318 Magnum pistons and rods in an LA motor

yeah the FW and damper are neutral on a 318 but with all new "other parts" in the mix it definitely would not hurt to have them checked along with the parts that yuo plan on using. I'm puttin together a 318 Mag as we speak that I hope to get an honest 300HP from, and I have another 318 Mag block here that I hope to turn into a 390 down the road.
