Engine it self has factory sticker on valve cover: (I write it down on the paper tonight, I'll take a picture if needed)
Engine Family = 5.8M / 6.6 "D" (2x124) Engine Displacement = 6.6L (400cid) Evaporative Family is TN - Catalisator??? D9VE-9C485-AA ACJ
Originally it had "Automotive"?? 2BBL carb, and now it's 4bbl Holley on it...
Transmission is AUTOmatic with console shift.
Few questions: Can you tell me, where to find S/N on the engine to check numbers match?
What kind of spark plugs do we need (heat range), he bought some that parts shop said it would fit but they aren't the same as the old one which we have
2 different types installed in the car...Any other usefull info we can use to make this car running is welcome. Didn't know where to ask so I posted here, sorry if OT
Thank you in advance
