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

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.

I'd go with someone fairly close to you. No matter how good the rep,
something can go wrong with a tranny from any builder. 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.

Getting tired of pushing the clutch and shifting gears with the
Richmond 5 sp. 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.
