Looks like the block I gave you with the Mcode dart ?

Chrysler did this because they eliminated the bosses on the block casting under the cylinder head that were used for mounting 440's in 65 thru 68 C bodies.


Not the block that came with the M-Code I got from you, that went with another M-Code I sold a couple years ago. This block was from a 68 GSS Mr. Norms car that I still have...

The funny thing about science is that if you change one miniscule parameter you change the entire outcome to the way you want it.
