Jeep Strokers

I have a 99 jeep Grand cherokee stock block Clear water big valve head harlandsharp roller arp head studs banks torque tube manifold Eaton m90 sidemount supercharger running 7psi built trans body 4 inch lift IRL short arm kit Aem afi gauge glow shift trans gauge all gauges 488 gears with true trac front and rear 33 inch tire. It’s time for a storocker I’ve always thought I would make it 4.2.quesstiom I really can’t find any information about 4.6 supercharged that lasted more the 20 thousand miles.??

I have very little experience with a stroker but I do have experience with the stock 4.0l with an overdriven m90. Even on 12psi it was lack luster. A turbocharger was a much better option for my application. At what rpm do you achieve 5psi?
