64 3 sp to 77 4/OD Installation

Wow AJ, you threw a wet blanket on this one. Slim didn't say what
mill he's running. If he's got his stuff together, I say go for it.

I also have a 64 Valiant with the optional "big" 225. I just rebuilt it and got it running last fall. It's 3 on the tree with the standard 3.23 gear. I put about 400 miles on it before winter and it seems to have plenty of power. I will say the column shift sucks. Even with careful slow granny shifting it tends to jam and I have to pull over and unjam it. I'm going to give it another try because I just bought some new shifter bushings that will enable me to get a more precise adjustment.

But....I've been collecting parts for a 4 speed conversion. As luck would have it, I now have both a 65 4 speed trunnion mount trans with Hurst shifter and a mid 70's OD trans with shifter and the Bellhousings for both. I finally also obtained 2 floor humps. One is a 64-65 round hole and the other is a 66 oblong hole. The earlier one is VERY rusty but has the correct shifter hole. The 66 is much better but has incorrect hole.

My plan is to try the 65 trans first as my trunnion driveshaft is in good shape and is a direct bolt-in. The OD would require a new shaft. I'll probably try both eventually just for fun. This car will be a driver (entered in this year's Carlisle) and I'd like to get decent mileage so it'll be interesting.
