Look at the engine code stamped next to the dipstick hole on the engine deck....350hp should stamped TS for Stage1

If you plan to rebuild it the HP rating has no relevance.

Also if it came out of a bi g car it would be the lower HP Rating. Your pictures show red rocker covers so it is not 350 HP which would have chrome.
