Getting the angle of the dangle

[DRJDVM's '69]

Lets talk angles....

So I have my mock up motor in..... T56 magnum is on its way..... got my Moser Dana 60 mocked up pretty close...

The k-frame I used has been channeled into the frame by about 1.5 inches so I'm gonna have to modify the trans crossmember since essentially eveything has been raised...motor mounts are set......axle perches on the Dana are not welded on....so basically I can tilt the engine angle, trans angle and rear end angle to whatever I want.

I figured I should probably work from front to back.....in other words, get the trans hooked up to the motor and then tilt the rear of the trans up and down until I get the angle I want/need for the motor...then modify the trans crossmember to keep it at that angle....

The intake manifold surface is parallel to the pan, so I can use that to measure the engine tilt back to front.....or I can use the crankshaft snout......

If I remember correctly, I want a "tilt down in back" angle of about 2-4 degrees on the motor....does that sound about right? Its an EFI car.....

Then get my pinion figured out for the rearend......since that will be dictated by the trans/motor angle

Since I can set any of these angles to whatever I want....any suggestions on what I should shoot for?

Any tips or suggetions would be great.... I've never set up all these angle before....
