The number you had question on, L.H. rear of block just below head. That is where they stamp a partial VIN# and should match your VIN if it is the original engine. Your car looks to be a 73 and I think the number you posted might be 72? So your car had a DSO code of 90?


When a man is in the woods and talks and no women are there is he still wrong??

Hello 6DUB606, Welcome to the best site you could have possibly found for 71-73 info, answers to any and all questions, and comradely.
[ The engine is a 351 C transplant but runs fine.  Number on back of the block behind left side head reads 2A2030308.  Any ideas where this may have come from] ?
The number on the rear of the head normally consists of the model year, assembly plant and the last six digits of the serial number of the vehicle it was production installed in . In the case of your donor engine, the "2" indicates the model year 1972. "A" would indicate Atlanta which in 1972 was building Gran Torino's. The 72 Torino was a huge sales success and was built in great numbers at several plants, so the chance of having a Torino sourced engine is pretty good since they were built in far greater numbers than the Mustang.

No Officer...I really don't know how fast I was going, my speedometer stopped at 140!

Yes - it's a '73 ( VIN 3F05H155490 ) DSO on Marti report is 92 = Export via Newark N J.  After that ? who knows.  Had a California plate from 2016 when I got it.  I see a follow up response to the engine question also.  Appreciate all this good info.

Yup - that fits.  I colleague suggested maybe from Mercury Marauder or Cyclone so we're in the ballpark.  I like the Torino option too.
Thanks for this reply.

6DUB606, with the exception of the 03-04 Mercury Marauder which used the DOHC 4.6 from the 03-04 Mach 1's, the Marauders used FE or 385 series (429) power. There were three levels of the Cyclone in 1970-71 and only the Cyclone GT came with the H 351 standard. The 1972 Montego GT replaced the 70-71 Cyclone series and was equipped with a 302 as the base engine. There was a early but short lived Cyclone trim option on the 72 Montego (approximately only 30 were built)  but was restricted to the Q 351 and N 429. The "2" and "A" on your  engine pretty much locks it into a 1972 Atlanta Gran Torino or Montego. Sorry, wish it was a high performance engine like you would find in a Marauder or Cyclone!  But in your case the H means it is still a Cleveland engine and all of 'em can be made to run!!
