I've got a 460 SCJ in my MK4 and as expected I've needed to make many modifications to accommodation its size and power. Case in point, the MSD distributor that came with the engine is too tall and conflicts with the air cleaner. When I look at distributors most don't indicate in the specs what the height is from the block to the top of the cap so it is a total guess on my part. Those of you who have a big block surely have faced this problem and have the solution to my dilemma. Sure could use some help. Thanks.
