Mopar newbie

First of welcome aboard. :thumleft:
If your looking for dependability such as a daily driver a 318 is the way to go.
If your looking for a small-block street brawler a warmed over 340 is what you want! :D
Disc-brake conversion why would you want to go to small lug pattern?The option of after market wheels for them are very,very limited!TRust me!Your gonna be better off staying with the 4 1/2 inch pattern and just get a disc set-up,there are a couple sets on moparts.com
