The engine sits level side to side but is an inch or two tilted down transmission side. Because of the engine mounts needing to be raised to accommodate the ac compressor, I don't have enough clearance on the floor to raise the transmission to make fore and aft level. With carburetion, it is necessary for the bowls and float to work properly...maybe not a concern for fuel injection? | | | | | Joined: Apr 2005 Posts: 7,440 Bolter | | Bolter Joined: Apr 2005 Posts: 7,440 | Tail down is pretty normal. There is a desired angle that someone will post soon. Having to cut and modify the transmission tunnel is normal too.

Most intake manifolds are machined to keep the carb. level.

Since you're using an injected engine, probably not a big deal how much as long as your driveshaft angles are in the good. | | | | | Joined: Feb 2000 Posts: 5,202 'Bolter | | 'Bolter Joined: Feb 2000 Posts: 5,202 | U-joint working angles are 1/2 to 3 degrees, more or less under ideal conditions. Thats tail shaft to driveshaft, and driveshaft to pinion gear. As long as the oil pickup is still under oil, and the u-joints are happy, it will work. Setting level doesn't mean much when roads have hills and turns, means even less with fuel injection, just look at how some boat motors are mounted ! | | | | | Joined: Mar 2010 Posts: 10,272 Renaissance Man | | Renaissance Man Joined: Mar 2010 Posts: 10,272 | Just make sure that your engine/transmission drop angle is parallel to your pinion angle within a degree or two to keep the u-joints happy.

Back in carburetor days they had cars in San Fransisco that seemed to do quite well on really steep angles. Ford vans were not only tilted but also offset to the right.
