 Hi all,

Well got my 451 block back from machinist and started to check it out.
It doesn't look right to me...there is a lip that your finger nail can catch
Has anyone had this happen before?
Whats the thoughts here, will it matter or should I return to the machinist.
Thanks in advance

 Did they use the correct caps on the correct mains during line honing?
I presume you got the correct one on the proper mainsaddle right?

 The caps were not off this block, yes they are installed 1-5 front to back....all the hone lines line up....it looks like all the caps were in the correct location.
I'm going to take it back next week as I'm not comfortable assembling it as is...

 Doesn't look like the block has been tanked, a lot of crud in the pictures.

 Looks like it been done with a cylinder hone - the cross hatching

There's no way that could be considered line bored - have you checked the dimensions?

+1 on the hot tank - you don't want any rust near/in the bolt holes and bearing surfaces
