I must admit that I've heard a very similar story, which, at this point, I have to consider an urban legend. A local guy in my hometown had a boneyard of old Mustangs when I was around 15 and getting into the hobby, and I bought several parts from him. This was 17 years ago. The word on the street (not only from him but from several other sources) was that he had built an absolute haint of a 289/302 hybrid in the late 70's/early 80's. At the time, I bought the story hook, line, and sinker being 15 years old.
Time brings some fuzziness as to his claimed part list, but here goes (I'm not even sure if these parts would work together without introducing pistons to valves):
289 block
302 crank (which should only make it slightly bigger than 302 cubic inches, right, and would cause valve clearance problems if I'm not mistaken)
289 hi-po rods ??? (see above)
289 hi-po heads w/ port work
a 3/4 cam (what in Hades is a 3/4 cam?)
other bastardized parts I simply can't recall at the moment
The legend as I heard it was as follows:
He welded the spider gears in the differential and lost the car shifting from third to fourth gear at 120 MPH, which caused him to wrap the car around a tree in a field. He told this graphic story of how he came to, thrown from the car, and tried to stand up, in the process realizing, when he fell down, that his tibia (leg bone)? (I'm no doctor, I only play one on T.V.) was buried into the ground and prevented him from walking.
The strange part about a good urban legend is that there is always support for these types of tales. My brother's ex wife's sister's ex-husband, current husbands at that time (wow that's confusing; yes the trailer porch fell and killed 7 dogs), claimed he had driven the car back in the day. He claimed that he gassed it at a stop sign at an intersection and lofted the front wheels across the street into the ditch accidentally. I'm callind bullshart on that one, but these sorts of stories apparently exist out there in Mustangland.
I'm not trying to be a d*** to the guy that posted this, but he should realize after all these posts that something is preposterous here.
P.S. I really apologize for the long post, but I am being held hostage by a guy who caught me drunk, let me pass out, and removed my kidney in an iced down bathtub. He is holding me hostage and made me write this post by threatening to flush my kidney down the commode if I make any sudden moves and don't post a long reply
