Mounting the Hyper 9 Motor to the T56 Transmission was supposed to be a walk in the park. Unfortunately the adapter I ordered from CanEV refused to go onto the shaft of the Hyper 9. I sent the hub back to CanEV for them to bore it out a bit and fix some damage I caused while trying to beat it onto the motor.
Once I got the hub back and mounted on the Hyper 9, I discovered that the flywheel bolt spacing didn’t line up. Apparently the Chevy Small Block pattern that CanEV uses is slightly different from the LS3’s bolt pattern. In any case, I had to slightly grind 4 out of the 6 holes, and enlarge the other two. It remains to be seen if this will affect the balance of the flywheel, but as it’s pretty close to the center of rotation, I’m less concerned.
I’ve also been working on a front transmission/motor mount, which is coming along nicely.
Close, but no cigar.
After assembling everything and getting it 99% installed, I discovered that the T56’s input shaft was hitting the shaft of the Hyper 9. The only two options to fix this are to either drill out about 1/2″ of the center of the Hyper 9 shaft, or cut down the tip of the T56’s input shaft. I’m going to go with the former, as modifying a T56 Magnum isn’t something I’m keen on doing.
