I have a 59 thunderbird (6t) which is the lower performance model, in looking to put high lift cams in it. I've been looking on theis site here,

http://http://www.johnsoncams.com/jc_t_cams.html

I like the sifton 390 cam which has a .352 of lift, i don't want to go to crazy, but I do want some more performance. Does anyone have any experience with high lift cams/knows the best ones to get? Also, the guys at ace classics London advised me to run 7.5:1 pistons, for reliability, but can not for the life of me remember what cam grind they recommended.

in my opinion, bigger cams (and cam timing) are just one part of building a performance engine and the cams do no real good without the other things like high compression pistons, bigger valves, better carbs.
