Ok, so if you wanted to do a completely stock factory type of rebuild of a 2 barrel 69 318, whose pistons, and cam would you use?

I'd use pistons without holes, or is it whores?

Course my wheel barrow doesn't have a 318.

To answer the question, a complete factory stock type rebuild would use factory pistons and cam. Otherwise it's just a generic rebuild of the aftermarket type.

For a basic stock rebuild,low cost replacement parts are adequate.
Sealed power pistons and rings will work.
If I were you I would step it up a little since you are that far into the motor,more compression,cam,touch up the heads,etc.
The motor is getting old,most likely needs fresh valve springs.
Oil pump is a given.
What is your goal and budget?

cheapest would be a basic rebuild kit/Summitt cam. next step up ($$$$) would be some 302 or mag heads & some hughes plateau pistons & additional machining to get quench for an efficient long block. You're only working with 318 cubes & what is the weight of the vehicle it is going into?

This is a 69 B body with auto. It's a 4 door. I looked at Sealed Power pistons once, but hell they weighed more than the originals. Extra performance is not the goal, but I do want the absolute smoothness, and quietness that the engine had when new. Yes, everything else will be new, and the 2 barrel will be going back on it also. I was wondering about brands for quality.

The bobweight ain't an issue in your case (wont affect smoothness) unless you want/need the new pistons to weigh close enough to the OE ones so that you do not have to rebalance & you do have some leeway there (HF has a cheap digital scale on sale regularly for $10) I would suggest the cheapest rebuild kit you can find (with a few add ons) (pistons/pins/plasma file fit rings/rod/main bearings/cam bearings (maybe)/cam/lifters/gaskets/thin composition head gaskets. tweak the carb/dist after you get it running. read "breakin secrets" at www.mototuneusa.com it'd definitely be a plus if you could bump the SCR with some closed chamber heads or expensive pistons

I would think you need to refurb your heads. Might as well step them up with a set of 302 heads. Mid 80's, plenty of info here on the boards about them.
