there is some discussion in another thread about this and to not take away from the original topic of that thread I thought I might open up a new one I've tried a quick search on the internet why on a sbc as an example when the engine is level (front to rear) the carburator leans forward and doesn't sit level with the engine I figured its for the oil to flow back quicker into the sump when the carbs are level with the engine when its layed back and help get a proper pinion angle to the rear end anyone know why it was built that way? somebody designed it so there must be a good reason its been like that for 50 or so years. anyone got a factory fuel injected sbc newer rig outside they can see if its the same way or is it just the carb engines?
Not only chevy, but Ford, Mopar, AMC, Packard, and most every other car I've worked on was set up the same way. It's to give the driveshaft a straight shot at the pinion, and to lower the trans for a lower floor hump.
