Need help with my 292 install in my 46 1/2 ton

[egarage]

I installed a 69 chevy pu 292 inline 6 in my 46 1/2 ton Chevy pu and then installed a Offenhauser intake with a Edelbrook 4 bbl carburator and then found that the carb. is now sitting at a angle because the intake is made at such a angle to make up for the angle of the engine. I had no idea that these engins were installed at at a such an angle. I'm going to have to make new motor and transmission mounts so I need to find what angle it should be set at or does some one have any other sugestions.
