History: My first love was a '69 Impala SS 427 with a 4-speed Muncie M-22. After headers, cam and Holley, real simple shit, everyone did it without knowing a thing about engines, I trashed the first transmission. Got another from the wrecker and had it looked over by someone in the know and got his blessing. Sure enough, later that year #2 tranny went bye bye. Not fucking around this time, I had #3 rebuilt and blueprinted. Following summer, that one started making noise. Hell with it, I thought, fed up with these M-22 Rock Crushers, replaced it with Turbo 400. Good and reliable but not the same, sold the car.
Next car: '69 Charger R/T 440 with 727 auto. Preferring a manual, pulled the 727 and installed a 4-speed. Loved the 4-speed but even with bundles of money invested in it (about $2,500 back in '77), times were inconsistent, anywhere from 9.18 (my best) to 9.40's. I came to the conclusion, I can build 'em just can't drive 'em, should have stuck with the 727.
I think for the D16Y8 we're going to build, haven't bought the car yet, we'll go with an automatic. Any issues with the strength and durability of the Honda Auto Tranny's? It's the torque I'm concerned about, that's what killed the M-22's not the HP. I'm sold on the cryogenic treatment and will send the internals out for that but is there anything else? How do I modify the valve body for crisper shifting? Is this like the Turbo 400's and 727's?, I haven't taken one apart. What about the final drive ratio. I had 4.88's in my Charger and it got into the sweet RPM zone in a hurry not to mention the view of the clouds. Don't want anything that radical, maybe something in the high 3's, low 4's perhaps, what are the choices. Thanks guys.
