I have a 1965 nova wagon that i drag race i run drum-drum brakes for zero drag. I would like to change over to a dual master cylinder (manual no power) 350 15to1, 314dur. 274dur .50, .680lift makes no vacume :D . So i would like to know what year, car, brakes, ect.. to tell the napa guy to order for my car. Thank You

Welcome to the site Perry. Sounds like a nice wagon, post some photos when you can.

A master cyl for a 67 - 72 Nova with drum brakes and no booster should work just fine. Before installing check that the depth in the piston for the pedal push rod is the same. If not the push rod will need to be changed.

you'll also need a proportioning valve...either stock or like something from Wilwood >http://rds.yahoo.com/_ylt=A0geu7AOr0dGqBkBQKFXNyoA;_ylu=X3oDMTE5YjNkbDV wBGNvbG8DZQRsA1dTMQRwb3MDMQRzZWMDc3IEdnRpZANNQVAwM DRfMTAy/SIG=12of3gt03/EXP=1179189390/**http%3a//www.wilwood.com/Products/006-MasterCylinders/001-PV/index.asp

Jay is correct. The stock valve isolates front and rear with a shuttle valve to ground the circuit for the warning light. It has no proportioning feature. One from any drum/drum GM car will work for your application.

Thank You guys. I will go get a stock drum-drum dual master cylinder for a 67-72 nova then. I tried to upload a picture but it said i exceeded something or other :sad: .

The photo may be to big. Try sizing it smaller and save as a JPEG. You can also email it to me and I'll size it and send it back.

Sent you two pictures of the motor and car. Thank you for resizing for me.

Perry got them and working on it.
