Comp cams xe268h for 318

dart
problem with Hughes is that they do not give you seat timing so really hard to tell if soft or steep ramps or what the ICIA might be
on those short comp cams
just go to the small block chevy page and see if they have exactly the same duration, lift and lca there
if so pass
with a MOPAR cam like the voodoo you have a choice of a shorter duration, earlier ICA for similar lift, or greater lift (area under the curve) at the same duration/ ICA
and that's only half the problem
a short rod motor like a chevy needs a different lobe center and ICA and ex open and intake open and exhaust close than a long rod motor like a mopar.
If you have ever seen a master for an automatic cam grinder there is a master for each lobe
to change the lobe centers takes some of the automatic out of it
You have to grind all the intakes then reset the gang master for the exhausts, and some grinders require a different master
same problem if you want a different exhaust lobe than what the catalog calls for (with and without headers for example, )
if you do see the same cam for a sbc and mopar you can do better- just use comp for a starting off point
if you have low compression look at a voodoo or Howard with the (15) footnote and think about using one size shorter cam and you will find more lift anyway
