engine mounting angle?

I'll be putting the motor in my project car this weekend and have a question or two about placing the engine mounts. I don't know where I read or heard this but I recall being told that the engine should have a small downward tilt from front to back when the frame is sitting at ride height and stance. So first, is this true? and second, if it is true then what kind of angle. Ibe backing up this SBC with a 700R4 tranny and the tail shaft of the tranny needs to line up nicely with the opening in the X member mid frame. I sure would appreciate anybody's thoughts on this matter. I am really looking forward to mocking up the frame and drivetrain soon. Thanks. Mike

Drivetrain angles

Mike,

I think the major thing is to get the drive-shaft angle and pinion angle to work in your installation..most engines do wind up with a bit of down angle to them..I dunno if this is the should be or the way it is deal..I am not even going to try and go there..

Hopefully you have your drive-shaft in hand so you can place it in and check those angles..You may need to adjust the pinion angle as well when doing this so be aware of that..

Another think is to check the drive line clearance in all conditions of suspension travel..Have seen that where the suspension moves and the drive line contacts a cross member so look at that as well..

there are some threads on this in the knowledge base that can help you..Referring to drive line installs..

I do find that I need to have some wedges and blocking on hand to temporarily support the engine and tranny in place while I measure and check the angle of the dangle so to speak..when everything looks satisfactory then finish up the motor mounts and bolt her down..

When doing this project it is a good time to have the coffee pot on and set back and look at what you have before bolting or welding..

If you look at your intake manifold, you will see that the carb sits slightly slanted. You want it to sit level.

As for driveshaft, the angle of the "U" joint at the trans should be the same as the one at the rear.

Poncho has got it right. Set a small level on the carb boss then raise/ lower the motor to where you want it, while keeping the bubble centered.When you have the fore and aft taken care of, then check side to side to get your motor mounts even. Needless to say, you want your crank centerline parallel with the frame centerline.
