It is widely know that Crane Cams grinds the summit cams until Crane went out of biz. What is left on the shelfs is all that is left until summit gets a new grinder.
More than a couple cam manufacturers use the same lobe profile as for a chevy, which doesn't take advantage of the mopars' larger lifters.
Actually, ALL cam manufactures use Chevy lobes on there cams for all makes since it is easiest to use. BAR NONE!
Taking advantage of the MoPar lifter yeilds little gain on mild and med. street builds on only taxes the vale springs. This advantage is a minor gain at best in this area.
If you step up to the plate on a decent street build, it'll show an aveagre 15 HP. The stronger/more radical build, the more power it will show.
4 barrel carb and intake and headers are good mods. I wouldn't get too crazy though without a rebuild, the 4 barrel and headers can be re-used if you rebuild later.
