You have a fresh eng. I would max the things you mentioned and related systems. A good dual plane intake tho the iron OE 360 4bbl one is actually a killer piece but heavy iron. Not sure what carb to recommend. #1 would be the right cam choice. then spot on dial in the ign system. initial/total to 35/springs/then the can in order. I would find out if you have open or closed chambered heads & alum heads would be lighter of course & likely closed chambers which you (likely) need but they are pricey & iirc there was a discussion on this here recently & no bennie just from the alloy was the concensus (iirc) so not sure if they would be worth it to you (cost vs bennie).
