in supers or open engine competition usually there is no carb spacer rule for height so compound angle spacers are common where the carb is angled toward the left and toward the LR at the same time ---this is possible with 1.5 to 2 inches of spacer to work with
in the crate world most rules dictate a maximum of 1 inch
working these angles into 1 inch of space is difficult
our original tilted spacer was tipped to the left 7 degrees
it left no room to do any antireversion work under the spacer so it was not real good on restarts
our updated version still only tips to the left but the angle was cut to 3.5 degrees which gave us the opportunity to work on the bottom side of the spacer to increase acceleration for restarts
it races very well and restarts excellent
here is a link to it

many dirt late models today have the engine tipped toward the rear and that compliments our angle to the left perfectly
