Thread: Engine angle

Tweet

I have installed a new fat man suspension on my 1940 Dodge. I am getting ready to test fit the motor and mount the motor mounts. I am curious how much of an angle the motor should have? I am pretty sure the engine does not sit in the car perfectly level. The angle will affect the carb floats, so I think this is important.
Thx in advance.

Ideally, you should be able to lay a carpenters level on the carb mounting surface and install the engine dead level. I've rarely been able to hit it right on, because of clearance issues or cosmetics.

My daily driver Jeep has the 5.0 mounted on about a 3 degree rearward slant, and it has worked fine for years. My '27 sits on about the same slant, no problems.

But if you ask the experts, it should be dead level. Sometimes there is the "perfect world" and other times, the "real world."

JMO,

3* to the rear of the vehicle. intake manifolds are cut at 3* to the front, so that they sit leval @ 3* to the rear

Yep, the tailshaft of the trans should have about a 3 degree down angle, and that will make the carb flange just about level. Then, the differential yoke should have about a 3 degree up angle.

o on the tail shaft leve thru centerline crank to trans run the rear end 3 down any thing will work to a point long as the u jonts are not runing at the same plane . becarefull going up+ on the rear end with wind up will trash the ujoints for sure

Make sure you have the rest of the car weigt estimated fairly accurately, and mock up some weight for those components, also. Have a couple fat buddies stand on top of the frame and bounce it a few times too....or remove the springs and block it to where your ride height will be prior to setting your engine angle....

And it's perfectly ok to move the motor/trans to the passenger side of the vehicle as much as 2 to 3 inches if you have to in order to clear steering or whatever, so long as you keep the crank centerline parallel with the centerline of the car.

Good one Denny.Your getting better all the time
