D Dart spec. Anyone build one?

I'll probably go with the E4 kit (which just jumped another 100 bucks in price this week). I was just wondering if there was anything out there that would get close to D Dart spec but with the low compression pistons.

Performance wise, I think I'll actually be better served if I can get my hands on 3.55 or 3.91 years for my 7 1/4 SG than trying to put a giant cam in.
The D Dart 273 ran 10.5-1 compression, the big cam, stock intake with a bigger Holley, and headers. They also used 4.86 rear gear along with the 4 speed. They ran 14.30's @ 92.
