Talking Engine angle??

Hi all, I've been on other parts of this board for awhile but this is the first time I've posted in this section. I'm working on a '46 Chevy Panel truck with a 350/400TH set-up. I just put in a Mustang II front end and had to cut out the motor mounts. It did have the original front motor mounts but I took them out because I was told I could split the bellhousing with front and tailshaft mounts only and a high torque motor. Well anyway its time to weld in the side mounts and I need to know if there is a percise angle the motor has to be placed at? I know it has to drain oil back to the pan and give the drive shaft the proper angle so I know a little angle is needed but I don't know how much. I've built six cars in the past but this is my first in about 17 years and I can't remember alot of stuff.

Thanks much.

I guess I should put in the rest of the info about the truck. I got it half built from a man that got sick and could not finish it. It came with the motor and trans, narrowed Ford 9" and 29 X 18.5 X 15 tires tucked under the tubbed body. The body is in real good shape and primed some what. Have to do complete inside work. Just need to finish it out now.

There should be no angle at all. Keep it as horizontal as possable.

The articles I've read recommends 1 1/2 - 3 degrees. I usually put a level on the carb base on the intake manifold to get it level. Good luck. BTW you've got a sweet year model to work with.

You want the tailshaft of the trans to match the angle of the rear diff..Get these two as close as possible but no more than 3 degrees..You want it tilted just a little to avoid nasty driveshaft vibrations from steep u joint angles..Every time i do an engine swap i try to shoot for the stock rear pinion flange angle to match the tail shaft.

Thats if the rear angle is stock..You can play with the rear pinion angle later on if you drag race..

Like custom says the angle can be found by the carb mounting pad, it is machined at an angle to the intake flange.

If your running fuel injection it does not matter, run whatever angle gets you the least pinion angle change.

One of my less important bits of info that's stuck in my head is the angle of the carb mounting pad in relation to the engine is 17 degrees (SBC). I have no idea where I remember that from.
