440 Build Help...Piston Delima

Dont fret about your pistons too long or overthink it,aint a damn thing wrong with the 2355's,they can be lightened and are bulletproof and for a street/strip engine build are hard to beat,have the engine balanced and you will never ever know the difference of a few grams,you aint building a piano here...these 2355's would and still is my choice of pistons for many reasons,in fact I'm looking for a set now in std bore for my 440 with 906[77cc] heads and a comp solid 290 cam and plan on running it on pump gas[89-91] final comp should be around 9.6 on mine..only if your planning on a 600hp plus monster then I would prob look at a lighter piston or spend the x-tra money...call it oldschool or whatever it works,and it works good and has been proven time after time as a outstanding performer and they still make them for a reason...so for the street/strip version a flat-top piston[with valve reliefs,like the 2355's] will serve you best and be easier for your build and can be improved upon in future upgrades..as far as cams go I would go a step or 2 above the 268 but thats just my opinion the 268 also performs well also...good luck with your build and keep it fun...
