My question is what would be a decent axle for a 1954 Chevy 3100? It will be mated up to a 454 & a T10 4 speed. I will be getting a 4 link as well. Thank You... | | | | | Joined: Jun 2011 Posts: 5,096 Crusing in the Passing Lane | | Crusing in the Passing Lane Joined: Jun 2011 Posts: 5,096 | Any later rear axle with 6 lug bolt pattern, and desirable ratio.

Try one from a 1970's Econoline 150 van for approximately the right tread width. There's a trainload of specialty parts and pieces for that axle- - - -limited slip carriers, disc brakes, etc. and any gear ratio you can dream up, also.

Jerry Agreed, went back and reread post and see Jupiter did not note 6 lug, the mention of 6 lugs was the next post. I chose the blazer axle to keep 6 lugs.

I just realized I fat-fingered a key there- - - - -should have typed 9", not 8"! Here's a few ideas about building a custom-fit rear axle capable of handling a beaned-up big block Chevy: https://www.quickperformance.com/Ford-9-Inch-9-Ford_c_37.htmlJerry
