Stall issue"?

224/230 stage 1

Not that big. My 6.2 used to footbrake to 3600 before the cam. Put a 231/235 .617/.620 113+2 in it, and it footbraked to 2200. Did a little tuning and got it up to 2800.

I have a 6l80e with a Circle D 258mm 3400, but its loose.

I guess I need to go with a 9 1/2 so it can b more loose

Upgrade your brakes or get a looser stall. My 4400 would only foot brake to 2700. New brake system and stalls 4400/4600 on the street with street tires
