In search of: 400 Block

[mitz81]

Looking for a small-block Chevy 400 block.

[MattODoom]

I have a 511 casting 1970-1973 block. This casting is a 4 bolt casting number, however, some replacement blocks were two bolts. This block is a two bolt, so its rare for a 511 i guess.





I have the block and original rotating assy, balancer and flexplate.

I have a couple questions if you don't mind. What did it come out of? I looked up the casting number on google, is this it?:
3951511....400...70-73...4...Some replacement blocks had 2-bolt main caps
Is there a block suffix code? And finally, what are you looking to get for it?

Thanks

I don't know what it came out of Mostly they put them in trucks from what I understand... it was (like all 400's) a 2barrel.

That's the casting number As you can see it's one of those "replacement blocks" (im assuming a warranty service block?)

And finally, what are you looking to get for it?

Thanks

I'm not actively trying to sell it, but everything is for sale at the right price.

PM me an offer.

400 small block for sale

i have on for sale, i do not know any of the #'s off the block, but it is a 400 i am sure it came out of a 1 ton late 70's truck! got it from a buddy, it is still at his house, i can pick it up if any one is interested!
please call 616-644-0616, i do not check board much so please call if remotely interested. my block i s a 4 bolt main block, i guess the 2 bolt blocks are better, as every one wants them to splay the main caps!
splayed caps are stronger but i have never broke a crank.
mine would need some machine work, bored etc.
thanks,
Brad

Im can get the GM 400CI BLOCKS

I can get you a 400ci block, a two bolt or a four bolt.. I would recument the two bolt, Its stronger than the 4 bolt that they put out, But let me now price from $275.00 and higher just let me now witch one you want, These are getting to be a little expensive..
