The siamese block is the newer block. They both work fine. But the siamese is better since it is more ridged.

The old Hemi blocks held up just fine for decades. If it ain't broke, don't spend 3K fixin it.

If a new block has to be purchased,get the best iron block available.It could last your lifetime.

Those are 12 point rod bolts, not studs. The divot in the head is to produce a measuring point for the streach guage.

The main bolts that came with the block are stout!In that picture you see a Bryant billett 4.5 stroke gun drilled and knife edged,all the little crank tricks were done.I received this crank in a car sale,he paid cash and some hemi parts.Was a used fuel crank and had to install a converter register on the back.It also wears Manley "H" beams with ARB bolts.Diamond pistons swinging on that one

For a mild street build, let your pocketbook be the pro.

Yup, like Rusty says...
Mine was made in: 05 69 (May 1969)

 

[mattsinger]

buy what you want...but for a mild build, the stock block will be fine

The best iron block available is the World block with updated oiling.
