Looking for any leads for my cousin. His block was destroyed by the machine shop yesterday. Shop is willing to replace but finding a good one is not easy. He is looking on Long Island first but out of the area may have to happen. My cousin was supposed to pick up his engine tomorrow but I guess things happen. So if any of the car guys on here know of any leads I would greatly appreciate it. Thanks!
let me look, if I don't still have one I know a guy who does

I've got one. Out of a 1970 Blazer. [I've had it since 1980 .... 36 years!!! HOLY [email protected]!!!]
4 bolt main, [only made in '70-'71] std/std crank [short block still assembled].
I also have a set of .030 over forged flat top pistons, NIB, that go with it.
I was building a 406 at one point too.
$750 for the lot.
Which machine shop did he use???

I don't know which shop. Rather not put it out there. Don't want anyone thinking he is bad mouthing them over an accident.

400's you can only bore so far...before the walls get thin.

They were notorious for overheating. Siamese water jacket I believe, so yes, careful with boring them.

They do have the siamesed water jackets same as the current 502's.
While any block should be sonic checked for core shift before boring I knew a guy running as .060 over 413 that was a complete animal!
Overheating was a problem but more due to the head gasket design than the block .... they made the "steam holes" too small. Later corrected by Fel-Pro & others.
As usual, older is better than newer. 1970 especially used a higher nickel content in the cast iron. Later they went lighter & cheaper.
That's enough useless trivia for today
