Question about LS motor mounts!! I have a problem, Look inside

[Steve Cole]

So I put my 2005 5.3/ 4l60e in yesterday and ran into a snag. Two questions: my engine is tilted back about 7 degrees. Is this too much? I know about three degrees is pretty much the "gold standard" everyone aims for but will I have problems with this setup? I am using the ECE clamshell type LS motor mounts with their transmission crossmember as well. I am also using the CTSV oil pan and I have ample clearance above the engine crossmember. I cannot shim the back of the transmission because it is 1/8" away from the tunnel pinch weld seam. I called ECE and they said this is pretty standard for their mounts. He suggested I convert to a high hump tunnel. ( I am not going to do that!). I told him I would never have bought their kit if I had known the severe angle it puts the motor.

Has anyone else ran into this issue? What did you do about it? Suggestions?

Thanks.
