no its a 88-92 cylinder, the 87 had the bigger 5 bolt intake. all years of the 250s were 6 bolt heads. i think hes geting 500 cylinder confused with it
You're right, I mixed this up with a 500 cylinder. I don't know much about the 250's. Sorry about that.
Great pictures though. Seeing your hand next to the cylinder put the size difference into perspective for me. GLWS.
