I need some advice on what stall you think i should run
new motor dart block
383 sbc 13.42 cr...210 afr elimanator ported heads.....super victor intake ported...4150 holley flowing 970 cfm....solid roller 264-272 duration with 634 lift...dart block...mahle pistons...scat 60 i beam rods.....eagle crank....600 hp at 6700 rpm peak and torque 540 at 5200-5300 rpm..glide 1.76 with 8 inch 5000 stall verter......tires 32x14x15...... .old motor made around 70 less horse and peak torque was around 4800-5000 rpm...old motor flashed torque dead stall close to 5300 rpm off my tach and the new motor flashes around 5000 rpm...i moved the torque peak up higher......i made 4 passes with car launches with tires in the air and 60 foots are down.05 .......also i was running out of gear in top end with 5.14.....so i have changed to 4.86 gears haven't tried them yet.........curious on what stall i should have for new motor i am guessing around 5500-5600.what do u guys think........the car has picked up et just loosing it in the bottom end and top end and gears should help top end...........tell me your thoughts and opinions ........thanks

Something doesn't seem right. The new Motor makes 70 more HP and I think it has to be less torque? Since it stalls less...Less Torque from what I understand. So I think the converter needs to be looser.
I would say about 5500 as a Minimum and I think closer to 6000 would be better. Don't want that motor to drop back too much with not as much Torque to pull it out. Just a thought. Maybe I am off my rocker? ops:
Also what was the old MPH? What is the new?
