Went to pick and pull today.. an hour or two of wrenching yesterday got me a 32 spline 203 and the adapter. Today i went to another yard and pulled a 454 out of a late 80's dually work truck. Gas and coolant were still in the lines so this big block should be a runner. 90 degree weather i was sweating like crazy, got a sunburn too. Scored the 32 spline 203 (for a doubler) and the COMPLETE 454 for under $300 out the door.... and i can still get core charges back.. guys were asking me if i worked there.. and how much if i pulled an engine for them... lol. Can anyone get me any information on these head castings? 14081045 All i'm finding is " 78-87...oval...OPEN...454 ".
