It looks like Mopar used a Hemi block casting but drilled the head bolts for a wedge head. Block was listed in 1998 Mopar Performance catalog. I have had it since 2000. Has H 2495 244 on distributor boss and 2468380-M on right side of block. Just looking for information on block. 7804460-MWBLOCK5.JPG (306 downloads)

They might be legal even with the cross bolted mains since they have a factory part number and casting number. Not sure if the Stock guys run those blocks or not. It is a lot of extra weight on the nose of the car. Those blocks are super heavy.

You must have the valve notches, if you get torn down by a tech that is sharp he will toss you without them Besides if you don't notch the block for the 1.88 exhaust valves they will hit the cylinder walls, even bored to 4.310 (+.060) over Mr.Cab Racing and winning with Mopars since 1964.
