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.

Spot on - what happend to your Strange shaft, Nic?????

Nothing lives forever....

Love it!

Herpes does.........

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

Workin on it Pete.

That's the spirit

I reackon you need 900bhp.....

Spot on Pete.

I'm with Nick on this one, bloow me caps of it last year so billets went in now i'm going for Motive gears as they pitch a lot better than Richmonds

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
