Rarity (and desirability) of a slant six/ factory 4 speed?

wow, never thought the question would have generated 3 pages worth of good conversation.

Regardless the car was gone that day before I got off work to go look at it. If the seller was legit, then it was a 17k mile one owner survivor, though the amount of duct tape on that seat makes me think that because the title is original, there'd be no saying if the clock rolled over, and it was realistically a 117k car.

No matter though. I asked more because I wanted to get peoples opinions on slant sixes backed with a 4 speed, and that i got. :)

Personally, i yanked my 225 outta my 65 Dart gt and swapped in a 360 (dressed up like a 273) and never looked back, but if i ended up grabbing this little bugger, i might have kept it quirky and run the 225, just to open the hood and have people scratch heads at the idea that an engine/trans combo like that was even available.

Thanks all.
