I am looking at upgrading to power brakes on my 70 nova. One thing it asks for is how much vaccum I have? How do I find this out and where is the vaccum located?

get ahold of a vac gauge abd connect it to one of the ports on the carb or intake depending upon your setup. if you dont have one you should be able to rent one from autozone

You can buy one for the price of a rental. If you have a stock cam you should not have any problems. A lopey, rumpity-rump cam looses vacuum to overlap.

I will go look for a vac gauge in the am. Hopefully I will have a vaccum port somewhere. Scotty
