Default What does it take to hit 120hp

I got a 103. I’m buying a 110” big bore. Hammer head performance “Smash” heads. 58mm throttle body (brand in the air) 5.3 injectors, 585 cams, hydraulic lifters, pushrods, still thinking of a fueling chest and pump cause they claim 3hp gain I know it’s not a lot for 700$ but 3hp gained is a gain. But with that setup is it possible to hit my 120 goal if not what else do I gotta get to hit me number

You only looking for a peak number, or a broad usable torque curve? I would recommend going to Fuel Moto’s website and looking at their dyno charts. Their level b heads, 107 kit and a proper cam choice should get you there with a good tune.

wont get 120 HP on a 110 with a CR 570 cam. The cam will need to be bigger.

well uts gonna be 110 with comparable head work just different people still around 800. But like I said 585 already ordered I’ll be mad if I don’t hit that number even with a 58mm and injectors
