was up guys, first of this is for a truck silverado 1500 pick up, doing f1a with a 6.2 forged rods and pistons stock crank. Well my question is what gears are the lowest i can go without affecting the powerband, also want a tighther stall ..... My last set up was a 6.0 pushing 761rwhp thru 410 gears 4000+ stall and it was running out of gear at around 12xish mph or so @ 671rwhp since my shiftpoint was set @ 6500rpm and the rpm needle will never come down from 6k


look at this video (rpm) my speedometer had issues and will sometimes get stuck and that seemed like the problem on this video, or unless it was something else?


what gears can i use? what convertor should i use? i want my truck for rolls only dont want track

^ jesus christ that thing never let go of 6k!


assuming the tires on that thing are even factory, gears should probably be around 370-355. by the time you calculate the actual ratio is should be right where you need to be. boost likes long gears.
