    My Novak instructions call for placing a V6 in a CJ frame at approximately 4
    degrees elevation as measured at the carburetor base on the intake manifold. I have done this when I tested the initial engine fitment. It seems that when the carburetor base is 0-2 degrees the transmition (T-90) and Transfer case (D18) is at an elevation of approx. 7-8 degrees. The valve covers measure the same elevation as the trans.
    Has anyone found this to be normal?
    I will try to post some pictures.
    Thanks,
    Tommy

    I think I mounted my engine a little low. Seems to me it should still work if it's with in the ball park. I've been told you need to make sure the engine is 90 degrees to the axles. If you don't it will cause vibrations in the drivetrain. I think it was on some web site I think. :?

    You should focus on the 3-4 degrees on the carb plate. Everything in the engine is based on that measurement as all other parts are relative. Think of it this way - no matter what angle you put the engine, the tranny will be @ 4 degrees more as it bolts flat to the BH.

    FWIW - you can have @4 degrees left right alignment and not cause and issue as well. When you build a street rod you use this angle to keep the needle bearings in the U joint spinning so you don't get a flat spot.

    Thanks for the input. I think I'll leave it as is.
    I was thinking that if the angle was lowered a bit I would have better firewall clearance.

    I prefer to move the motor forward 1.5" to give the valve covers a little more room. I just redo the cross member and the tranny cover and it seems to work fine.

    So, if you use spacers to lower your T-case you are increasing that angle at the carb mount as well. Just out of curiosity, why couldn't you mount the engine level? Or any other angle for that matter.

    :iagree: I made my carb base level.

    :iagree: I thought that was the standard for carburetor engines.

    I'm having second thoughts now. Do firewall work??? or move the motor???
    The more information I can get the better I'll be able to make a positive decision.
    I appreciate all input.

    Engine angle and why - I was told years ago, and by my engine guy that some can do with or without the angle. They (and I) have found that the angle allows the oil to return to the pan easier which reduces the amount of 'gunk' I have gotten in my heads over the years. Some agree with it, others don't. I have always followed it and had no problems.

    Hot rods - they are know to tilt it to keep the tunnel hump size down in the car and with roller pins I talked about earlier...

    Drag guys - I have known a couple to use various angles to help with the weight transfer...

    I know the angle really helped when I repositioned everything putting the SM 465 in with it.

    Take it or leave it JMOP
