1966 valiant worth getting a 230 (or 240 can’t remember the numbers)

Yeah I know 4 speed humps are hard to come by and different for 66. Would be interesting if the tunnel floor was slightly different. I wouldn’t count on it but never know with some of these Mopar’s haha.
For a 4 speed conversion, I think you'd just need the 4 speed hump or custom cutout for whatever floor shifter you decide to use. The transmission crossmember is the same and so is the pan reinforcement. They did have an 833 as a option you know, both for the 273 and slant 6! :lol: Mother Mopar didn't completely reinvent the wheel when they made that an option.
