Yes,the 265 was only available in a two barrel. Same # 3731548 block but smaller bore.
No they should not allow 4 speeds(manual) in stock. Blasphemy I say! Besides you have to do some real hanky panky to make the shifter clear the original bench seat. Whats next bucket seats in stock.

The stock 10 bolt rearend would not be a good choice. They are very weak and I doubt if pro gears are even available anymore. They only came as low as 6.17 and had 6 teeth on the pinion. After a couple of passes they end up with zero. I believe the yoke is a 1310 too.

My choice would be a Mark William's 12 bolt with as low as gear ratio possible and big wheel studs.
Transmission would be a Jerico DR-4 (although they no longer sell them new) with a 3.08 first,2.10 second & 1:1 third. G-Force would also work. You can underdrive third on them.
