Motor/trans angle?

[bret]

I’m in the process of modifying my transmission crossmember on my 68 camaro for my swap. I’m using my stock front subframe and the car is currently empty except the motor/trans and rear suspension; no front sheet metal installed. With the car sitting up high with the lack of weight what would i use to help get a desired angle on the motor/trans? At this time I’m only worried about the motor/trans angle, not the entire/final driveline angle. Would i use the subframe as a zero degree reference? By the way the car is sitting on all four tires.

Here is the way I have found the simplest over the last 40 years...

1. Mock up the car so the rocker panels are level at whatever ride height is convenient to work on it/under it. Full weight, no weight, suspension under it or not, doesn't matter. Make the rocker panels level front to back. BTW...make sure the body mounts/subframe mounts are new or in perfect shape.
2. Install the engine/trans so it is 2 degrees tail down. Not 1 degree, not 3 degrees..certainly not 6 degrees. 2 degrees. If this means cutting out the trans hump/tunnel, go get the Sawzall.
3. Fabricate whatever engine/trans mounts necessary to mount those components.
4. Now when you install your suspension AND the suspension is mocked up at its intended ride height, set the pinion angle at 2 degrees UP.
5. You're done.
