Question about cams..... single pattern vs split

IMO there is very little reason to run a split pattern cam. I never look at exhaust flow number. I don't even care what the exhaust flows. I care about how quiet it is.

The only time I run more exhaust timing is on alcohol.

It's a cam grinder trick to do. They think it's tricky. They take intake duration off and then blow the LSA out to make it RPM. It's a bad way to do it.

Either way, they are either adding exhaust duration or subtracting intake duration.

An asymmetrical lobe single pattern cam is what most guys need.


Edit: I also use a split pattern cam on blown or nitrous.
