Interesting thoughts and observations on OD transmissions
Yeah, 2000 rpm makes sense. Assuming a 26 inch tire, the math says you're at 2050 rpm at 65 mph when after the converter locks, so probably around 2300 under light acceleration at 65 mph. Is your torque converter stock?
Those 3.55's must be nice! The 3.23 is way low (high?) for me, but I just picked up another center section and will be putting in a set of 3.73 gears.
I would love to see a video. Maybe I'll get my car out tomorrow and do a video too (it's raining today).
Yes, stock converter (1800)
The 3.55 gears with the low first of the 42RH makes things pretty fun in town, though I did twist a driveshaft in half and had a stronger built.
OD with lockup gets me about 2,200 at 80mph.
The cam from Oregon Cams was selected and ground for good torque.
214/224@50 with .512 lift and 110 lsa for a little sound.
I’m running a Holley 770 Street Avenger, vacuum secondary and electric choke. (With some light mods)
New Zealand EQ heads, 1.92 valves and LA style intake mounting, Hughes 1110 springs with the retainer and locks kit that allows the .512 lift without running into the positive style stem seals.
I have a 8.25 1973-4 A body diff with a Dakota limited slip that bolted right in with different carrier bearings, and the factory Dakota disc brakes that also bolted right on.
I did have to add longer wheel studs due to the discs being added.
