Hi there. 351C engines built in 1969 were "M" codes. They were 300 bhp with an 11:0: 1 compression. There are no 351C cobra jet engines available in 1970 for Mustangs, that I could find in Ford Stats or other places. Hope this helps and check that Vin#. Cheers from Dearborn, Mi.

Thanks for sharing your time and cars set up . The history lesson is a priceless picture into Detroit and OHIO history.

Wow

when Jonnys right ?Hes right !!!

Thanks for the upload, I have a 69 Mach 1, it's a great car sure.....

Well that's a boss 9 scoop not a shaker and yes all 70s had rear maker lights. It was state law in 68 for all cars to have front and rear. And every 70 I've seen has them including mine. Unless its custom quarters or shaved. And the deluxe Interior was available in many other models. But you were right about most the other stuff

It is a simple matter to identify those cars... by the VINs. 1969 (the 5th digit/letter identifies the Engine that came with the car): F=Engine Code((F-302cu V8 2B, G-302cu V8 4B Boss, H-351cu V8 2B, L-250cu V6, M-351cu V8 4B, Q-428cu V8 4B Cobra Jet Big Block, R-428cu V8 4B Cobra Jet Big Block Ram Air, T-200cu V6, Z-429cu V8 4B Boss) 1970 (same 5th digit/letter): F=Engine Code((F-302cu V8 2B, G-302cu V8 2B Boss, H-351cu V8 2B, L-250cu V6, M-351cu V8 2B, Q-428cu V8 2B Cobra Jet Big Block, R-428cu V8 2B Cobra Jet Big Block Ram Air, T-200cu V6, Z-429cu V8 2B Boss) Relying on parts to identify a car is never reliable, since anyone can change a part. What I noticed was the paint ("grabber" blue) that is on the passenger fender (with the "Boss" decal), also on the panel below the rear window, on the passenger side roof rear panel, the rocker panel below the door, and on the hood and headlight mouldings. This would indicate that, unless someone went to a lot of cost and trouble, that the '70 is most likely a Boss 302 Mustang. As for the Export Brace, the same brace was used from 1965 until 1970 and they all were one piece (ford part number C5ZZ-16A052-E ). These cars are worth restoring back to original, but to do so you need to know for sure what you have. From just your video, I would believe that you probably have a 1970 Boss 302 Mustang in Grabber Blue. But, as I began this reply, it is a simple matter to check and know for certain (without speculating or relying on installed parts) what the car is and what factory equipment was installed.

A lot of your information on these two cars is just flat wrong. Not all 1969 fastbacks had the simulated quarter scoop. 1969 Boss 302 Mustangs did not get the quarter scoop. The 1970 Mustang is quite possibly a small block car from the factory as it doesn't appear to have the shocktower reinforcement plates that the big block cars and Boss 302's got and it has the small factory radiator. You could get a shaker scoop on any Mustang with a 351 or larger engine in 1970. The exception being the Boss 429.

Thank You! Are you selling the 69?

"Fiberglass quarter panels.." 😆

I hope all can learn something from me

Guys please read what the title of my video say the difference between a 69 Mach1 and a 70 CJ fastback mustang

1970 is a boss car send me the vin and data code my friend and ill look it all up the 1970 will have a boss 302 engine code or 351c engine code
