340s that lunati 305 for big blocks really rocks for a hyd cam, ramps faster than any other hyd cam ive used,the faster the valves open and close the better . specs are .533 int. .552 exh 242 duration at .50 int 252 on exhaust, very sweet street cam for big block also, actually best ive seen, nice choice this cam will outperform the mp .509 all day and night long
