painted under the hood today, went to get new spark plugs for my 66,

originally i was told this was a 250, but 230 is stamped on the block, did they just use the same block and no different stamp?

next i had to run to the store several times to get the right plug, didnt have a good one to show them, i finally found the right one myself and it says it belongs to a 250 from a 1970-75 c10

i thought the engine was number matching, but i guess he mightve switched the head?

is there a benefit to this? im so lost with this engine, i wish PO would tell you everything theyve done to the truck, can anyone help?
