I know for a fact that a stock 360 block can be built to go 9.60's and hold up to bracket type NA builds that are raced weekly at 2860 pounds. This is with stock main caps and no concrete. How much faster can they go??? I hope to find out as I believe 9.30's-9.40's is reachable. So once again how many of us need better blocks. If its priced right and machined right I would like one BUT they better push this program and get it going because some of us guys are getting OLD.
