There are a lot of POLITE members here.
In my opinion, the owner has the right to do whatever he wants.
I'm still stuck on the mindset that THIS ISN'T CUBA.
Doing stuff like this is completely UNNecessary in a country like this where the factory family parts are easy to find.
Doing stuff "to be different" leads to dudes putting slant sixes into Miatas, diesel engines in '70 Barracudas, etc.
To choose to put a Chevy engine in a Plymouth shows no allegiance to the Mopar family. None.
A Mopar guy doesn't do this. A guy that likes cars might. There is a distinct difference there.
I don't wish for any ill will to be cast upon you but I have zero interest in the success of the build.
Cheers.
