I have been reading camshaft's lately and I keep getting stuck on one thing. Would a big duration split (Exhaust duration being a lot longer or farther away from the intake duration #) be better/worse than a smaller duration split cam (closer exhaust to intake split) at making power on a N/A motor and why?

Example: The EPS "All Motor" camshaft line have HUGE Split's (12+), while other company's maybe have little (6 and under) to no split.

It might be a dumb question but I really wan't to know.

It greatly depends on your supporting mods and purposes for the car. No one cam shaft is better than the rest. Your head flow characteristics are one of the biggest factors.

I will say Geoff from EPS has designed cams for some of the fasted naturally aspirated cars in the country. You'd be best off to give him a call and maybe he will explain his reasoning.

ive also noticed all these huge split cams as well. I believe Mast Motorsports has huge split cams.

"Usually" a large split cam will either be a nitrous friendly cam, or you need it bc either your heads are just that much better than your intake. Or vice versa. You pick your cam to your parts like always said. As for an na car I would just go with a standard split like a 230/230.

Exactly.

The best cam is one that complements your specific setup. Give a call to whoever you're ordering your cam from. Tell them your setup and your goals.
