Oil pressure is 20 at idle, and ramps up by 10 for each 1000 rpm. Vacuum is at 12 or 13 at idle. Idle is set to around 700rpm, and that gear drive sounds pretty cool (but I don't know if I'll keep it).
I decided to 'use whatcha got' on the exhaust- and once complete, there will be four harley slip-ons (baffles punched out) hanging out under the rear bumper. I'm using 2" pipe. I should have gone with 2 1/4, but that's what I had on hand.
I've also completed the engine bay wiring harness - I need only to pick up a few weatherpack connectors to pass the wires through the firewall properly.
I'm quite pleased with the progress so far.
