Any interestin these? I have two and would need to sell together. Bought them as NOS new old stock this past summer for project but changing builds. These are new never used with caps and brass freeze plugs installed. Can post pics but these are just new blocks. Heading down next week to drop off engines to be shipped so if you need any additional info I can get it then. These are wrapped and palleted and ready to ship from more power racing near Grand Rapids. I'm not going to play the game list high-except lower so bottom line on them is 3k for both and that's 500.00 below what I paid and they are ready for imeadiate shipment. Plus shipping from Grand Rapids. I will see if I can post some pics tomorrow with current bore size from GM.

Casting numbers 10051107

What I found.

10051107...454...............4-bolt, Bowtie, MkIV, 9.8" deck, siamesed cylinder barrels, 4.25" semi-finished bores, can be bored to 4.50"

I could use some 502 gen 6 blocks. ��

What's the bore size right now? Are they the the 4.47" blocks that were for sale earlier? I need these like I need a hole in my head...
