Hi, I have an 86 s10 which im in the process of putting a 383 vortec in, I was thinking either a powerglide or a 700 r4. I know the R4 has a real low fist gear, and a .62 final drive gear, would this transmission work better on the street, and a little drag ?. The powerglide has 2 gears 1.76 1.0, So i figured the R4 has more top end capabilitie, and better accereleration, i want to run either a 3.73 or 4.10 gear in the differential. Would the R4 be a better choice, and the motor will have around 450 hp, around a 3000 stall, 4.10/3.73 gears, the truck weighs 3240 empty.
Thanks

86 s10, tranny

I think I am going to go with a 700 R4, and I want to run 4.10 gears, is there a way to calculate Rpm, with the .7 final gear, 26 inch tires, and 4.10 gearing ?
Id like to know how many rpm the motor is going to do at 70mph, Id prefer under 3000.
