Yeah,I was thinking more along the lines of a cam to run the numbers and not the whole package given the limitations you set.
I can say one of the most impressive street combos we had was a 360,j heads with 1.88/1.6 valves mild port to 230s/160s,10.1 compression,284 .484 cam installed straight up 108/108) rpm air gap,750 holley double pump and 3.55 gears.This thing had some serious low end and ran 108 mph in a porky *** challenger weighing in around 3,600 with a way too tight convertor that wanted to die in gear and no real tuning. I think with those things fixed it was capable of 110+ mph.
I have no problem with the 284/484 cam but in a perfect world personally would like to see it on 1.6 rockers as its a bit short on lift with 273 rockers. I still see it as a solid 12.0 project but if you check every box from weight to chassis to tune and the stars align you might surprise us all. I still say if it don't make it I would hit with a 100 shot lol.
