Need Opinions on Rear End Options

This board has always been a good place for some good advice on my project, I have another item I want to throw out there for thoughts from others.

I have a 1963 Chevy project truck. It is a project as I have upgraded the engine (383 stroker) and transmission (700R4) but am still running an original rear end.

Any thoughts on my next project step in changing out the rear end?

I am interested in technical built thoughts as well as where to buy information if you wish to share.

One specific question that I have is that I currently have drums all around. I am curious what people think of a new rear end build with drums to match the front. Additionally, the truck is a 6 lug set up that I would like to keep.

Thank you
Abeis

You can never go wrong with the tried and true Ford 9" with ratios from low 2s up to the mid 7s. The 6 lug wheel is archaic and limiting as far as wheel selections, but if that's what you really want, you should be able to plug and redrill the axle flange

your rear end options

Hi from S Africa. with using a 383 stroker is it OK to use the drum brakes? I like the Jaguar rear end, suspension and disk brake setup. if the front suspension can be modified to fit the 5 or 7 series BMW front brakes and a diaphgram booster this will give cool braking and the B M W bolt pattern to Jag are the same. to keep the 6 lug pattern -with a little trouble adapters can be made.
The Jag diff has a wide range of ratios to choose from and is plenty strong enough to handle the 383 power. . . . . .

If you want to keep the 6 bolt rear and need a stronger one look under a 67 or 68 gmc. Some have dana 60's under them and should be the same width for yours. I had one in my 67 gmc with 3.54's in it.

Delaware and others

I would be interested in the information you have on an outfit in Delaware.

I have made attempts to get professional opinions, (not to insult you guys )specs and pricing from some well known outfits in California and Michigan and have surprised at the lack of interest in a potential sale.

The Ford 9" would be a good choice, have two center sections, one with 4.10s+ for the around town cruising and one with 3.50s in case you wanted to hit the road.

The one that's in it should be a 12bolt, it's pretty stout and there's a good selection of gear ratios for it. The downside is that if you break an axle you loose the wheel. A 9" ford is a little stouter and it's a semi-floating design, it's also a little less efficient than a 12 bolt. Another choice would be a 14bolt with a 9.25" ring gear that gm uses in light duty 3/4 ton trucks. It comes stock with 6 stud axles.

Which diff is in it now? If it is a 12 bolt you could always have some 9" housing ends put on and have a set of axles made. Add a Disc brake set up and you have a nice diff and spend way less than doing a complete 9".

Caution on GM 12 bolts from later trucks

1963 was the break-over year. Not sure on rear trailing arms. The 1960 trailing arms are narrower on pads than later 67. A latter model axle may not be a bolt-in on 1963.
