The engine had not been apart till I got it. I knew both of the former owners and the history of the engine. It's on an engine stand with the heads off and it has flat top std bore pistons. The heads were not mw. Maybe something Chrysler did on the assy line? ----- Original Message ----- From: "Dave64" <lt7dave@xxxxxxxxx>

I think the valve reliefs are the only difference between the mw and sw blocks. Of course, the assembled mw engines had higher compression pistons, etc... But the blocks are probably the same other than the reliefs. Could be possible that someone put them in there after the fact?

I think 426 MW has the reliefs too, from what I've read - just trying to verify, though. I would think folks who sell the new repro heads would know the answer. I'm a long way away from any of this, but I find 1/2 the fun of our cars is thinking and dreaming about the path out in front.
