Tried a search with no luck, saw a post from five years ago but it left the result hanging and did not say which part number was used.

My new engine will have four Weber 44 IDF's and zero vacuum sources.
My solid lifter cam would have almost no vacuum anyway.

So I need to find a manual Wilwood or Tilton dual MC setup with adjustable bias.
Want a hydro clutch too as I've had some bad days with Z bars.

My rear is a Jag IRS with Wilwood calipers.
Now my factory front disc are probably a bit small, but I cannot go too large as I intend to keep my 15" wheels.
Front rotors and caliper upgrade should be fairly simple, it's the MC issue that is being difficult.

Somebody must have done this before, hard to believe I would be the first.
"Universal" kits, but some are going to fit better/easier than others.
Looking for suggestions, hopefully from someone who has actual experience.
Any auto-X or road-racers here?

This just became a higher priority.
Mom had a stroke today and the El Camino is the only car I have with large easy entry doors.
So need to get it on the road ASAP.
The bed may be necessary to carry a wheelchair for her.
Selling several other non-Chevelle projects to fund rapid completion.

When I did the 12" disc brake conversion on my 68 Chevelle Convertible I also wanted to try to maintain the manual brake setup the car came with but get it to approach the feel of power brakes. I used a 75 Vette Manual Brake master (1" piston) and the 1985 K20 Suburban 3-5/32" piston calipers (use a die-grinder and cut a groove in the horseshoe for the brake hose) and Raybestos BruteStop pads (Friction/edge code "FF"). I originally used an adjustable proportioning valve in the rear brake line, but later realized that even set at minimum it still seemed to be trimming more pressure than it needed to. So just as an experiment I took it out and found the brakes were great that way. Right now I am working on another Chevelle to convert it to manual because I have a healthy cam in it/low-vacuum and I need consistent braking. I am going to use the same 85 K20 3-5/32" calipers, but I am going to try the Wilwood 7/8" piston master cylinder to see if I can make it brake even better than the Chevelle convertible. However although the BruteStop Pads are no longer available, Raybestos now has the Element3 pads (#EHT52) and upon ordering some I see the Friction/edge code is "GH" which is even better than the old BruteStops which will mean even better braking with less pedal force. To save some $ on the master, it might be possible to use the 1975 Ford Bronco 7/8" piston master cylinder, but at the moment I am not sure if the mounting bolt holes width is correct to mount it (which is why I ordered the Wilwood).

Thanks for the reply.
Limited budget at the moment.
Need to look into what I currently have for calipers.
Determined to stick with 15" wheels.

The Suburban calipers work with 15" wheels. Vette Master is currently $26.79 on wholesale closeout at Rock: RAYBESTOS MC36367
