Glad you're making progress. I can only comment of the overdrive. I have a 3.90 rear gear and 27" rear tires. My 2nd overdrive is 0.5 and first over drive is 0.8? or there about. I only use 6th on the interstate. Even then, 5th gear would work just fine. I typically don't go over 4th in the city though the car drives and accelerates in 5th just fine at lower speeds. Personal preference there I guess. Point being, I wouldn't worry about having a six speed. So long as your engine is tuned well, it will run fine in the lower rpms the overdrives will keep you in.

Now, if budget is tight and or putting a 6 speed in a first gen is significantly harder than using the 5 speed, I'd go with the 5 honestly. I had the T56 so there was no question I'd use it. I don't need it at all. Though, it is fun to hear the exhaust noise completely drop away at interstate speeds because I'm scooting along below 2000 rpms.

Good luck.

I went with American Powertrain on my 68 Camaro T56 swap and they’re definitely a reputable company. I actually ended up not using a good portion of the kit including the crossmember, hydraulic clutch MC, reservoir, and firewall bracket, etc. I still have it in boxes. Doing it again, not buying those things twice would’ve saved me a considerable amount but I wanted the install to be more “factory” looking so I went with DSE firewall bracket and a newer Camaro style clutch MC and Bowler’s crossmember. I’ve been very satisfied with the parts and service from American Powertrain. Me personally, for the money, I’d go 6 speed, especially since there’s a strong likelihood that you’ll have to modify the trans tunnel anyway to get the proper driveline angle and keep things tucked up tight. With my setup, at 70mph I’m cruising at 2200 rpm with 3.73 gears.
