The gap may become a plus depending on transmission, I'm lost in that regard. Porsche 901/902/911/914 seems ok, but a lot of work for little gain, closer gear ratios, yes. The goal is high to extreme reliability, I like building, but once built I wash and detail it, do regular maintenance, but no more wrenching.

Transmission, that Berg Bus 5 seems very attractive .. much stronger than a 901/911 .. but I wonder how it compares to a 915.

G50 is an option, I have used 964 C2 boxes that could be converted to a short G50 by using the nose cone of the short G50, shortening like Wally did. 930, but my motorcycle heads are not going to produce huge amounts of torque (although we can bring the 8000 rpm torque peak down a lot).
