8 3/4 strength

Braced, good shafts and spool seems to get the job done. Think of the weight saving over a Dana/9 inch.

This is why i asked about NOS.

NOS adds so much low rpm torque it kills rear ends easily.

Weight is indeed a factor but one would expect the owner would have the sense to use much lower gears on a heavy car and therefore get around that.

Hey Nick , that ole light weight B body will survive on an 8 3/4 , as will all the A bods , put some real power through a heavy ole B body then you need a Dana.

Hey , 700 HP through a 4300lb b body won't cut it with an 8 3/4.

You have made the weight criteria, all you have to do now is make the horsepower

Only messin'.......pass the red wine

Personally, if I was building a heavy car with a shedload of torque, and I was going racing, I wouldn't be throwing any money at an 83 /4". Given enough weight, torque, and a sticky track, there's nothing you can do to keep an 8 3/4" in one piece, it will break, it's just a question of when.....

Couldn't agree more, better spending money on a different axle.

I prefer a 9" over Dana's, but that just me. My cars fairly light, but torque was the key issue for me... 1000+ ft/lb from 2500rpm through to 5,000rpm

Soon be home

Had to read that twice then, thought you said in your B1 Bentley

Yeah, I was really surprised mate, torque curve just stayed flat

Converter guy was having a chuckle, when I was giving him the car spec

Soon be finished here in Poland, so will eventually have some time to sort the motor out. At least I have stopped it dying when it goes in gear, idle is a lot better, till it gets to 140 F Degrees.

Pretty sure it something in the warm up program.... taking fuel out, motor runs leaner & picks up like a crazy horse. Motor loves timing, seems to be the more the better.

Will have another go at taking some timing out or adding a bit more fuel or combination of both.

Hope to book it in on the rolling road, so can have a better shot at curing it.

Sorry to high jack your post Ade,

I mean Lee
