So I have this newly inserted Model A engine in the car and running. Seems to do fine, though I haven't put any real miles on it yet, probably five. I heated it up good and rechecked the torque on the head, 50 Lbs all around, nothing changed. The last rebuild I had was stock babbitt and I suppose the inserts mean a bit or change in break in strategy? I'm considering a haul from Danville, CA to Boise, Idaho, then an oil change before returning to Danville. I have a Mitchell and am thinking or backroads for starters then easing into the Interstates at 45/50 if traffic will allow me to go that slow. The speedometer is right on with my GPS and I'm running 3:54 rear end and 16 in tires, which Mitchell tells me is the same as stock 3:78 with the 21's. What is the thinking? I have an oil gauge that shows 35 psi when warm. I plan to change to Rotella on my first oil change, 10/50.
