Got the call from Matt Hensley today. My 400 Block didn't sonic good. Imagine that. I got one more block to try. If it don't check out good. I think I may go Gen 3. I'm not gonna go fishing for 400 blocks in hope of finding a good one. So I may have a Molnar 4.25 crank and rods with Diamond -24cc pistons ProGram 2 bolt caps a Dwayne porter specd small solid lifter cam with HYlift Johnson lightweight edm lifters for sale. Which with a set of 240 TF would make a awesome 512 street engine. Will see in a week or so. Man Im bummed about the block situation.
