700R4 in a Second Gen. Camaro
If have not already, do a search on this board. Plenty of stuff regarding the 700R4. In fact, the first thread in this tech section by M&M CUSTOM is about this trans:

I swapped a 700R4 into my 81’ Camaro about 8 years ago. Back then, there were not many aftermarket sources to help with this swap. But now, there are many different sources. Whatever route you take, you will need to cut the driveshaft 3”, move the cross member back 2”, and get an automatic 4-speed shifter. A TH350 yoke will work with the 700R4.
I would recommend you check out
www.bowtieoverdrives.com . Besides selling different levels of transmissions and converters at competitive prices, they sell every conceivable part to make the swap a “no brainer”. They sell custom cross members that will eliminate the need to drill new holes (if your frame does not already have them). I had to drill holes and it was a real pain. Probably the most important and most overlooked aspect of a 700R4 swap is the TV cable. The TV cable must be set perfectly to assure proper operation and transmission longevity. They have custom brackets and cables for a wide variety of carbs and fuel injection systems. Do not be fooled into buying a “click” style TV cable and a universal bracket. The geometry at the throttle and TV plunger relationship to throttle position determines proper operating pressures. Bowtieoverdrives has a very detailed section on TV cables (how they work and why getting the relationship correct is so critical). They also sell electronic lockup kits that allow installation into non-computer controlled vehicles.
I installed a non-lockup 700R4 in my Camaro so I did not need the conversion kit. With a 4.10 rear and 28” tall tires, I run about 2450 RPM at 70 MPH. With my 385 fuel injected SBC, I get about 18 mpg. You will not regret the swap.
Regarding the off the line punch, there is plenty of it. With a 3.06 first gear, it pulls fine.
Good luck, Ed.
