Good Morning. Have a R700 with a 1984 305 Camaro and a 1975 3.55 diff hope it is going to give me good economics. All this has been fitted in a 1975 South African Sport Sedan. I have a 3.36 diff that I can fit if needed. Would appreciate your thoughts Johann W Grobler Retired ----- Original Message ----- From: Chuck Hanson To: The Chevelle Mailing List Sent: Saturday, June 19, 2010 7:02 PM Subject: Re: [Chevelle-list] 700 R4 Trans
Good advice, Rick. A reputable local trans shop is the way I'd go, too. Ditto on your gear ratio selection... The 2.73 won't cut it with the overdrive trans. I had 3.08 gears in my '66 wagon w/700R4 trans, and it never was in its "sweet spot" while cruising @ 70 mph. Changed to a 3.42 and the motor is a lot happier, plus mileage picked up about 1.5 - 2 mpg to boot! Since less throttle is now required to maintain any given speed, I had to reprogram the ECM for my Holley FI system, but it was only small tweaks in the light cruise mode.

And then its a pain ($$$) to ship back & forth for repairs. In the Dallas area I know both Phoenix Transmissions & Jakeshoe are reputable builders. And I've heard lots of good about Bowtie Overdrives in CA. So where are you located would be a good thing to know. Also with 2.73 gears and overdrive you'll be cruising at 1200RPM (more or less) - probably not the sweet spot for most motors. I am running 3.31 gears and cruise right at 1700 RPM - 3.73 would probably be better for me.

The shoulder is starting to hurt. The 5 speed is a great transmission. Totally bullet proof. It has been a great combo with the 2.73 gears. I think it is time to part with it and go with the 700 R4. Does anyone have a recommendation for a good source. The ol BB has about 500 hp. No racing. Will be looking for a home for the 5 sp. The shifter is a Hurst. Larry -- Rick Schaefer 72 TPI El Camino
