What to expect out of mild build 360

Should run very low 13, and with no wheel spin and tuned proper, maybe a high 12 in the 1/4 mile.

3.23 gears and stock convertor it isnt going to run anywhere close to real low 13’s. Maybe real high 13’s if i had to guess.
Back in 1972 i had a 69 340 swinger. Headers and 3.55 gears. Ran 14.23
This should run better than that no doubt. I will say 13.70’s- 13.80’s
This all assumes he has a stock convertor
