200 4R Install Questions.

C300 said

Had not been on the site in a while. See that lots are going with the 200 4R. Talked to Art Carr years ago about these. Had issues with one in my Monti SS Aero Coupe. Ended up just the TV cable bracket letting the cable "pop out" when really hot (in AZ.) Cheap fix, Expensive problem, as a rebuild needed every time. so i have one in the garage as a spare. I read the info about building, need a Stage 2 most likely. '67 cuda 512 ci tall block, perf. RPM heads n M1 port matched, Roller cam. Should be mid 600's hp n torque say's Hughes. RPM not much over 6k, dana 60, mini tub, caltracs. willwoods. have a rebuilt '67 a-body 8/3/4" 741 3.55 posi n 727. was going this way. looking for street cruising weekend 1/4 mile car. beat up new GTO's n Mustangs. need the OD for that...
Questions are, best gears. have 4.10's now in a narrowed dana 60 510 housing. 4.56-4.88-5.30 ? I did the calculator. want real world experience.
What's the best adapters, and who makes them ?

I used a bellhousing on my install. I like it much better than the plate style adapters. Also, I am running 3,91 gears with 275/60-15's, a 3000 stall converter with a 3 carbon fiber disc lock-up clutch. Art Carr doesn't know how to set up a lock-up converter in these transmissions, so I skipped him and went with an Extreme Automatics Stage 2 build. The gearing is perfect for long distance cruising and hot street action. It is truly like having a 5 speed automatic. The lock-up is set-up to engage only in 4th gear when I have the toggle switch activated. It automatically unlocks when the transmission downshifts. It an awesome feature. I got 18 mpg at 80 mph on the way home from LA.

I don't think my car would have out pulled a Hellcat in the Spring Fling Drags if not for the 200R4.

If I was bolting one of these to a built big block, I would use a Stage 3 from Extreme Automatics. The bellhousing method of attaching these transmissions makes for a much cleaner install. US Cartool makes the crossmember conversions now, and I would supplement that with their complete chassis stiffening kit
