Hi Guys, I just recently bought a 1968 dodge dart as a project car. It currently has a 225 inline 6 in it & I want to swap it out with one of the 383's I have. I'm new to all this & would appreciate any advice I could get. Main question I have right now is, can I use the K member that is currently in the car or do I need to swap for a big block. Car is a 2 door post & all there. Just needs a lot of TLC. Thanks Guys, Faulbio
