Hey guys, I'm usually up in the 4th gen section, but maybe you can help me out. My father is looking at a 1941 ****** coupe, with a STOCK 1975 vette 350, with a BDS 6-71 blower on it. Paired with a TH350 transmission. its revving pretty high on the highway, so we want to switch up the tranny for a 4 speed auto. does anyone know of any transmissions that would bolt right on there? AND if that 350 is really worth pulling apart and building it up for a blower, or switching it up for something bigger and better. thanks

 

have you looked at monstor or patc trans. 4l80e is a good trans with close ratio. comes in 6 spd now

 

ive thought about the 4L80E, are all small block chevys the same bolt pattern for the bell housing despite the year?

 

up to the lt1. they use the 4l80 in the truck with a sbc (not ls style) in later years so i think thats why a 4 and 6 sp are around. it is a bit bigger than the th350-400-700r4. you can get a 700r4/4l60 that can handle some major hp. that would avoid the computer hassle.
