340 Engine Shake

Well I found a 340 block local. Can't believe it actually.

It's a standard bore, it's a late 69 block. The main caps are missing though. Someone also painted the deck.

So I'm going to take it to the machine shop and have them look it over. See what they think.

I should be able to use my main caps, but I know there will be machine work to align hone. I'm concerned about taking too much off the deck to clean it up. I want to re use my rotating assembly and my pistons sat proud of the deck .018. I do have the Edelbrock open chamber cyl heads, so hopefully there will be enough clearance.

The best part is it was only $100 for the block. Here are some quick pics.

That is a good score and worth taking a chance on for sure.

Switching main caps you likely will need an align bore though. More to it than just a hone. Talk to your machine shop.

As far as the deck goes I wouldn't worry much about it. You can always adjust with a thicker head gasket if needed.
