lead, the lunati cam is not much bigger would you see much difference there . i was thinking 513/533 hyd. cam or bigger.
The suggestion is for the combo your running right now,either of the cams will definitely make more power than your current grind-even with no changes.To run anything bigger you need some compression to really take advantage,you have to make some tough decisions where to spend the remaining $1,400.If you get in the bottom end you could eat most of that up real quick if the bottom end isnt fresh already,pistons balancing,then you open up the can of worms with the condition of the short block-rod bolts/clearences ect,especially if the engine has some miles on it.If you just want to get er done with what you have mill the heads,use the mp p4120094 head gaskets,have some port work done and then go with the lunati voodoo 60404,thats what I would do lol.
