Saltpeter, sulfur and hardwood charcoal. I'm sure you don't need the formula, but let me know if you do. Of course this doesn't work nearly as well as the powder you're used to, but it will explode and you can propel rockets with it. Actually if you'll mix it with talcum powder and sugar it will do pretty well in rockets. I doubt any semi-automatic would function as designed with black powder, but I'd bet manually operated guns would shoot...until the barrel was ruined, that is. You'd probably have to clean the gun after about every 5th shot. Maybe after every shot.

Warm water dissolves black powder salts in a hurry! Fortunately, the oldtime mountain men and "long hunters" who used BP guns carried a ready-made supply of that stuff. It was sort of yellow colored most of the time!

The late Dale Walksler (Wheels Through Time Museum) had a great theory on old engine start up. He said that the engine didn't care how long it had set only that it was hot when it was last shut off. Some of the engines he would start had been setting foe 40 or 60 years, he would place a Hot Plate under the engine and allow the oil inside to get warm once again. He started many engines using this method.

The point here is I doubt that cranking an engine that had recently been run would be as hard on internal parts as and engine that hadn't been run for years. Personally I have no problem cranking an engine until it starts and the oil pressure comes up. I do however fill the oil filter when changing the oil prior to starting as most oil pumps pull from the filter first. (off my soap box)

Thanks to everyone for their responses! I’ve decided to go with an electrical fuel pump with regulator and return line for this project. I doubt I’ll see 100,000 miles out of this engine but if I ever decide to run boost I’ll be halfway there with the fuel system. I just couldn’t wrap my head around what the mechanic was saying. Thanks again to all for sharing their opinions!

If you use a small PULSE pump, you can do without the return line. The stock fuel pump will pull fuel through the PULSE pump so it can only be used for priming, it's a safer way to run electric pumps. Just wire it to a momentary push switch, once primed, you won't need it again. If you plan to run electric all the time, be sure to add an oil pressure safety switch which shuts the pump off when the engine has no oil pressure. Chevy VEGA's had such a switch and it's what everyone uses.

Praetor I would think that choking your 383 every day wetting it with gasoline would be more harmful than worrying about oil supply. The bearings have an oil film that protects until oil gets there. Same on the cam.

A little apples and bananas but, my old '95 12 valve Dodge Cummins has (generally) been starting on the first revolution for the past 26 years and 300,000 miles. When its been setting for a few weeks and not cranked, I sometimes think about dry starts but so far so good.
