what solid cam is equivalent to a hyd 268 ?

The Isky E4 in a 273 works very well. I've tried a few cams in 273s over the years and the E4 is the best I found for use in low and high compression 273s. It's similar to the factory hi-po cam. Gotta agree with toolmamikes recommendation.
what are the specs on the isky e-4 cam ?
