What degree do you mount the engine? What degree pitch do you mount an LS1 engine? And where do you take the reading from? Any information that anyone can give would be a great help.

3 or 4 is what i was told but as long as its no 0 degrees it should be alright. a surface parrallel to the crank. front of heads or top of block if you have it apart.

I didnt bother checking the angle of my motor. 3-4 degrees could be the difference between being on a perfectly level surface or on a slight hill. You can always adjust the angle with the trans mount with plates. I ended up putting a couple little spacers under my trans mount just to help get my driveline where I wanted it, but now that I know how to actually set my pinion angle correctly Ill be taking the spacers back out.
I think its pretty forgiving if you just use good judgement and try to make it so its not at some crazy angle.

Make sure the chassis is level before you start (both front-to-back and side-to-side), then check to see if any of the bushings are worn out on the rear axle. This seems to be pretty common on the A & G bodies we've mocked up on. Then measure the the pinion angle on the rear axle. The pinion angle will dictate the angle of the of the engine. This is going to be important to prevent driveline vibrations. You'll want to keep the angle on the front u-joint the same (or as close as possible) as the rear u-joint. and you'll want to make sure that you never run a zero angle on a u-joint. A zero angle will kill a u-joint since the needle bearings won't move. I try to get the angle on the u-joint between 3-5 degrees.
