isn't the 268 cam a split duration? at least the xe one is.(268/276). i agree to change the manifold. that cast iron is hurtin' the performance.

Comp Cams has a standard single pattern cam line up and the 268 is something like a 218 @ .050 in duration.
The XE268 steps up to something like 224 @ .050 duration.

Stall, tire size and car weight are key combos and inforamation when looking at cams and there durations to match up.
