I am changing my answer. I thought he was looking at switching from one to the other. But after looking at these threads and seeing that he is building an entirely NEW motor, new heads, new block and I assume new rods and pistons........I am falling back to my other answer. Why would you NOT build a B-1. The bare castings MIGHT cost you a bit more, depending on connections, but otherwise parts cost is a wash.
Rockers, headers and other stuff might be the issue Monte.
Unfortunately this ...like all of my builds will be on a budget. I think in my case sticking with the SR's might be the best bet.
