I was taken...stupid me..

The carb should work ok, a throttle lever adaptor for a mopar will bolt right on since most aftermarket carbs have GM linkage anyways.

One of my friends ran the 650 spreadbore on his 360 valiant for years and it worked fine, he was in the mid to low 12's with it, It will just need tuned to work on your motor but a carb is a carb for the most part.
