tranny
