Cam choice questions, sorry long post

your cam choice should match the head flow and intake you are using.

Best line! My fav to say by the way.


I like to use as much lift as possible without getting into the area where the head flow stalls for my aggressive street, street/strip engines. Milder engines can just have something under .500 with the duration to match the driving RPM /cruise range. If I'm looking to do a sub 11 sec run, perhaps more lift than the head handles, but barley.

Knowing what the head flows is a excellent thing to know when looking for a cam and chasing a E.T.

I think that Duster could use some fiberglass to lighten it up. (3200 or less. Bumpers and hood are a great place to start as well as seats. While 3400 is a little hefty, it should still run well. I do not see a power problem with 11's. Gear ratio wise, yes. 4.30's min. gear. I'd like to use a set of 4.56's for this. (10 sec run)

Both cams are nice. I think I myself would like the roller for the slightly lower RPM band starting point and broad RPM range. Since cost is an issue, I guess the choice is made for you.

My cam choice for a 10 sec run would be something like a duration of 260 intake and a little more exhaust with a tad more lift than the head flows on both sides.

For an 11 sec run, the suggested Hughes Hyd. would do it.
