I reference his combo. His stall is to low for that motor with that cam and compression. 4500 would work a lot better. If the car don't 60 foot a higher stall converter will be the way to go. This is just experience I have had.
The video above the car went 10.79 and weighed 3850 with driver. stereo playing, spare in the trunk through the mufflers, LOL Barely got it wound up in drive, 5500 stall . What gears do you think?
