360 with the 509 cam

Me too. If 340-8 doesnt have your grind of choice, I got a Crane Powermax H-278-2 (old HMV-278-2-NC part number) trade you straight across, keep your new lifters.
great or sick minds think alike lol.i was thinking that would be a good choice for his set up as well,and ive got the hmv 278 on the shelf.i just was not willing to part with it just yet.the mopar purple 268/272 450/455 110lsa would work good too i think.
