Verify a 350 H.O.

Short answer: The only reliable 350 H.O. identifiers are on the engine:

1968 350 H.O. Engine Codes
Manual (WK) Automatic (YM)
Cam 067 066
Carb 7028269 7028266
Distributor 1111447 1111282

Both used casting #18 heads. Other clues aren’t conclusive — the 2-bbl 350 could have optional dual exhaust, both shared the same hood emblems/holes, and stripes could have been delete-optioned. To be certain, get PHS documentation.
