Ford 8 inch rear

[Dave Haller]

Anybody out there using a Ford 8 inch at BVille? What kind of gear can you get for it? Will it handle big horsepower?
 Thanks for any input,

-are you talking about something like what the 4cylinder Pinto of the mid 70's?
 -We've run them in a G/fmr but thats not a lot of HP but the one problem we've had is the gear ratios are not easy to get a good variety.
 -something like 4.62 then 4.10 then 3.80 with nothing in between.
 -I don't see any reason to run an 8" where you'd be putting a lot of power to'm with an expensive engine when you can a 9" and we all know they'll take about anything you can dish out.

Actually, the Ford 8 inch is supposed to be almost as strong as the 9 inch and should have a lot of gears available for it, though not as many as for a 9 inch.  This is not the same rear that was used in the 4 cyl Pinto; this is a newer design that is used in the Ford Mustang amoung others.  I think it is also more efficient at transmitting power.  Having said that, I sure like my 9 inch Ford rear.  I think either one would work fine for you at BVille.

Jack Kelly with the 644 lakester uses one with his D and E gas Chevies been 240. He's not happy with the slection of gears. not many available for LSR.

Thanks you guys. Good info. I run a narrowed nine in my Beretta that has worked just fine. A friend suggested the smaller eight due to smaller size and weight. I don't think the gear choices would work as well as the nine. I'm starting a new lakster project and am in the planning stages. Thanks again,

There's a guy down in Denver CO. he's is a 8 and 9 inch guru,he told me that some cars from the 60's came with a 2:26 (rare...chickens back teeth) and some came with 2:35(rare but not too bad to find)

Dave,  
 Caddy has a 8 7/8 with selections from 2.28 up  
 Gm 8.5" starts from 2.41
 Gm 7" from 2.14  
 
 With all GM's about 4% more power gets to the ground than with a ford -- of course the down side is ratio changes and c clip eliminators required

hey Sparky, On the plus side those old GM rears can be had for free in many cases if you're willing to take the whole car and junk what's left LOL

A Strange dropout 12 bolt or dropout 8.8 (ford)gives the benefits of a 9" with more efficient gears . Does anybody know who made the deal that allowed 12 bolt gears to bolt into a 9" center section . I think it used a custom spool and a custom pinion carrier that moved the pinion upward .
