Rear wheel bearings: With the stock 3.2 muffler in place, versus my previous race mufflers, I started hearing a lot of other sounds that I had never heard before. One of these was a droning from the left rear. Turned out to be a wheel bearing. Suggestion to future readers; if your swapping your tranny/axles, you may want to consider replacing the rear wheel bearings while your in there, especially if they are over 10 yrs old. All is well now.

Oil pressure: Compared to my 2.4, this 3.2 has much higher oil pressure at idle and low revs. I run about 25-30 psi at idle, and 60-65 psi at 2500-3000. My 2.4 was close to 0 at idle (not that unusual for an early motor, so I hear), and then 30-40 in the 2500-3000 range. I think both motors are in the 80-100 psi range by 6K. (FYI - I had the cam line restrictors in both motors.)

Lack of power at low revs: As much as I have enjoyed the 3.2 swap overall, the power and drivability of the engine at low revs was lacking. At first I thought it was just the taller gearing. But after more research into the 3.2 DME history/operations, I determined that some changes were in order. I adjusted the idle mixture first. Turns out mine had been adjusted way too lean by someone previously, probably in an attempt to pass an emissions test. This made a tremendous improvement...for free! I also installed an aftermarket chip, which really livened up the throttle response below 3K. I don't want to start a chip discussion here, but again for future readers, the 84-86 3.2 DME has the least desirable engine mapping. You are well served to upgrade to either the 87-89 factory programs, or go with an aftermarket chip, IMHO.

I can't wait to get this car on the track, especially a long one like Road America!
