All of the stuff you listed is a direct swap from a 350.Just tell your engine builder what you want to do and go from there.

It's best to start with a new block. if your useing a used block try the find a std bore block. This normaly means it hasn't been rebuilt or atleast never machined.Don't soley on that though.I'm assuming your useing the block in your truck now. Pay the money to have the block checked over buy a machinst. there is nothing worse that building an engine then having to sart over because there was a spiderweb thin crack in it somewhere.

remember this before you do anything. Lighter is better. the less power needed to move the enternals the more power you can make. balanceing is important and needed. titanium is short use metal, so don't get any titanium parts.
.
forged and coated pistons. .20 over max. the coating will help with reduseing detonation. Make sure the machinst goes the extra mile and rounds off any sharp corners on the relifs as well. the corners hold heat very good and will cause detonation as well
the rods will depend on the overall compresion ratio, but get forged.
spend the extra, replase any bolt that requires a substatial amount of tq with quality bolts.the wave lok rod bolts are the best I've found so far. I recomend arp and replaseing the head bolts with studs. You get more acurate and even tourque.

rings:at least molly steel. T-seals are real good rings.

if you find a good engine builder tell him what you want to do with the engine whether it's street, or strictly race(if so what kind of raceing), what your wanting in power, and how much your willing to spend(it'll be no less than 4000 exspect closer to 6g though). Listen to him and get at least 2 outher opinions from builders.
