1967 Chevy Impala 327

Hey,
I'm Ryan. I have 1967 Chevy Impala 327. Has four drum brakes all around. I ordered Right Stuff Detailing front-disc conversion kit. (https://www.summitracing.com/parts/rsd-fsc65dcc). New brake booster, master brake cylinder, etc... Kit works well, happy with it. I ordered a rear disc conversion kit from Right Stuff as well. I'm not an expert and not a mechanic by any means; so bare with me. Do I need to upgrade brake proportioning valve/distribution block in order for disc brake setup to work properly? Also plan on doing an engine rebuild when i can afford it. Any and all advice would be greatly appreciated. Willing to learn and want to do engine rebuild based on what the car will be used for: street use and light touring in Montana. Looking forward to everyones' input and advice. Thank you.

Ryan

An adjustable proportioning valve is often included in kits to balance front to rear braking depending upon your suspension. It is adjustable because every car is different in it's set-up.

If your car has soft springs and worn shocks too much weight can be thrown forward of the cars center of gravity; unloading the rear tires, which first lock up, then skid, causing the rear end to try and pass you. On a lumber wagon it wouldn't be a critical as it is on a marshmallow tough full size car's suspension (it was all about ride quality back in the old days not performance so you could get sea sick in some of these big barges during turns and frequent stops).

Hey Big Dave,

Thanks for all the advice and future advice to come! This 67 impala was a gift to me from one of my dad's retired friends. I plan on doing a full engine rebuild on the 327 engine with quality components, new tranny (700r4 i believe), and body work and paint when i can afford it. I'm not an expert and willing to take advice from people! I research anything and everything before applying the idea to the car. By all means, please feel free to leave your advice about a performance engine rebuild, trannys, camshaft systems, etc...Appreciate all the help gents!
