redpony88

it definitely sounds like a good spec. should sound pretty nasty too
i've been too busy to get a vid of my 83 since i threw in my new cam, but i do scare people at the lights haha

Tell me about the engine its going in, Size, compression, heads, induction,etc plus the weight of the car, type of transmission and gear ratio. Then I'll give you my opinion of the cam.

Those numbers are useless to a degree, how aggressive is it at .200-.300-.400, thats what you need to know

Portmaster

The 228/236 @.50 and the lift of 544/568 and 110 lobe seperation tells you how agressive the cam will be. Duration tell you how long the valves will stay open and lift tells you how far they will open, the lobe seperation tells you how close the two event will happen to each other. Unless they started putting a detour on cam ramp profiles it pretty much explains itself, lol

woodsy

If you think so, those number dont even begin to tell you how aggressive the cam is.

Portmaster

If it's a Hyd roller you can bet it's pretty close with ramp angle. You seem to disagree with me. I'd sure like to hear your explination. I'm always open to furthering my education on cam dynamics

woodsy

I am not disagreeing with anyone, I was just wondering how anyone could tell how aggressive the lobes are that were used. How can you tell by looking at the above numbers that this cam uses an aggressive lobe, or is it a very lazy lobe. If you could explain that, it would be great
