Good afternoon:
Happy to be part of the club!! Here's my question.

I have a 1972 Mustang Convertible. We fully restored the car in 2009 as original. I never checked the engine as we had it restored as a driver car. As it turns out, the engine is a 1969 vintage. Engine casting number C9OE-6015 manufacture date 9C31 (March 31, 1969).
This appears to be a Torino series engine. Can someone in your club tell me if this is a 90 degree Windsor engine? If so, would that make the car worth a few thousand more, a few thousand less or neither?
Granted, it is not the cars original matching engine but is this a better engine than the 302?
Thanks for any input.

Good to see more old school joining the ranks. Sorry I can't help you out, I am only a few years into the Mustang scene, but I skinned plenty of knuckles on late 60's early 70's Chevys

Looks like that engine is a 69-70 Vintage 351Windsor. Advantages over the 302 taht came in your 72 are a good bit more power and torque, as it came before the emissions crackdown. The value would remain the same, IMO, unless you find a die-hard collector, whom would want the original driveline.

Thanks for the feedback. I bought the car as a driver so it doesn't really matter to me. But when it comes to selling I want to be sure I represent the car for what it is.

Hello and welcome,
It's always great to see another first generation car on here. Putnam huh,Whereabouts? We might be neighbors?

Ok ,onto to your tech question,I will try my best and I will give you the short version. OK 351 and how it affects your cars value? For starters what is the fifth digit of your cars vin(this tells the whole story)? Next the casting number you provided is for a 69-70 351 Windsor engine (c9oe) 2V OR 4V ,As they both carried the same casting numbers.The 6015 stands for the base part for a Ford engine so every ford engine has this number. Unfortunately you neglected to include the last digit which is more than likely a B,D,OR A. The Cleveland series of engines didn't start until 1970 at which point your engine casting number would have started with a D0AE or something similar. I wouldn't worry about the Torino,Fairlane,etc. Portion as that's not applicable/a true deteriminant All 351 Windsors had this casting number whether they were originally installed in Mustangs,Cougars,Torinos,etc. So you probably have a Mustang engine.

351 windsors are basically the big brother to the 302 ,They are very good reliable engines,as well as they have more cubes which = more horse power.

Lastly to touch upon value,Unless your car was a very rare and exspensive car having a non original engine should not affect the resale value by a few thousand dollars either way.By 1972 There were no more Bosses,Shelbies,etc. So That's not a worry. On the contrary if your car was originally a 6 cylinder auto and it now has a 351W with a 4 speed(I'm guessing) in place it will more than likely add to the cars resale value.Last thing to consider in this market Beauty is in the eye of the beholder so if the right person falls for your car who knows? I've seen people pay more Money for A shelby clone than an original shelby? So it goes to show people will pay up if they like what they see.

Ponyboy, Thanks so much for the insight. The fifth didgit of the car's vin is 3 (vin begins 82F03FXXXXXX). Does this shed any additional light on the subject? I did not see any additional markings on the casting numbers like b or c or d. If I could figure out how to post a picture or someone can explain it to me then I will put one up. Thanks

Ponyboy, also the build date on the engine is 9c31 or March 31, 1969 which I presume eliminates the Cleveland. I'll look again for a B or C or D but I don't think it's there.

Ok,
First your vin, 2= 1972, F= assy plant,(Dearborn Michigan),03 = convert wih standard int. lastly F= engine code which would be 302 v8 2bbl.

As far as your engine,It wouldn't be a cleveland because like I said they didn't start until 1970 for the first 2 digits would be DO (Which stands for 1970) whereas yours is C9 (which is 1969) . As far as pictures I wouldn't sweat it,I've seen a bunch of windsors over the years. As far as value I don't think having a 351 in your car would hurt it's value.


P.S. If you still have your original door jamb sticker,I can decode it for you if you like? Also whereabouts in Putnam are you located(Generally) Maybe I've seen your car around before?

Welcome Capt

Ya according to THIS CHART your right in assuming it's a 69 Torino/Fairlane

But if you use THIS CHART and it's a -B that would mean a 69 or 70 GT350 351 Windsor

I know what Chart I would use :p

I see and hear what you're saying but the only real difference in the castings by 69 would have been to account for "L" Changes. Contrary to popular belief Shelby didn't have his own special engines built so they all really started as the same basic block. Ford(Carroll was gone) was building the Shelbies by 69 and at that point they were really just striped,fiberglassed,spoilered, luxury Mustangs. In 69 a 351 Windsor came 2 ways in 2bbl or 4 bbl .The difference between A Mustang 351 and A "Shelby" 351 Was pretty much a pair of valve covers. Obviously you couldn't get a 2bbl Shelby,I believe the only performance enhancement done To Shelbies was some exhaust stuff .


Keep in mind we're only talking 69 GT 350's ,GT 500's are a different animal.
