Well i have not seen one pro to building a stroker. All that extra work and they just are not making any more power than what a bone stock block can handle. I put down 436 FT LB of torque to the wheels completely UNTUNED. Stock head, stock block, stock intake manifold, stock exhaust manifold. That was pushing 18psi. Now granted i am smart enough to through that Nissan headgasket in the trash and use a Felpro, but other than that we are talking stock. This motor has 145,000 miles on it too. That was a few years back, now i run 25psi completely untuned. Nothing more than seat of the pants tuning with the SDS. My solution for tuning? Nitrous!!! Now i run 25 psi (big hybrid turbo) and a 75hp shot of nitrous. All on a bone stock motor. Now tell me, if a stock motor can handle all this abuse. Why in the HELL would you change it????? Oh and guess what, i have yet to have a dampner problem since i shift at 6500 rpm
