New Approved 305 Stock/Superstock Block..

I have one of the little M 305 blocks. It's a really nice piece, as all the Dart stuff is. It would be great to see them make an SHP version as well; but I'm sure the cost of tooling up to do that needs to be justified. They aren't as strong as the little M, but the weight savings would be advantageous. Very glad its been approved Greg! Another option (probably more so for stock) might be the GM Performance block. Pretty much the same as a stock block, but has priority main oiling and .260" thick cylinder walls.
