It only matters if the motor is carbureted. If so, the carb pad on the intake manifold should be level with the ground. That is not to say that a builder could not cut the carb pad for parallel with the crank and install the motor level with the ground, particularly on a dedicated race car like this sounds to be.

I agree with tech.

I was taught to locate the crank at the frame c/l and to level the manifold on a carbureted motor.

i believe i can throw my .02 in here.
i have always set my engines to " zero bubble" on the intake carb flange.

since ive been building boats, ive found that getting the carb level under hard accelleration is the way to go.

im thinking that this is also applicable to cars.

One more comment...however the carb sits or if it has f.i. etc., another consideration is coolant...you need the engine up at the front a little, since the crossover passage and outlet on the intake is there, to help keep air from being trapped in the cylinder heads.
