Engine rebuild choices

Im building up a 318 for my dart, its not going to be high performance, but it will be above stock, and im looking for suggestions/answers for it.

I guess the first thing is, i will be using it for a daily motor, on city streets, the highways (everyday, and long distance up and down the west coast), towing a small camp trailer, and to be able to smoke a honda if the mood strikes me. :burnout:

I have a 318 from 1972 that came out of a 1966 charger. it had been sitting since the 80s with one owner, its a stock motor, with the two barrel intake and factory manifolds. I have a forged steel crank for it. I have a set of eagle headers that i am using for the motor, along with an edelbrock economy 4 barrel intake, and a thermoquad.

Right now i have a perfectly good running 225 slant in the car, so i can wait a long time before installing the motor. I work intermittently, so i cant get high priced parts, but i can save for important, quality parts.

I need a suggestion for pistons, for a good cam, lifters, a good header gasket and whatever else anybody can think of.

Heres one of my questions; what type of piston rings should i use, i've read that chrome rings are good for a dirty environment, but also that for my motor, iron rings would be best.

Thats my only question now, but i'll have more later.

I have built a couple motors before, but not one from a stock like this, so any help or suggestions will be appreciated.
