You've done most everything I plan on doing to mine for my 1970 El Camino, except I'm only wanting 400-450 hp. I've been eyeing those 4BT hydraulic pumps for a while, but haven't jumped on one. Good to see it is possible!
I don’t. As far as I know you can only get them off of 4bt Cummins applications. Some people made aftermarket ones but they stopped from what I know. Best bet is to find one used.
Man i loved how you guild though on 5.9 cummin me myself im new with cummin thing learning how's system work and close up visual how you did that give me idea alot. i wanted see more about 1st gen build!
