WTB 400 Block & 383 Crank

[WhompinWedge]

Looking for a GOOD 400, bare, unmachined block.

Steel 383 standard crankshaft.

The closer to Ohio the better!

Thank you,

I have a couple of standard bore 400 blocks with main caps. Cleaned and magnafluxed. I would probably part with one of them. Not the closest to Ohio though.

I have 400 blocks and 383 cranks in Louisiana. Have a 230 casting and a 530 casting 400 blocks

The bore on the 400 is too large for a 383 Stock Eliminator
engine unless you sleeve all 8 holes.

The 383 blocks generally sonic thicker.

I have all that stuff as well But I am also not at all close

I also have 383 blocks in Louisiana and again, we are not close to each other

So would you prefer a sleeved down 400? Or does it become failure prone?

Absolutely No.

The issue is many good machine shops can install a single sleeve or maybe
two, without geometry issues.

However, I have seldom had any success if every getting a machine shop to replace
the all with issues. We need extremely precise machine work for the class we race,
as ring seal is very critical for us.

It is a fortune to sleeve all eight, try $2,500 to $3500.

You could find 230 cold weather 400 block for a quarter of that.

Beware VERT FEW 230 Blocks are Cold Weather Blocks = The vast majority
are NOT.

We run the absolute fastest and quickest 400 stocker in the country so we
have done a lot of time and research on the 400 combo.

I have been talking to the Poster and he is building a NHRA stocker.
