@@Op1zilla zx 1000 kawasaki dyno it at 167 at the wheel. Added + 1 mm intake and +1 mm exhaust valves throat bored pockets ported head got biggest intake cam that will fit without machining cam caps had custom made exhaust cam added 80 thoudands lift few more degrees of duration. Again can't physically fit larger cam without machining caps. New main and rod berings 800$ wrist pins .cp corolla rods & pistons. Definitely hope to see 200 to the wheel won't be mad if I see more. Thought you ment small block Chevy but wasn't sure also put all new ceramic bearings in transmission. Set ring end gap so can run about 100 to 150 shot of nitrous. Without failure if it makes 200+ all motor. He could run a progressive controller for nitrous should have zero issues with 275 to 300 to the wheel.
