the +2 or +3 is already ground into the cam, so there is no need to "advance" the cam. just put it dot to dot and have fun

 

With the truck intake 8 degrees of split is enough. I'd recomend something like the Comp Cams 281LR HR13 (54-459-11). The spec's on it are 231/239 .617/.624 on a 113. The off the shelf grind is with a +4 advance with along with the 113LSA will help to keep the part throttle low rpm drivability reasonable. It would be easy to go bigger with that much stall, but I wouldn't recomend bigger since you want to keep the drivability in check.

 

So you guys think a 239/247 623/623 114+2 would be to much of a cam in a L92 headed 408?? I have heard both ways on the cam and am now wondering. Any of you have a link to some info to show either way?
