[V8Vairs] Transaxles

[paul beck]

I converted my Crown with a Corvair 4 speed to a big car powerglide initially. That moved the axle line back about 2". The next step was to go to a C5 differential. That moved the axles back about a couple more inches. That did put the outside u joints at a pretty severe angle but that was resolved by shortening the C5 axle shafts and using the stock (C5) CVs inside and out. the CVs are capable of operating at a much greater angle than convential unversal joints. The car is still on jack stands waiting for a new set of coil over shocks and springs but the driveline seems to run out good in our initial set up test run.
One issue you will have to address. The powerglide vacumn modulator mounts on the left rear of the transmission and will have to be removed and the opening plugged. That means you will have to have a pg with either a trans-brake (not reccommended) or a manual valve body. If a transbrake then you will need a manual electric switch to engage the transbrake in order to back up. Works ok but is really a pain unless you plan on doing alot of drag racing. The manual valve body only means you will have to shift to low range to take off and then shift manually to drive.
My adapter came from Mark Irons (canyonmancorvair at comcast.net) and was well made (all billet) and easy to use.
