Looking at a 5995 to use as a base for an EFI manifold, but I'd like to find some specs to see how it's going to play out under hood before I pull the trigger. Does anybody have any specs for manifold height, either to the lower face of the plenum, or to the carb mounting flange face? Also, I'm assuming that a single-4 top is available? I guess these have been out of production for a while, but there seems to be a few of them out there in the world. Any specs or experience would be greatly appreciated,
