deck ...between the cylinders...between the upper "steam hole" and the head bolt hole abt a 1/4'' above it...with heads off, a bright light and sober eye (leaves me out) will see a "thin black line"...i have two 400 blocks with no crack and 4 with.

some claim the crack is not significant and claim to have run "cracked" blocks with no issues

I'm in the process of finding one right now. Cheapest one here is $400 for a 509 casting and one of the mains need replacing. $100 for a 400 is a steal, so GET IT!

Check the main webbing also, once in awhile you can find one up in there.

I might be mistaken, but I believe chevy only made 400 bb, pontiac has the 400 sb.

Chances are that was a small block. The 402 big blocks were sold and badged as a 396. Oldsmobile had a 400, also. Then again, there is always the 400M and the 400B.

My 3/4 ton 4X4 has a 400 SBC in it from the factory. I have a 400 SBC "509", bare block with high nickle casting numbers, and another 4.125" bore block as a project. Where do you think SBC, 427s, 434s, and 454s come from? Certainly not from a 4.00" bore 350 block.

RACE ON!!!

Some 70 Chevy cars had 400 badges and were 402 bb motors, a friend had a new Elcamino that way. Some were also 400 sbc motors with 400 badges.
