Hemi guys.....

The spacer between the K-fame & frame rails helps get the engine low enough so the carbs aren't above the hood when using the x-ram. It also provides enough room so the oil filter boss doean't hit the K-frame.
Now if one doesn't care about such things, I suppose you COULD simply space the engine up high enough to avoid this whole problem, but then you have to make sure your pinion angle is right as you've now tilted the everything UP to simply solve the clearence issue that can (crudely) be solved with a sldgehammer! Kinda like taking a step forward & two steps back! I have to give Terozzi & those guys credit back then as they had to figure this stuff out by themselves---we just copy & modify what they've shown us. My car has the heavy, cst Ray Barton valve covers, so they take up more room than the factory covers, so I sort of created the problem myself. With an inch or so sliced away from the area, I'm willing to bet my problem will be solved.
