Wasting your time for sure, better sell the P3s and buy some tuner 2s

The most cam I'd go is something along the lines of Pro2s for that setup.

The most common mistake I see is people throwing way too much cam at a motor.

As suggested, Skunk tuner 2s, or Blox B or Cs would be a good choice for this motor.

LOL that didn't take long.

I say check your clearances and if needed fly-cut the valve reliefs deeper and take a chance with the pro3's. Honda-tech is full of "What should work theories" but sometimes you have to take a chance and you might just find out something interesting.

Obviously, the combination of supporting bolt-ons will play a huge role here too.

i know what should and should not work that is not the problem. engine is already running with pro1 intake itr exhaust cam. i know it is "over camming" but they are not selling. so if i clear p2v fine then i would run them aswell as try different exhaust cams. With that said if i could sell them i would be dropping in some cams from ddtech most likely. So hopefully Some Of the Builders with experience with using pro3s on smaller engines can chime in and i know there are a few (rip donf).


also this is the profile i think this setup will end up liking

pro3 intake .500 270
custom crower .496 254
