Not long ago a friend was cleaning up and he knows I'm a sucker for helping him create more shelf space at his place. Now I wonder why I do these things, I don't need this stuff and Ill never use it....
1 - 350 4 bolt main block, late design with one piece rear seal, casting number 14088548 mid 80's pickup truck
1 - 350 2 bolt main block, appears to be 1972? .030" oversize, surface rust in bores 3970010 code CKB
2 - 350 heads (orange) 3988920
1 - 350 iron intake 3973469 Q-jet looks to be 1971 350
$100 for everything? $30 of that would go to Canadian Poncho.
If it was on the East Coast of Australia I'd buy it too! The 350 block is right on the cusp of being cast for late 1972 production or ready for 1973 production. As Rebelrouser says, 1972 its an L65 TH400, 1973 it's for a manual L48. The 15th June assembly date does suggest a 1972 L65 though. The 920 heads are F2 as well so almost certainly original to it.
