Cams How do you choose one?

I can tell you that you will feel/notice .25 point in DCR right off. It will show up in throttle response driving around. But won't go from doggie to blazing. More and more DCR will make it go more and more torquier at low RPM's.

All the DCR's above are at least higher than stock 318 so that is all good.

I personally like the Howard's 3rd on the list. Darned good lift for the duration. That all relates to the area under the curve.... you can have long duration and lower lift (but the later ICA hurts low RPM torque.....i.e., low DCR) or have high lift and low duration and less/no ill effects on the DCR.

I still laugh at that guy you ran into with the cam selection problem in post #79 LOL

BTW, the term you need to use is ICA (not ICL) which is the intake closing angle. ICL IS pertinent.... as is works into ICA. All of the numbers that you are getting from the manufacturers are probably with the cam installed 'straight up'.... i.e., with the timing chain sprockets installed 'dot-to-dot'. ICL (Intake center line) is the 2nd number in the number pair like '112/108' wiht the cam installed 'straight up'.

You can advance the cam's timing to something less for ICL, and that reduces the ICA by the same amount. I.e., advance the cam's ICL timing at installation by 4 degrees, like from 108 to 104 and then the ICA goes down by 4. Low RPM torque goes up (as does DCR) and the top end RPM peak HP goes to a lower RPM, and typically a bit lower peak HP. So playing with the installed ICL by advancing the cam is another thing to play with.
