The Stovebolt Site Forums The Shop Area Engine Shop Help identifying this engine and master cylinder

Here is a pic of the engine compartment of my 1966 Chevrolet K10. I don't think the engine can be original because there is no listing for a V6 in a Chevy truck in 66. Please help ID this and the master cylinder araingement. I can't find any replacment part that matches this description.

The engine is a GMC, and the master cylinder is a 2wd '60-'62 style with the hydraulic clutch.

Holy crap! I guess I have my work cut out for me. I am assuming it would be best to attempt to run seperate master cylinders for the clutch and brakes. Is this hard to do as a retrofit? I really don't know much about these trucks so this will be a learning evolution for me as I attempt to make it a "driver". I want to get it running and driving first then I'll look into any improvements that need to be made.
Since the brakes and clutch need attention right away, I'd rather get it set up the best way possible. Any suggestions on what to purchase or how to set it up would be appreceated.

Nothing would be gained by having two master cylinders. You would still have the hydraulic clutch setup which leaves a lot to be desired. And it would be a lot of work. You could probably get a master cylinder for the clutch from a truck with a hydraulic clutch with air brakes and then a later brake master cylinder and mount them somewhere on the firewall and somehow hook up linkage. The simplest thing would be to fix what you have and be done with it.

OK, I'll bite, Why does the hydraulicly actuated clutch "leave a lot to be desired"? I always figured a hydraulic clutch would be better. I'll listen to pros and cons.

There are two schools for hydraulic clutches.
1. Those who have never had a problem with one think they are the greatest thing since sliced bread.
2. Those who have had a problem don't want anything to do with them. I am about 35 minutes away from being in this category. I have one in my 89 burban that is giving me fits.

Once the hydraulic clutch is working right, it's smooth and relatively trouble-free. If you want to upgrade to dual-line brakes, try using a clutch master cylinder from a mid-1960's Dodge pickup. It's a single-chamber master cylinder that's about the right diameter to work well with the original clutch slave cylinder. If you plan to stay with the V-6 engine, the hydraulic clutch is going to be a necessity since the throwout fork goes into the bellhousing on the passenger's side, and it would be nearly impossible to adapt mechanical or cable clutch linkage to it.
