[V8] V8 crankshaft bolt pattern

[Tony and Lillie]

Jason,

First of all, the V8 engine complete weighs 473 lbs. As Steve B said, it 
bolts up to all Audi transmissions. If it were mine, I'd look for a 4000 
Quattro trans. They are manual lockers, and cheap(I just got a spare given 
to me). You can find the whole cars in the northeast for $2-300. Then, lock 
the center differential permenantly, and just use the rear output shaft. 
Then you just have to have an adapter (or different driveshaft) made for the 
driveshaft to the transfer case. As for LT1Q, I've been in contact with 
another guy who did one. He's not a lister, but is on motorgeek. His name is 
Robert Dupree.

Now, one other concern is, what is the stock axle ratio of that Trooper. If 
they don't match, you can only use 4WD off road at low speed. I just fixed 
this problem with a Ranger. 3.73 rear and 3.45 front.

On to the clutch. The distributor V8's have 10 holes in the flywheel. 
Therefore, you almost have to use one designed for the V8. They are 
available in alluminum, but $$$. If there is a way to bolt the Trooper 
flywheel to the flexplate, I'm curious what it is.
