Engine angle question

I finally got the transmission back in my jeep, but with the tranny mount resting on the skid plate the engine seems to be slanted down in the back (higher inthe front) How much is to much, I was thinking about shimming up the tranny to make the engine sit more level... I am sure I can do it, but the real question is .... how much rear tilt is to much?

Thanks
Nathan

I wouldn't be concerned until I started getting more than say 5-6 degrees slope. As you tilt the rear of the drivetrain down, the front tilts up. That can cause front ujoint bind if you have alot of lift or a flexy front suspension.

I've put an angle finder on several "stock" setups with 4-5 degrees of drivetrain slope..

BESRK is correct.

If you are worried, take the carb off and put a level on the carb manifold flange.
When it's level both directions, the engine is installed at the correct angle, around 2 to 5 degrees downward slope to the tail shaft...

REMEMBER,
'Free' internet information is worth EXACTLY what you paid for it!

My 5.0L swap is right at 3* rear down, with no skidplate drop.

Thanks guys, I have to measure it... but it seems more then 5.. the Matkins frame was 11/16 of an inch narrower on the inside.. so the main mounts are closer together and therefor the engine sits higher
