Check out my car and talk to me about 318/340 swap

Don't do it! Just leave the 318. I've said this on here before but ill say it again. When I was young I wanted to v8 swap my slant 6 dart. And a wise old man told me "only a fool would pull a perfectly good running engine" he was right and although I didn't pull the slant when it was "perfectly running" I ended up blowing it up and v8 swapping it. And as much as I love my 360 now I sure do miss that slant six I would love to have another abody with a slant six in it again. Im sure you would miss that 318 eventually too.
