I think that the blocks did change at some point based on a few people that have gotten Frankenstein engines and not been able to put together a conversion to a mechanical pump setup. Top is the timing gears for a 15B-F (I think it's the same as the 15B-FT with a rotary pump) bottom is a 15B-FTEBut if we are talking in-line FTs vs rotary FTs, replacing the drive gear (and maybe front and/or rear timing covers) would fix that. Or do they have different engine blocks?
