Colorado C2 project

I think those are the numbers from the D8-4 rear caliper. The D8-4 front looks to have slightly more piston area at 5.56 total with both pistons having a diameter of 1.88.



Either way, let us know how you make out. I've found the only consistency in these cars is that every one of them is completely different!

Oh yeah.. updated...

but wouldn't it come down the volume? or is just piston area? I have a set of stock brake calipers too.

But the Wilwoods look cooler even though I cheaped out for the non-powder coated silver ones. Saved $200.

It's some black magic that I only vaguely understand. On paper, smaller bore means higher pressure for a given pedal effort. But pedal travel and pedal feel also come into play....as does volume of fluid being pushed to the calipers. Big pistons in the calipers requires a higher volume of fluid. Bottom line is there is a happy middle ground, the calculations for which I'm certainly not qualified to explain. If you call Wilwood, depending on which tech you get, they do a pretty good job of explaining what you need and why based on what other equipment you're running.

Awesome. I love the 66 Impala.

C2 update...

Sent my diff off to Gary still waiting ....




slapped on some magnaflows while they were on sale.. little more rumble...





Picked up 2 327s ($100) going to rebuild one on the cheap and slap her in my c2. Since my current 327 leaks like a sieve. And probably LS swap down the road.




Got the 327 back from Machine shop with .30 over cast flattop pistons installed..







Decided on Brodix 180 intake as Cast heads setup for roller cam.



going full roller rocker...1.5s summit s




As for the Cam (going roller)

Here is the spec for the Roller cam...
