They are plentiful and inexpensive, would solve both poblems.

Start stocking up common repair parts as they may be difficult to obtain on your tour. You should also contact the 4 Australia groups and make some E-Mail pals so that when you get there you will have some contacts if you have problems.

This old truck is supposed to be a bit of a time travel machine. The plan is to build a period style camper (I have old colman lamps and cooker and am looking for a type of heater from back then) for the back and send it to Australia to do a tour. Then across Canada and maybe Europe. The 91 99 carb seems super simple and looks in good shape.

It works very well and delivers good power with decent gas mileage when set up properly. The correct carburetor delivers enough fuel and air to the engine for it to produce the rated horsepower. Most dual carburetor setups deliver too much fuel or too much air for good performance. My advice is to stay as close to stock as possible, so that when problems arise you don't have to wonder about the engineering principals behind the changes that you made. Stock parts are also easier to find and repair. Tom 40 Coupe 04-25-2019 @ 4:58 AM reply profile send p.m. Senior Posts: 1647 Joined: Oct 2009 See the V8 Times classified for contact info. Charlie Schwindler has a Chevy distributor for the engine as well as rebuilt carbs. Catimann 04-23-2019 @ 10:45 PM reply profile send p.m. Member Posts: 18 Joined: Apr 2019 Thanks for all that. I looked up one web site that explained the loadamatic, http://m571.com/yblock/loadomatic.htm It has this quote "All you have to do is exchange the Load O Matic for a conventional distributor to see a marked performance difference." Now I don't need or want a hot rod but do want to take the truck camping and pull a small trailer. For that reason a better distributor and carb would be in order. I also live in BC so mountains are part of the terrain so a little extra power would be helpful. I would like to know how much difference a dual carb set up would make over the stock unit.

It is connected to manifold vacuum. The best way to explain the difference in vacuum is they react opposite from each other. Manifold vacuum is high at idle and gets lower as you accelerate. Ported vacuum is low at idle and increases with engine RPM. You do need a carburetor with ported vacuum outlet. Suggest you contact Charlie Schwendler and ask his thoughts. Tell him you now have a 91-99, he may work out a partial trade, if your carb. is in very good condition. The C in all the numbers is an indication of a Canadian engine. I believe the intake manifold is improper for your engine since it is from 1941 and that engine distributor uses manifold vacuum so the vacuum line from the manifold to the distributor should be blocked off and not used on your engine.

You'll have to change one or the other, or both.

That leads to other interesting questions like what engine do I really have. Looking it all up online leaves me more confused than I care to be. 24 "bolts" in the heads but with water in/outlets. A C1BA cast into the rear of the block. No bell housing. How about I just show you pictures. If you want to see more just let me know.
