the angle of the ****** input shaft should be the same as the rear yoke I believe.... around 3 degrees I believe
With full weight of body and engine resting on the suspension (ride height) the base of the carburetor should be level. On a small block chev, that means that the tailstock of the engine will be sloped down about 3 to 3 1/2 degrees from horizontal.
I disagree.....with the car frame/body sitting level, the carb flange should be level. Hopefully this will result in the engine being pointed up about 8 degrees, if you have the "proper" g***er stance!
If your carb flange is level the cylinder head is 3 dregees positive which should make your trans pan level as well. The drive line angle must be atleast 2 degrees off center up,down,left,right it don't matter
Squirrel---You are wrong!!! 99% of hotrod bodys and frames are not level when the car is at ride height. The carburetor doesn't care whether the body /ch***is platform is level or tipped up 10 degrees either way. The carburetor wants to have a level base when the car is in its NORMAL OPERATING POSITION.---which is at full engine and body weight on the suspension.
The carburetor doesn't really care....really....and the engine fits a lot better if you put it in so that it's at the designed in 3 to 4 degree nose up tilt relative to the car's frame/body, which means the carb flange will be level when the body/frame is level. I suppose you can do whatever you want, but the way I describe is how most folks do it, and it works just fine.
