Post subject:  Automatic transmission w/ differential or quick change!
I ran accross some cool stuff from the guys out West. They are experimenting with automatic transmissions coupled to either a quick change rear end or a modified differential like you would use in a dragster. I have seen this before but now it seems to be catching on for mid-engine builds. Heavy-yes, mid-engine only-yes, practical for a woodsbuggy-maybe. The weight would be centered in the chassis but the wheelbase would be quite long. Who doesn't have a small block something sitting around and a spare automatic. The only real cost would be upgrading of the engine and trans if desired and the differential. Custom frames would be a must. Output flanges for 930 and 935 cv flanges seem to be available for the differentials. Some are directly coupled to the quick change and some run a short shaft. A stubby powerglide would be short with a direct couple but not great since its only 2 gears. What do you think?

1st gear in a 'glide is a pretty long gear. Seems to work well in Mark Settles' Predator! Might do the same in a buggy with taller tires. (Tall tire to me is more than 31" :razz: )

Clayton did a similiar set up on his turbo VW powered drag rail. I think he used a Celica Supra rearend coupled to a 'glide, 'cause it has just a hoghead w/ flanges on each side.

Those stubby rear ends and Quick changes are HIGH priced stuff! I hear mid engine doesn't wrk great for climbing. Might as well do a CD if you gotta use a V8 in a woods vehicle, IMHO.

Ya, but chaindrives aren't good for the street. The differentials that were being talked about on the website I got the pics from were under $2500. A Winters or Richmond will run around $1500. The output shafts to match the 930 cv's would add some money. What does a built 091 cost and how much horsepower can it take. A custom diff and a decent auto trans can take 600-700 horsepower easy. I have a decent built C-6 with a 460 in front of it cranking out just over 500 horsepower and it doesn't miss a beat in a 4500 pound car. May not be the best hill climber but it would make a fun ride for trails and street.

I didnt know you were talking street or trail riding either. Was only thinking about how it might work when pointed at the clouds! :roll: Sorry.

theres one more way to go its a doug nash 2 quick plus it has quick change gears in the trans. so you could run a 8.8 ford ,datsun or something indepent for a rear end. 2 speeds with rev.
