Ok, I have indeed verified that there is NOT a 914 in the Richmond pick-n-pull. I did not get to the Oakland one in time. Do any people more local (it's a 4 hour drive for me) care to see if it's in the yard? I may make the trek again if it looks to be worth it.

i could run over there and have a look. but i don't have a camera right now, can you wait 'til thursday?

flipped diff introduces other possible weaknesses. reverse cam is the way to go. Dr evil used to have a corvair motor.....

dunno about the 911 tranny though. makes sense.

Why? 911 Transmissions run that direction. Mike was rebuilding the motor anyway so he used the reverse cam. I tried to convince him to use the reversed differential.

911 transmissions run in the exact same direction as a 914 transmission. The only difference is the locaiton of the ring gear. That is why it drives in the opposite direction. Even in reverse the input shaft runs the same direction, and the pinion shaft is turned in reverse at low speed , and for a short time only.

If you reverse the rotation of the input shaft on a transmission, every internal part runs in the opposite direction. The shafts have thrust bearings that take the load caused by the helical cut gears. If you reverse the rotation of the shafts, you are running against surfaces that were not designed to take a thrust load.

The only proper way to make a Corvair motor to a 901 transmission is to install a reverse rotation cam in the Corvair motor.

Cap'n.. Can I get your input on this????
