Had a long talk with a good reliable source at Carlisle about Hemi blocks. He has ONE older block left and won't sell. He's heard of none coming out as of now, only smoke, what he sees is what's left of the junk batch coming to surface. Chrysler sent quite a few of that batch to his dad to see if they where fixable, not enough pots to catch the oil and water running out. All those blocks where to be destroyed but a lot got through the cracks to unsuspecting buyers. Molds are still there but Fiat wants big bucks to let them go, could care less about the racers, only money. Only thing to do is keep patching what you got for now. He's won't run the S/S for fear a hurting it, and the stocker on a limited basis.
Sounded like he was in the know, since they build cars and engines.
