Re: Best CAM for a blower motor? I was wondering the same thing. There is a lot of info on N/A cam selection, but not much that I can find for blower use. I am guessing that a split duration 218/224 .527/.534 on a 114 lobe sep. would be good for me in a daily driver 6-speed with stock heads. But, I really am not sure - I have no experience with forced induction. I would like to find out before I get the blower, that way it will all work together.

About 10 more degrees on the exhaust side?
Like a .224/.234 ?

yes thats exactly right, 224/234 .570 .580 would be a cool setup for a traditional SBC
I think on a ls1 you can get away with as littleas 6 degrees, due to the exceptional exhaust flow with LT headers. So 224/230 with 580-590 lift is a cam i would love to see used. its a cam id like to use myself.

Re: Best CAM for a blower motor? Yes.
However, a split duration cam (little extra exh. duration) will work significantly better with forced induction (IE - N2O, Blower, Turbo) <img src="images/icons/tongue.gif" border="0"> <img src="graemlins/fluffy.gif" border="0" alt="[Fluffy]" />

Holes, that cam is a little more than you need for a stock shortblock. Anything over 224 duration and you're just wasting driveability.
A good blower cam for example is the Hotcam........ While it does excede the 224 limit on the exhaust side, the intake side somewhat levels it out so it's not to much overlap for a stock bottom end. A guy down in FL I know picked up 42 rwhp installing a Hotcam in his single turbo car.

Been looking at SC Cam overlap a bit this week.
Think the largest I'd consider is a 222/228 114 for an SC.
218/224 114 to 222/228 114 seems to be the sweet spot for 34x CID blower cams. May start to overlap slightly above 220/226 114.
Lift anywhere from .558-575 is nice.
Was researching with CompCams.
