Well, I’m running a 360 with 11.25 cr, cranking psi is about 200/205. Cam is not to big at .246/.252 @. .050, 110 lsa. On top of that I’m running the old hustle stuff mechanical six pack, end carbs don’t have mixture screws but I have the transfer slot’s squared, if I run more initial ( which I don’t think I need with the all that cylinder psi) I then have to turn the center idle screw down to far to get it to idle under 1,200, which in turn makes the car want to die at stops. I run 93, but even with 28 total the car will annihilate the drag radials.
