Slant six flywheel for manual trans

omotz said
So I pulled the engine and transmission from my 63 Dart and have an engine from a 64 that I’ll be using. I don’t know what year the motor is. I’m assuming it’s a 60s era motor. I measured the flange on the back of the crank 1.9625. I drove the 64 before I pulled it apart. Motor is real Pepe but I’m sure nowhere near 400 hp. I want to put a four speed in, but I don’t think that I can use my three speed bill housing, correct me if I’m wrong. I’d like to buy one of the older A-833 transmissions, but I guess they’re kind of rare. From what I’ve been reading the A-833 OD trans has basically same ratios as a 3 speed with overdrive 4th gear, and they don’t shift as quick as the non overdrive trans. Don’t think I need a clutch that beefy but I’m sure I could be wrong. This car will be a rat, driver, as low buck as I can get it but no junk under the hood………car.

Since you have both engines, just measure the crank flange diameter to see if they're the same. Check to see if the crank you will be using has been machined for a pilot bushing, or you will either have to machine the pilot hole to the correct diameter, or, get a pilot BEARING that fits in the converter register hole. Both sizes are available once you find out which crank you have. Yes, you need a 4 speed bell housing....one that matches the car, and also the transmission front bearing retainer unless you want to do some machining and clutch linkage work. If you have a clutch rebuilder up there in Sacto, have them build one a bit heavier duty than the stock one....maybe build your old one with more or heavier springs. Don't get too carried away though, or, you'll have to beef up the Z-bar and the rest of the linkage. I'm surprised you find the '64-5 833 transmissions hard to find. I used to have a hard time selling them except to some that just wanted the low gear set in them. When I closed the shop, I think 3-4 of them went over the scales as I couldn't find a buyer. Everyone wanted the slip yoke type.
