Some of us have access to enough computing cycles to map intake port velocity, for any given engine size, through any size venturi and throttle bore, for any given RPM, under any operating conditions. Without sending a signal out of the room where I am sitting right now, I can utilize 27 x 10^12 floating point operations per-second (twenty-seven teraflops), although I would probably get in trouble if I used them all. I don't need to get out of my chair to prove some people wrong. If I farm the job out to the DC upstairs, I can get 2 x 10^15 floating point operations per-second (two petaflops), but, when caught, I'd get fired.
forget it, I promised I wasn't getting dragged into this bullshit fest, I'm not. OP, check the link I pm'ed you, then go back and read whats been posted here about how the lock up clutch in the converter supposedly "works", and figure it out. Its pretty obvious. If you want more links/info, let me know. Outta here.
There's a 6 pin planet gear upgrade for the 700r4 that changes the gears to 2.84 1st, 1.56 2nd, 1.1 3rd, .70 O.D. 4th.
My Belair wagon is running a built 700R4 with 4.11 gear and a 28 inch tall rear tire. RPM's at 70 are 2417 and enough gear to get that barge going off the line. You have to build them how you are going to use them.
I am all about driving stuff so I say go with OD so you arent spinning the piss outta the thing when cruising. The thing most forget about the 700R4 is that you get a lower low gear so that means more burn outs.
Drove a 69 Camaro with a 427 with a tunnel ran and 2x 4 barrels and a 4.11 gear with a Muncie for years. 3200 at 70 mph. Just changed the valve springs every winter. Ran a 580 lift cam. Didn't need a radio just listened to the hooker side pipe headers. Drove it from Colorado Springs to Detroit like that. It's a hot rod or a Camry ,make up your mind. Drove a 327 64 Impala with a 4.88 4 speed. Never worried about it. Just kicked store bought muscle car ass with my junkyard survivor.
I ran a GM 200-4R out of an 86 Monte Carlo in the car in my Avatar...9" 3.73 rear. Turned 11.88 I the 1/4...NEVER had problem 1 with it. Out of the stoplight it was a KILLER...FWIW
I run a 350 with turbo 350...31" tall tires....80 mph at 3000 rpm.....drove it to LARS and back...4000 miles....we ran 85-105 across the desert and had no problems with AC ....15 MPG +-.......if your engine wont handle 2500-3000 rpm all day....you need to build a better engine......I put same thing in all my cars.....Took 700r4 out because it wouldn't hold up to a mild 350 in my '32.....this is the car I drove to Pomona with this setup........Some people get me though...they spend all this money for overdrive and brag their getting 22 mpg....but never go anywhere other than local Cruise Ins......if you can't drive them, get rid of them......
Running a 200 4r for 7 years now on my SBC Rod....In AZ you have mucho highways and cruising at 73 mph is a norm, unless you are on 17 N when 85 is norm. That OD is a requirement or a long 4 or 5 speed manual. In OD 70 mph is about 2k rpm the way I'm set up. I also get about 25 mpg cruising even with brick like aerodynamics.
