Interesting history on my 1967 Hemi GTX

[skyman51]

I learned an interestring thing about my 1967 Hemi GTX. Larry Shepard the well known Hemi expert rebuilt the motor in my car in 2007. I recently was emailing him and he told me that when he tore the engine down he found the long block was a Super Stock. It had high compression pistons, radical cam, fly wheel and Super Stock crankshaft. All this with a street Hemi induction and exhaust system. The block is stamped on the pad HC 426 and a maltese cross, which is high compression and a smaller diameter craankshaft. Larry said this happened once in a while, that they had a car come down the assembly line that called for a street Hemi and there was not an engine ready so they put in what ever they had, but would not stop the assembly line to look for a motor. How cool is that? He is going to write me a letter documenting that and that the motor in my cars is original, never having been apart.

Very interesting. Thanks for sharing.

How did he rebuild the motor? Street Hemi or Super Stock? I would think it should be fairly easy to tell by the exhaust note if it was high comp w/ radical cam.....

It was rebuilt bone stock. Street Hemi.

If your car was built with S/S parts in the engine, and the block ID pad is stamped as such, wouldn't your car be de-valued if the engine was rebuilt w/o those parts?

Not in my opinion. The two original broadcast sheets and the Chrysler Historical paperwork show a 1967 GTX with a Street Hemi engine, not a Super Stock Car. The crank and flywheel are the original, but the 13.5 - 1 pistons and the cam were replaced with stock. If it had been rebuilt to Super Stock specs today it could not be driven without $10.00 race fuel on a car that only gets 7-9 miles a gallon now. I run it on pump gas and mix in 3-5 gallons of 110 leaded CamII. I mix it really to mitigate the ethanol in the pump gas which over time ruins rubber in the fuel system. The compression is now stock at 10.25-1 which would run fine on the 93 octane pump gas alone.

So basically it's worth nothing more than a regular street hemi, since you've had the engine rebuilt.

Thanks MarPar, apparently the above comment does not think a real Hemi is worth very much. My motor is original from the air cleanser to the pan, including carbs, wiper motor, watwer pump, radiator, fan, intake, exhaust manifolds, alternator and starter. If you can find one like that and it is restored from 1967 (Elephant Motor) you can expect to pay as much as 25K for it.

skyman51 dont beleive that story. All Racing motors where installed out side the plant. this never happened.

I don't mean to be rude, but before you make a statement you should know what you are talking about. Limited numbers of Plymouth and Dodge Super Stock cars were buillt at the Lynch Road Plant. As amatter of fact they were available in many colors. My Hemi GTX was built at Lynch Road. Larry Shepard's father worked with the Godfather of the 426 Hemi, Tom Hoover at Chrysler. Larry , his son, told me that what I describe and what he documented, happened often.
