I sit corrected. I must have confused your car with another on this board. 3600 is a bit heavy. I would suspect that at this time with possibly a limited budget, that you are in the right direction by working on shaving weight from the very front starting with the brackets. Isn't your car a 64' Polara?
Might have been my '63 330 you were recalling.
It weighs (weighed) 3,287 lbs. this spring.
I suspect the new forged crank and rollbar going in will add a few lbs. this fall..
