The pistons appear to be .005 below the deck. They also have valve reliefs but i cannot be too sure how many cc's they are. I have no idea what the CC is on "J" heads vs my stock magnums anyway. My magnum heads already have the "R/T" springs and titanium retainers.
Anyway, I think the XE262 is too mild for this application. I'm running rather short tires of less than 26" with the 3.23 ring. I currently have a hotter cam (summit k6901) in my very low compression 360 and that has good enough street manners.
I'm thinking the XE268 would be as low as I would go. I might stick with the purpleshaft even. Its not really a daily driver car anyway.
Why are you looking to build the 340 instead of your 360? With everything else being equal, I'd think the 360 with Mag heads would be all over the 340 with J heads.
