Rocker Geometry!

those rockers are steel right , and there weight over or under the alloy t&d's . steel ones seem more bullet proff . should i make my own shafts from heavy wall chromol tube or are their shaft good to go as well . i'm building a 470 ci stage 6 alloy chapman mw port'd n flow'd by dave story in ky . mw twin fours new mopar intake match'd pair of 750's . good rods n pistons , run some street , some strip . spiro jannings of redline cams is grinding my cam , he has ground cams for dave that would turn'd 8800 on a truck pulling wedge made 808 hp on gas one carb . i'm not thinking that number , not buzzing it that number just 75-8 in a super stock set up 63 fury . so my point is nascar over nhra built race engines . with the old school look .
