Have the old crank magg'd and have its old journals cleaned up and checked. Then have the entire rotating assembly balanced. Flat top pistons help with air flow better than domed pistons. CC the heads and get an idea on your compression with either a set of flat tops or domed pistons. Get the steel timing gears. Basically the 300 has a completely bullet proof bottom end, and again you don't plan on revving this motor to the moon so forged pistons probably aren't needed. Make sure to get a good set of moly rings. I like Speed-Pro.
