Yeah Greg,basically that cam runs out at 6000rpm,but I`m hoping to get another 200 out of it by retarding it.The intake closes at 71 which is very good for cylinder fill & with the xtra lift from those rockers it may work better than I think.The mtr has 10&1/2 to one comp,victor jr intake & Roush 200s with port match,bowl work w/ guides cut down,2.05 unshrouded valves so its going to get plenty of air,so it is not going to be a pig.
