ZR1 is a totally different engine. 32 valves, 4 overhead cams... etc. If you really want more power from your L98, then the 383 build-up would likely be the best bang for the buck! Lots of folks claim 350+ horse power from the 383 kits.

Youll need to upgrade everything north of the pan to the intake, it wont be cheap. Do a heads/cam/intake upgrade and a solid tune, call it a day. That will set you back a few grand easy; nothing wrong with a stroker motor though youll love the torque but the price of admission isnt cheap.
