Great post, look forward to reading more responses.
I declined upgrading from stock 10x2" drums on my 69 coronet(original 6cyl, now a 496") and went with bigger 10x2.5" rear and Everything New 11x3" front drums up front(intended to build an A12 replica) w/manual brakes.
Always stops fine with minimal fading on hot days. The only times I had issues was when the rear axles kept puking, leaving me with essentially front drums only, which really sucked.
Brand new replacement 11x3" drums are available through NAPA. Thought i'd share.

I saw that article and paused when I read that as well. I just shrugged, as I don't know what "custom arched shoes" would be???? Check these guys out.... http://www.musclecarbrakes.com/index.htmlDon't know if their stuff is any better than standard raybestos material??. There was an article in Muscle Car Review a few months back, they did a test on a set from these guys and said they worked remarkably well. (???)

Back in the day, No brake job left the shop without proper arcing of the shoes. Amco made a special machine to surface the shoes to the exact diameter of the drums and leave a uniform finish.. That meant that the operator and anyone in the room got a faceful of asbestos.. but hey this was 1968.... I havent switched my b body cars to discs yet, the shoes will stop from highway speed fine once or twice then will need prolonged cool down.. I do own a 68 Chrysler 300 with a disc conversion and it stops awesome.. Way back, I used to run Lakewood Velvet Touch shoes on my Hemi Runner and they were deadly until they warmed up, then unbelievable stopping power..

I know disc brakes would be the ticket but this car is a completely restored numbers car and I will need to keep it stock looking......it has a very strong 472 with a solid roller cam putting out some good steam (approx 600 hp per the dyno)
Has the numbers 426 been stroked to 472?

I also assume my 68 rr hemi has 11x3 inch drums in the front and 11x2.5 in the back? I also plan to look carefully at the brake drum surface and make sure it is in tip top shape.
I'd check those sizes if I were you. You know what they say about assuming things.
I think a well set up set of drums, will stop fine. And I don't buy into someone trying to reinvent shoe arch.
My daily driver until recently was a 68 newport with drums all around. As long as I kept them adjusted tight it stopped great.

What part number, I was just there two months ago and they couldnt find me anything. I thought they would have something and I figured theyd have a reasonable price.
PS I know your in CT, which NAPA did you get them through? And do you remember the price?

Yep we had the grinder on the back of out drum/rotor lathe. It quickly went out of use because disc brakes up front and flat rate. But grinding the shoes to fit the drum is the best right way to do it. Ron

Ron do you have the 63 converted to a dual master?My kids 62 300 w PB we did a 69 C body master on.Its for a 69 C body with power drums.It stops great even at 100 plus.He does have the factory 12 inch brakes on it.Its amazing how good it stops even with the goofy dual whl cyl setup they used.Rocky

i never remember the drum brakes being that bad 40 years ago as mine seem now. i don't really want to convert to discs either. what would you recommend for a master cylinder? linings and master are new but the master just doesn't seem right. it has manual brakes.

There is a company making hipo shoes for drums.Ive seen them advertised but cant recall the name.Believe I saw them in a Mopar mag.Shoes are supposed to stop better and not have as much fade.If its not a show queen Id go discs.You can always just put it back to stock.My 65 I cant believe how well it stops with discs.I always though the drums were Ok.After the change its a different car.The C body masters seem to work great with either disc or drum.Rocky
