Well I'm about to find out how well the stock block holds up. I'm thinking my new engine should be in the 650-670 range NA. Going to the track today for it's first passes. I'll let you know how it holds up.
GJ, is this with your stroker that you did all the oiling mods to? Looking forward to your results. Should have Dynoed no? I guess your numbers at the track will give you a pretty good edgumakated guess on HP.
