I am scratchbuilding a custom 34 chevy, i don't want a ford 9", what is a good chevy version? Somthing that aftermarket gears and axles are readily available.

Something that is cheap would also be great, what vehicle to take out of?

a 12 bolt out of any car ,probably a camaro, nova or chevelle. The 2wd truck is good too, but harder to find gears, and lockers.

The 9 inch Ford is the most used, most transplanted rear in the Automotive world for GOOD reason.......

An 8.5 inch out of any car or truck will do you just fine for up to 400 horsepower and an automatic transmission, 350 hp with a standard.

Easy to find parts for and cheaper than most others because they've been in production for 30 years now.

Agreed... a stock 8.5" isn't much weaker than a 12 bolt, and debatably as strong as a truck 12 bolt. Not to mention the prices you pay for a passenger 12 bolt these days are outrageous.

An 8.5 with maybe an Eaton posi (skip the factory Auburn cone-style posis), bearing cap studs, a preloading cast cover, c-clip eliminators, and good quality axle shafts will take a TON of abuse. I'm planning on giving mine 500hp/500tq with 4.10s and a T56 six speed here soon. But I'll be limited in the traction department with 285mm rubber.

You can snag disc brake 8.5s from several cars and late s10 trucks. Taxis, cop cars, impala SS, some 80s caddys, late pickup trucks... just start hitting the junkyard and look for 8.5". This website lists them by photo:
