I don't know of any kits, but Pontiac motors will interchange from '55 to '57 1/2. I don't have any intimate knowlege of '58 and up.

If you're ginna reuse the old 55 slant-pan hydro, [a very good move] you'll need to take your favorite 4" grinder to the later crankshaft flange to remove a little of the sharp edge on the outside of it. Otherwise, the front half of the fluid coupling won't fit flush against the flange, causing a leak [the coupling hasta fit flat against the crank to seal] and a wobble that can take out the frontpump of the hydro on start-up.... sounds scary but it's not..once you try to fit the coupling against the crank, you'll see what I mean. The entire operation can be done with a grinder in about 10 minutes and won't affect engine balance unless you're gonna spin that poncho to about 10 grand...I've done several of 'em this way....
The rest is a bolt-in that can make a holy terror of your mom-and-pop 55 mildmobile... Just imagine! 303 hp of 1959-60 poncho motor where 180 usta be. When you plant your right foot in this setup, you better be ready....I've chirped all 4 gears with this setup and the shift to 2nd can be an adventure all it's own with potential 'curb-to-curb gyrations, complete with mucho carb, tire and exhaust drama........it's fun-city with a lightweight cheiftain 2 door sedan.....
