Block Casting numbers

[Erich]

I like your answer better. This block may be a go then.

A =3400, b = 3100 c = 3500

Then this one is going to scrap man. I was told it was a 3400.

I will go shopping for a complete 3500 perhaps.

Should be a 3100... http://60degreev6.com/forum/showpost...33&postcount=6

Big A on it.

Look for a large letter on the block somewhere (A, B, C, L). Report that back and we can probably tell you what block it is.

Is there a list out here of 3100/3400 casting numbers. I need to verify my 10224227. Considering using this block to put my 3500 top on and turbo cam in.
