440 engine casting numbers???

[andy74]

i decoded the longer numbers,2536430,which means 67-72 440 engine,but the new engine has a dash 9,(-9)after that,what does it mean?

9th time the mould was used to make the sand cast for the block

[andy74]

no big deal then right?

no big deal at all.  the moulds can only be used so many times before they become brittle an cause for bad castings.  yours is the ninth mould made and used.

thanks guys, i really wasnt sure. i read the article on 440 sources site,and figure this must be a 68 block,no cast in ribs,and the date is 3/22/67. the crank was turned 10 under,and block was line bored,bored .030 over,has the pistons installed,arp rod bolts,,everything looks great.i know we have all discused the speed pro l2266f30s,but thats what i have in it,but after speaking to ron,and the heads i have were milled down,i should have 9.3 to 1 comp,.pretty good score for trading some extra 3rd gen stuff i didnt need any way!

Actually, the "mold" is sand and only used once.

The dash number after the casting number is the number of core plugs that were replaced in the casting core used to make the sand mold.
