Rickster,
I really don't see why if you are going to use it for street use the regular 428 built right wouldn't be as good as the CJ or SCJ versions. I know the cylinder walls on my 69 SJC are thinner as it is bored .065 over and was just sonic tested about a month ago and everything is still great. It came in the 69 limited edition Torino Cobra that I ordered back then. But the 428s that Shelby used in the 60s weren't the CJ engines except in the GT-500KRs.
You are right on about the prices. Everything in my engine costs about what my house did when I built it.
