So I'm browsing through the West Coast craigslist ads and I see this:
"A brand new L-6 series racing head for 240/260 series motors. This is a factory competition cast head with smaller combustion chamber & larger ports. Last of these heads to be imported into US by Nissan Competition (NISMO) Purchased out of stock in 1996. Not available anywhere. Never mounted, bare head, in box. Those Datsun collectors will know what this part is worth. Paid $1,200 for head, as I was a Nissan racer out of the Electramotive shop."
Unfortunately he didn't post any pics or any info regarding the casting number. I don't remember ever seeing a Nissan factory comp. head for the L6 listed in the old Datsun Comp. catalogs. Wasn't the LY head the only factory race cylinder head made by Nissan for the L6?
On a another note, post # 1 for me.
