My Cutlass has a 12 bolt Chev posi rear with 3.73:1 gears; I don't want to go higher (numerically) than that. I could deal with a honing for the block. Right now, I'm pretty much stumped on what I'd do for a cam if I took the 455 route. How much lift/duration could a 9:1 455 with 3.73 gears handle and what stall speed would I need for the converter? I'm not even sure if I'd go hyd. roller or hyd. flat tappet; I like Comp, but they don't seem to offer much in the way of Olds hyd. roller cams... which might be just as well, since money IS an issue. On the other hand, I've heard MANY horror stories about flat tappet cams getting wiped out (especially Comps?) during break-in; hence the confusion. Any suggestions?
Thanks for the responses!
