Motor Mount Tech Session: Article by Welder Series

Points to consider (in no particular order)

 -Many factors affect the location of the motor in a street rod chassis. Plan ahead. 

-The frame should be at ride height and rake when mounting the motor/trans.

-On MII suspended chassis, have the rack mounted. It is usually higher than the crossmember and can interfere with the oil pan.

-Get Inline Empire Driveline tech sheet re driveline angles. (

-Carb does not have to be level, but try to be close.

-Pinion angle (up at the front) should be the same as the crank/trans angle (down at the rear) and the u-joint angle should be 3 degrees or less.

-Crank c/l does not have to be in line with the pinion when viewed from above.

-Crank/transmission line does not have to parallel with the frame c/l when viewed from above. e.g. The transmission is in the center of the 
frame (located because of the stock x-member passage) and the front of the motor is offset to one side (usually the passenger) for clearance. 
The 3 degree u-joint angle is the determining factor, as above. (Per Inland Empire Driveline/Armando)
