I'd want to know what gear I had currently- sounds like you have a low (high numerical) gear in there now, or a very loose torque converter.327_79malibulandu said:
If you don't have a rad cam, you could get by w/something like a 2.73 to 3.23 rear gear. Highway friendly, but offer some acceleration.
Ratios as high a 2.29 (Edit- 2.14 in '79) were available, but they are stupid-high, IMHO.
Available OEM ratios for the 7.5" (and were also available in the 8.5", 2.41-up, IIRC) diff include:
2.29, 2.41, 2.56, 2.73, 2.93, 3.08, 3.23, 3.42, 3.73.
Another option is to keep the steep gear and swap the transmission for a TH700R4 w/OD.
Good luck.
i do have a big cam in it atm but i looking to get a 3000 stall or a 3500 stall but im im useing a 2500 stall. i recently changed motors i had a 327 tilll the wife blew it up so i installed a 350. i cant remember the cam specs i can get them posted later gotta find it
Big cam w/high gears won't be a happy combination.327_79malibulandu said:
You might seriously consider the OD transmission swap. You can also use a lock up TC, takes a aftermarket lock up switch. In your case the transmission to use would be a TH700R4. It has a .7 overdrive, so a 4.11 rear gear becomes a 2.88. Very highway friendly.
I'd say a 3.08 with a TH350. The cam isn't too big if it's that HE 268 in your sig, and a 3.08 won't put you at too high of an rpm on the expressway (26" tall tire with 3.08s will be around 2800rpm @ 70mph, 2200rpm @ 55mph).
Agreed. Personally I'd go with a 2004R, 1st to 2nd gear isn't as much of a drop as a 700R-4. I'd probably go with something like a 3.42 though. With the 4-speed I have and 2.29s the ratios figure almost identical to a 2004R with 3.42s, and with ~375hp it's hard to keep the tires from going up in smoke in 1st gear.cobalt327 said:
I'm with you. I didn't consider the OP had a 268 when he said "big cam".Doober said:
The only reason I gave the nod to the TH700R4 is because of the lack of a computer. Obviously there are boxes that will allow him to use the TH2004R in a non-ECM app, and I personally like the 200 a little more than the 4L60E. But if there are budget restraints, I'd go w/the 700.
3.42's would be my limit, for sure. My poor ol' wagon has those dreadful 2.29"s, too. Soon to be remedied, along w/a few other little details (engine, M20 swap, tires and wheels, paint... lol).
my wagon had 2.29s in it i went with a 3.42 it was like swapping a new powertrain in it .performed well and decent milege also..also ran 16in low pros
