I am hunting for a WS engine to replace the mid 70s engine in my 68 GTO HO. My car has a build date of Nov 17 1967 so I need a fairly early date code to make it closer to correct.

---Since the car will never be a matching #s car should I even worry about the date code?

I need a complete motor setup. Help me out to inform my hunt.

Here is what I think I am looking for:
Block: block code:WS, cast number: 9790071
Intake:???
Heads: 16
Carb:???
What else do I need that is date coded or otherwise numbered? (pullies, etc.)

--I currently have a 1975 400 motor in the car. What if anything can I pull of this engine that would still be correct on a 1968 WS?

Here are two options that I have found so far. What do you think??

Option 1: $1800
-Unassembled motor (Intake to Oil pan)
-WS code block casting number 9790071 Date code K247 (October 24th 1967), Stock Bore (pulled heads and measured bore at 4.12")
-Heads stamped 16 at exhaust port, Date codes K287 (October 28th 1967) and K307 (October 30th 1967).
-Engine turns free,was last run aprox two years ago, stored inside.
-Included are the block, heads, engine intake, valve covers, starter, points distributor, bellhousing, and some other parts.

Option 2: $1500
-Block, Heads, and Exhaust Manifolds
-Block: WS, 9790071, date code J137, Standard bore but one cylinder is deeply pitted and probably needs a sleeve
-Heads = #16, date coded J027 & J047


Thanks for the input.
