I have a small update but first a question
If I drop my motor mount point down 1/4"-3/8" will this give me any difference in my tranny mount height or will it just carry the same amount I drop to the mount? How many degrees could I gain either way if dropping the same amount if from the engine mount to the trans mount is 44" ? Or is this a crazy question?

Thanks in advance

Here's the reason why I ask.

This is what I have for space under the oil pan to my frame. about 5/8" I'm close to 3.5 - 4 degrees down now.

Here is what I have between my G Force cross member and the transmission mount. (That's a 2x4 on the flat) I could also use more room to keep the 4l85 lower in the tunnel. I need room for a connection on the drivers side.

I don't have specific answers to your questions but I can tell you what I did. I put an LS7/T56 in my 71 Camaro. I used Moroso steel engine mounts on adapter plates and a G Force trans crossmember. I ended up about 3.5 degree angle which was about the limit for the headers I am using. Any less and the header collectors start to point upward. I also had to make a spacer for under my rubber transmission mount. I set the rear axle pinion to 3.5 degrees up and it works great.

Bill I have about an inch and a half to make up how much was yours? I know yours is a T56 just wondering.

I think I needed about 1/2 inch spacer for the trans mount. If you need 1.5 inch use can just use a 1.5 inch square tubing, very easy.

That's what we're going to be using.
