Factory 4.56's with a 6.2 Diesel?

[mountainexplorer]

A friend just got an '83 Chevy 1-ton 4x4 SRW regular cab truck with a 6.2 Diesel. I told him it would probably have 4.10's or even 3.73's.

Turns out according to the tag it has 4.56 gears, and with like 27" tall tires. Proved me wrong.

Would you think it was special ordered that way?

It was most likely ordered that way for pulling. Top speed is the main thing that will suffer, but he can step up to 35" tires without changing anything in the axles

cucv's came that way the pick up variants did anyway

He could go with 40-42's easily enough with that ratio...with 27's it'd be on the governor at 60 mph.

Yeah, I told him that going down the freeway wouldn't be a very speedy experience.

He wants to lift it and put 35's under it. That is if I dont sell something and make him an offer on the truck he can't turn down.

He got it for $1700, and it's mostly straight and clean, and well-maintained. Has like 85,000 original miles, and it's a 4spd/205 truck. If I got it, I'd put the gas rigs to rest for a while as far as towing and highway trips. But it's gonna be hard to talk him out of it.

I've had two '77 1-ton factory smallblock Crew Cabs that had 4.56's, and have a friend with an '88 that had 4.56's... just never seen that low of gearing factory with a Diesel motor in a civilian rig.
