what type rear and tranny did you tell me to get for a pulling truck? and what out of?

Thanks

if i was gonna get real serious about pulling, I'd go with a rockwell SQ100 rear, and a Eaton/Fuller/Roadranger 9spd.....both are considered to be bulletproof as of about 5 years ago when I was into trucking and hot rod trucks......the SQ100 is available in several different ratios, 3.90, 3.70, 3.55, and i assume they also go up into the 4's

what was it you said i could find those in? i know u said pete, and you said " or even, shudder the thought, freightliner"

how would a 9 speed work? you never hear them change gears going down the track.

what would be the best gear for pulling?

where would i get the wheels they use, that bolt up to a semi rear bolt pattern with like a 16-16.5 rim it looks like?

what kind of frame/chassis work has to be done?

what would be a good motor for it?

I suppose i better add that these rears ave very expensive....a rear axle will cost about 1800, the 9 speed is cheap because no one runs them in trucks anymore, like prolly 600 or so, there will need to be some pretty serious modifications to either your flywheel and clutch, or the input shaft the the transmission, as the 9 speed input is huge compared to a normal pickup shaft....about 3 times the size, but a good machinist shoud be able to make a custom input shaft to fit a pickup clutch, i've heard of it being done. And then there is the difference in bell housings, it would take alot of work to use a big truck transmission in a pickup, but IMO, it would be worth the effort for the use of the optimum gear ratio.....hey, you'd have 9 to choose from, but probably only need the bottom 5, and need air to split to the top 4

any ideas for a motor? i was thinking maybe 427 from like a C60 or so and do soem work to it, whatever i could for more horses

[O'l Buck]

you must have been replying while i was replying...lol

as far as what gear to pull in, you'd just have to play with it and find out what ratio works best for your engine.....I personally would go with a 455 Olds for an engine, but i'm an olds junky....or a 500 Caddy......I'd reccomend a 12V92 Detroit, but you won't ever get it under the hood of a pickup....lol......

I'm not real sure on the wheels, I imagine you could have truck centers welded into 16.5 rims, but might loose some strength. I think Agricultural floaters use the same bolt pattern on the 4 wheel floaters for the front axle. You might be able to find some info at one of the pulling websites to get wheels.

For the axle housing, I'd check around at the local trucking companies, most of them have junk trucks laying around for parts, so you might score good....i can't remember what the axle ID numbers are and haven't checked into any of that on the web. I know they look a little different than the SQHD and SQHP rears, but that's about it, they also are a little lighter than the other 2 if i remember right.

You should be able to find an SQ100 under any make of Big truck as long as it is newer than a 1989 ( i think that was the first year for the SQ100.

Eaton rears are pretty tough too, but they are more expensive to work on and harder to find.
