Engine and Transmission Tech

After reading this article, I think that I would stick with the Ford 9" for extreme performance. Good reading that explains a lot.....

Jaques and clan, strength is largely a function of ring gear diameter, as Jim B. states,(as long as companion pieces are also adequate). Number of teeth, in contact is a function of of pinion to ring tooth count. Higher numerically, will have "less" tooth contact, as pinion gear gets smaller, with fewer teeth,(higer psi loading of fewer teeth in contact). Second problem is distortion under extreme shock load. The teeth are very hard and do not tolerate much deflection, before they crack and then break. The 8"/9" ford designs are stronger per pound, because of "pinion drop" is greater, this means higher tangient angles of tooth contact. This means stronger, but more drag,(approximately 5 hp. between a 9" ford and a 10 bolt gm). Onward, roverman.

the 8.8 is tough, cheap, and easy to install with today's kits!

It can certainly handle the 250 to 350 HP engines that go into B's. More HP than that and it's a waste of time and money unless of course you're a straight liner in which case a completely new axle is in order!!

Have you guys lost your minds? Seriously, what sort of monster motors do you envision installing that you need that kind of heft in the rear axle?

Easy Jim- buddy, as we have previously learned, "some" consider the rear end/t-axle, a good source of fiber and ballast/lol. If a 8" is good then, math included, would not a 8.8 be 10% better ? Cheers, roverman.

What about a 9.3" Pontiac/Oldsmobile rear end? It's featured in the current issue of Street Rodder.

Thare ye go ! Whots in my 56' f-100. Long live the 9.3. Installed it in 1969 ? roverman.

A reasonably prepared 8" axle is overkill for any car that ever wore an MG badge.

Since you guys are talking about axles for truck projects, I think this thread belongs better in the Drivetrain section...

I picked up a Dana 44 axle yesterday. I'm going with Bill G.'s 4-link kit. Seems to be the most rear end and suspension one can get for a reasonable price.

Going with T-Bird IRS on the Super Tigers Keeping an all Ford Theme

FYI have two frames for my 57 Safari one original with 9.3 Pontiac and a second frame with a Jag irs and Mustang front susension

Lots of good info Jim - Makes this a good forum

I'll start a build thread on the Tigers when the Frames are done

Later, Chris
