The Stovebolt Site Forums The Shop Area Engine Shop Modern rearend for 1951 Chevy pickup

Gentlemen,
I have a a 1951 pickup with a rearend of 56 inches flange to flange. I wondering which types of vehicle rearends with around a 3.5:1 gear ratio would work in my truck. I placing a TH350 turbo transmission in the truck.

james

maybe a s-10 4x4
3:42 or 3:73 can be found
g-80 is posi gt4 373 & gu6 is 342
These are the codes found in the glove box door
i used one in my 52 Pontiac

I measured the spring mounts, outside to outside and the rear end width from backing plate to backing plate then went to the junk yard with my measuring tape and found a rearend in a 76 Chevy 1/2 ton pickup would bolt in... It's a bit wide, but it works for now (actually for the past 8+ years).

I used a S-10 rear end from a 85 two wheel drive in my 34 ford it's 55 inches out side the drums..

I think you will find that an s10 is a little narrow (54" outside of brake drums). Grab a tape measure, there are lot's of options. Spring perches will most likely need to be changed, no matter what you decide to use.

My brother in-law "27Capitol" has a '51 also, and he chose one from a Pontiac Trans Am (I think it's a '78) positraction unit.

PP,

The rear end in your truck should be 62" flange to flange. Rear end chart

BTW, this chart is from the Tech Tips section of this BB. You would be well rewarded to take a look at the information there.

Thanks for information.

I really appreciate it.

I used a 9" Ford rear end from a 77 Lincoln Mark V. It has disc brakes. It came with 3.00:1 gears but I swapped punkins out of my 66 Ford pickup which had 3.50:1 gears. This was an improvement for both the Ford and Chevy pickups, as the Chevy has a 89mm tranny with .73 overdrive.

ackk NOOO not a ford in a chevy :P now its .... frankenstien
