How do you know which cam to use for different setups as far as bottom end torque, mid, or top speed? A-9 A13, A-this A-That A-What?  |

A9 is the top speed cam a13 is a torque cam low number is top end less torque high number torque not top speed

Good question, it would have to be dialed to find out.

I think higher the number higher the lift so the valves will float a little at high rpm producing less top speed but at low end and midrange the higher numbered cams are awesome. You need better valve springs with cams a12 and up is why I got an upgraded head. I love the take off and torque from my a13 cam and my top speed is still good but it does make the valves noisy regardless how tight you set them the higher lift opens more which causes the valves to slam down on the spring

I didn't see anything about camshafts on that. It would be nice if there was a chart that list all the camshafts and their numbers and performance curves! |

You can go with the high lift a14 cam its supposedly the most aggressive I just went a step down from it so I didn't lose top speed

Yeah, read more toward the bottom of the page, he talks about lift and lobe separation angle. He may have gone into more detail in another post, But I couldnt find it. Anyway, He's knowledgeable on cams. He has dialed a few. PM him and ask. |

Mines a torque monster with the a13 wonder what a14 or a15 would be like probably throw you off the seat lol. Only downside is noisy valves have mine set at .003 intake .004 exhaust and they still are noisy.

No extra gaskets and no issues at around 1000 miles
