Casting and date code identification help
Just want to start off by saying I'm new here and to forums, thanks for letting me join. I see there's a knowledgable group of people here and can hopefully help me out.
I just bought a 454 and was looking for some help with the casting number and date codes to see if this is worth what I paid for it
It's stamped Hi per pas 3999289
Also has
TO501DWB
13K554948
It's not torn down yet (actually haven't even picked it up yep) so I don't know if it's a 2 or 4 bolt main. But it looks like it has an original aluminum intake on it
Any help? Thanks, Roy
