It’s me again Ky Joe
I just found out that I got a crack in my block it’s right at the GM plate right In the middle of the block. Not really sure what my options and could I possibly find a different block and put my head on it?

Bummer!

I suggest that you pull the head off and make sure it is usable (not cracked too). The pre-1928 four cylinder engines are notorious for cracking near the single exhaust port because of all of that heat being concentrated in one spot.

The '28 engines distributed the heat better by having two exhaust ports. There are other improvements in the '28 engines too, such as push rod covers and more horsepower.

When a single exhaust type Chevy engine died, some folks replaced them with a '28 engine. It is mostly a bolt in affair, but there are a few items that need to be modified, such as where the exhaust pipe meets the exhaust manifold.

You do not mention a year of the engine you are working on. The early engines are prime candidates for threaded crack "stitching" since they have non pressurized cooling systems. You should be able to find examples of that procedure in the technical references on the VCCA home page.

FYI, if you're jumping into an engine rebuild, you might want to grab a few cups and read my rebuild adventure. Here's a link to the beginning of it: Resurrecting a '28 4 Banger
