327 Block Differences?
What is the difference between the 1965 327 block ID 3782870 and the 1965 327 block ID 3858180. Both are small journals.
Can I use either one and rebuild a 327/350?

The 180 block had thinner cylinder walls than the 870. The factory used the 180 block for engines 250-375 hp.

That is what I figured, thanks much!
They are offering the block and internal parts with double hump heads for $300. Other than visiable cracks and severe gouges in the cylinder walls, what else should I look for?

Are the main caps on the block?
The price is cheap enough.

Probably a different block. Scrap iron gets about 200 bucks a ton these days.
Where are the cracks and how deep are the gouges?
Looks like you'll get a pair of double humps for about 280 bucks, which is a fair price.

I hope you meant you were going to look for cracks and gouges, not that you had already seen some in the block?

Correct, I have now looked at it and no visible signs of cracks in the block and no gouging visible. everything looks fairly clean. So, I have the block, crank, pistons, heads and some extra parts all for $300, now it is time to rebuild it for a fresh motor. Thanks for all of your help.

Basically it was the same crank as the large journal 307 cranshft and interchangeable with it.

That is good information. Thanks, I have a cast 327 crank, I was bummed when I pulled it out of a core engine and found the cast and not forged crank, set it aside and never measured. Now I know it should be a large journal. Time to go back and see if that block will make a 383!!! Maybe it is actually one of the rare 350's with the block vent? That would be pretty cool.
