Mopar R3 Block

I don't want to do a bunch of special work either. But I don't even know what the options are yet. If it's a 9.6 block with 59 lifter bores all I have to deal with is the cam bearings I think. Don't these blocks use both std head bolt pattern and the w5 stuff?

You should be able to spot the 59/48 LBA a mile away. The one doesn’t look anything like the other.

Not sure why you are worried about cam bearings. I don’t want to go back through the thread to see. But unless the block was machined for bigger than OE cam bearings it is what it is.

All the blocks have the same 10 bolt pattern, but some of the blocks have another 10 bolt holes in them. Any 10 bolt head will bolt on any block. Any 20 bolt head will bolt on any block, you just won’t use the upper and lower rows of bolts.
