Funny thing Oliver- that was the first 110 I built from scratch, and by far the best powertrain. We adapted it to the ZF auto- a fella in the UK built adapters, but cannot put my hands on it now. I am doing a new SBC in the 130 only because it had already been started that way, otherwise it would be the Isuzu- largest diesel manufacturer in the world!! And who GM went to for consultation on the Duramax. If you remember David Gage @ Thatched Roof Garage- he is who got me tuned on to Isuzu, and he had done many of them. They flat fly for a small diesel, and return fantastic economy, and all mechanical to boot. Geared in lieu of timing belt- just waaaay robust. I was a bit afraid of parts availability initially, but really not a problem, and Chevy dealers can get most items since they shared their box truck diesel with the NPR back in mid 80s. Bottom line, as I said earlier- SBC if gas, but must say if diesel, Isuzu for sure. On a side note, Robt Davis is about done with his adapter to the MB diesel as well as modified oil pan, etc... Sorry to ramble- been up two days and fading fast- cheers
