1970 SS 454 Monte

Post by Monte Carlo 454 » Tue Sep 13, 2016 11:52 pm

Hi guys - New member here:) So, I bought a 70 454 over 90% restored car in the spring, 454 mild cam, edlebrock intake, coated headers, new R4 700 tranny, pneumatic shocks, new front end, new springs, disc brakes, new ac, battery, kill switch, electronic ignition, low drag alt power master.

I want to upgrade to posi traction. The rear end is 10 bolt now. Should I go 12 bolt? And as far as gearing what would be a good compromise ratio? I need to do some highway driving 65-7ph for 30-50 miles on occasion 2-3 times a month, but I want a little more take off omph than I have now.


411 and 473 concern me. Your thoughts?
