    Automatic transmissions aren't my bag, but the AOD in my white coupe was pretty decent. It was a basic rebuild with upgraded clutches and an A+ servo, Silverfox SPT-R (OD lockout), B&M deep pan, stacked plate cooler, and a Dirty Dog 3600-ish stall NLU converter. Rest of the build was a .020 over GT40P headed 302 with an HO cam (straight up), Crane 1.7s, Holley 600 DP, 2.5" exhaust and 3.73s. The car was a nice time and would blast the tires off from a stop; excellent throttle response. Decent around town drivability, and no HO cam light switch nonsense with that converter. I would highly recommend those drivetrain mods to support your engine build.

      first one has a lot of rambling but there is a start and idle bit at the end there. Also get to see a big part of what prompted the cam swap, though I honestly did not know that damage was there beforehand. i just know the engine was getting noisy and the performance was lacking. once it came apart it was fairly obvious why. The rocker arms also got replaced, went from Crane Cobra 1.7 to the Scorpion. no better reason than because I already owned them and they fit under the valve covers. Honestly they seem better made anyway.
