Welcome to the site!
I'd upgrade the brakes, and make sure the fuel tank is clean!

I agree with Rod front disc brakes.

x1000 on the disc brakes. It's the best money i've spent so far.

You know there is a saying on one of the car forums I used to frequent
"No pics, Never happened"
Would love to see pics as you progress

64-66 is a single master. Good to change if only for safety.
Duals are 67-70. When swapping to discs, you must match cylinder size and force. This often requires a booster (tough to find room!) or changing the M/C.

dodge man i installed front disc. the new mc i used was out of a 73 dodge van it had front disc and rear drums and no booster so the front were disc but not power brakes. and you will need to do some cutting to get it in. or maybe look at a valent see what they had.. the disc use more fluid so i'd suggest changing the mc.

thanks DIX, i thought i would have to change it my m/c on there now has small resavores, i know with disc you need more fluid to pass back and forth with the pistons moving that requires a bigger m/c i just didnt know what m/c would fit, do they give you all the info when you buy the kit

Yes they do, i think i had $363 total in my swap with drilled and slotted rotors. It stops great, it's saved my butt more than once.

Drum=similar size M/C bore as wheel cylinder bore (usually between 3/4" and 1"). This means similar pressure at M/C and at wheel cylinder rod.
Fluid displacement must take up against heavy springs and move shoes out about 1/8" or so. Regular adjustment or self-adjusters keep this to a safe minimum so you don't run out of pedal before the shoes engage.


Disc= small M/C Bore (Again usually between 3/4" and 1") to a caliper with a much great diameter bore (often around 2-3"). This means a larger fluid displacement which if not taken into account and planned for could be on the order of 2 or 3 to one. That would require 2-3 times the pedal throw, all other things being equal. This is accomplished by holding a tighter tolerance on pad drawback and often larger M/C bores, which lowers the fluid pressure.

There is a whole lot more to it, with different pedal ratios, PSI and how it relates to a round bore, and other things. Discs require more pressure too, which is why almost all are power-assisted.

There are many books on it, and a lot of very high-level websites on braking. I suggest that you research it if you plan on swapping.
Here are a couple I just found with searches...

Basic design
http://www.how-to-build-hotrods.com/brake-system.html

http://www.popularhotrodding.com/tech/0601phr_braking_systems/viewall.html

some simple math
http://www.brakeandfrontend.com/issue/article.aspx?contentid=79680

and if you want to go crazy, here is a good book that is crazy high in price!
