The bore size on that M/C is only 0.83 in... I think that may be under sized for the OP's needs...

You are likely correct...I just posted the link for philbilly.

Can't remember how it goes, is it the larger the M/C bore the harder the pedal effort or is it the other way around the smaller the bore the harder the pedal effort?

I think it is the latter. We use a 1.032 bore with 4-pistons in the rear and 2-pistons up front.

smaller bore=easier but more stroke
big bore= hard, quick pedal
too big= "holy ****! I can't stop!!!!"

This is a bolt-in replacement for the heavier GM cast Iron master cylinder.

Q. I'm building our '69 Chevelle wagon into a stocker. I'm leaving the rear drums, but am converting the factory front disc over to aftermarket. I've removed the vacuum booster and master cylinder assembly, as well as the factory proportioning valve. I intend to install a aftermarket adjustable proportioning valve. At this point, I plan to adapt a Mopar style master.
Does anyone have any idea if a "plug and play" master cylinder set up is offered? Strange does not make one.

A. This one is a bolt in for what you are doing NAPA part number M2456

On the 13-1945 master cylinder you guys speak of which port
is front brakes the port closes to the fire wall or other one.

Greg, I just did a napa search for M2456 and they show nothing
is the number correct or maybe old?
Thank you
