What's your opinion. Do you think a GM 8.5 rear diff can be strengthened enough to handle 400ish ft-lb of torque?
Hey scroat

I guess so. I don't know or care much about hotrod stuff. Just buy something that was fast to begin with. Or better yet, go slow.

Pretend you did. I ask you because you are a cheap MFer and I'm trying to avoid another 3k on a 9" ford.

Actually he's correct.

Here's my cheap MFer advice: There's nothing wrong with a GM 8.5. Just put a reasonable engine in front of it. Reasonable engines are cheaper, more reliable, and more efficient. Hell, you might already have one around.

LOL well Ive got an over 400 hp and trq sbc, Since it is in a fairly light pick up and I won't be drag racing it... i'll give it a go.

See, there's your problem. I bet you could have got one with half the torque for 1/4 the price.

I could have... then I wouldnt have as much fun playing around with it. I've sorta been in this predicament before with an early fox body mustang. I broke 2 sets of spider gears (7.5") until I welded that mess solid. I'm thinking and 8.5 with a mini spool will hold up being it's in a short bed gen one s10.

I dunno what sort of truck you're dealing with, but you could see about getting a semi-floating 14-bolt out of a GMT400. They were all 6 lugs. In the pickups they called it a light duty 2500, and I think in the Suburbans it was a 1500 heavy-half option.
Edit: I read your post, so now I know what sort of truck you're dealing with.

I had a 1990 Sonoma company truck in the late 90's. It had a 2.5, 5-speed, and manual steering. It was great truck. No idea why you'd want more engine.

It's a gen one s10 so a 10 bolt should be plenty. If I have to narrow a rear I'll go with a 9 inch. The 4.3 s10 had an 8.5 10 bolt. I don't have much experience with the GM rear diffs so I figured I'd ask you as you are knowledgeable in the mechanical area.

Because it is fun to turn rubber into smoke.

Do you have an 8.5 laying around?
I'll text you my guy's number he owns five yards around the southeast.

The only thing special about a Ford 9" is its extra pinion bearing. That's what makes it strong. Well every heavy duty truck rear axle has that same third pinion bearing, including the 14 bolt. The semi-floating version has a 9.5" ring gear. They are dirt cheap compared to a 9", and probably stronger. Probably a little heavier, since it's designed to haul some weight. So what? It'll melt tires just the same.
