stall
''thanks again, i knew the stall is too low. this is a 4.5 x4.5 572 12 yr old shafiroff combonation. dart funnelram with a book 1150.dart 360 with super mod porting. cam is a c rane 791/731 with intake 297@50 and 310@50 on the ex.He recommended a 5500 stall. I ordered a bte 9'' with the 4500 stall because i didnt want the violence we had in the old car just starting out. max rpm for this combo is 7000. i dont understand how you can run a 6400 or up converter on a 7000 motor. i know yall know yall stuff, yhats why im here. also, were still on 3/4 throttle, but are ready to turn it loose as he gets a little more seat time. i also went with the 3.89 for the 4.5 stroke because most of the 4.25 stroke guys seem to run the 4.11?
