You want to keep a fairly low stall, because it will stall higher with more power, and respond better on spray. The cam is perfect for a stroker and will create an awesome power band, and I don't need to explain the AFR's.

i would stick with 1.7 rockers, and with the larger valves in the ARF you will have to flycut.... Personally i would go with a little smaller cam so i didnt have to flycut if your going to be on the juice. Just my .02

They like to keep there cam specs secret. I wouldnt buy a cam with out knowing them, but with a little time searching on this board you will find them... If i remember correctly G5X series cams are gound on a comp X-ER lobe, but i dont remember the specs... i do know that the g5x4 is not much bigger than the g5x3... I think its like 2 degrees more duration on the intake and exhaust thats it... Also how big of a shot do you plan on running? Because below 200 shot cam selection wont be that big of a deal

Fly cut is a relief (a notch) in each piston so that there is no contact between the piston and the valves. When the valves open, they lower into the cylinder, coming closer to the top of the piston. This is bad...very bad.

i highly doubt you can run the x4 in anything but unmilled and with stock valves... you might be able to get away with the x3... correct me if im wrong

if your goin to build a stroker engine at the same time as the rest of the mods, then you wont have to worry about flycuting the pistons. Im pretty sure good pistons will come with a oversized relief in them already, wont they? I know my stroker pistons (LT1 383) are dished AND have big reiliefs in there.
Im curious what you guys think would be a good rotating assembly for his LS1 engine that can handle 9s on spray.
