chrysler 3 speed manual dodge rv 360 Swap

What kind of three speed? There are a few versions and I would only use one behind a V8.
Hey Dude. It's a 230

These other numbers I took notes from it last summer not sure what they mean

3B383762
PP2304233
I did some sort of decoder on some site and got this

First Line
(3) = 1973 year
(B) = Hamtrack Built Vehicle
383762 =VIN Number

Second Line
PP = New Process Gear Division Plant
230 = 3 Speed Manual transmission
