Default Federal-Mogul lightweight pistons questions and specs

hello all, i have a nos set of discontinued lightweight federal mogul pistons with the part numbers of lw5020f and lw5021f. they are small block chevy pistons for a 383 stroker . i have little info other than the weight (448 grams), compression ( 10.5-1) and that they are 2618 alloy. if someone has an an old F-M catalog i could use some info like valve relief cc's,piston to cylinder clearance, compression height etc. i am building a new motor for next season and could use the info. thanks in advance for any info. gary
