engine angle

[Mike Savelle]

putting together a second gen Camaro and when the motor is in , its higher in the rear, I'm sure the back should be lower but how many degrees ?

I've heard that the carb base should be level. Most manifolds are cut to slope down (I think 4 degrees).



Here's an interesting article from On All Cylinders regarding Jerry Bickel. It's not a Stocker, though.

There's two things to consider, one is the driveline angle and the other is that the engine is at least one degree up from level in the front so you don't get air trapped in the engine when filling with coolant.

Nice little guide. I need to redo the pinion angle of my Mustang over the Winter and this will help.

That is nice. I'm putting a 9" Ferd w/ladder bars in a Duster. That should help a bunch.

If this is a typical big tire backhalf car with the rear u-joint CL higher in the car than the front joint CL, having the engine nose down will help achieve desired operating angles on the joints while keeping the pinion angle negative or nose down - which is desired in a drag car.

Otherwise, using the OE engine 3 degree down in the rear mounting, you get into the "broken back" arraignment.

Plus, the oil pan, headers, steering, etc all have to fit each other. It takes some planing and time mocking things up.
