the hydro's are set up to turn either way by reversing the charge pump.

I was going to mention this also.... Besides, the gears don't care which way they turn, so what do you mean by a "custom gear drive"?


While I'm here:
In the hydrostat, you didn't really do anything that would have solved the cavitation issue that I can see. You say you added a weaker spring to the charge pump relief, and a stiffer spring to the pistons in the pump. Then you refer to the cylinder block as "Part D & E" instead of by it's name. You say that you "milled out the oil passages", except there are no "passages" in the cylinder block.... Then you go on about changing some other stuff that really doesn't make sense at all for what you were trying to accomplish.

Lets move on to the engine that you are describing:
First off, a SBC turns counter-clockwise stock. All motors are labeled from the rear. From the rear... they turn counter-clockwise factory. Now, lets skip the description err that was made and assume that it is true that you are turning the cam opposite rotation of the crankshaft..... Why then would you need to do a reverse cut of the gear on the cam? It would have mated with the stock dist gear just fine.... but wait, you said you used the stock gear. How does that work? Reverse cut gear on the cam mated to a stock gear??? Yes, a custom cam would have had to have been made, but only because the firing order is now basically backwards. Which would not have required a custom cast, only a custom grind which would would have been ridiculously complicated for even the best of cam grinders.

Listen, I'm just going to come out and say it. Your answers are kind of sketchy and mostly vague. I agree that this machine exists, but I'm not convinced that you are the builder. All the info that you have posted can be found in various articles and sites out there on the old WWW. I will admit, with the exception of some of the pics that you posted, but I also know that ol' Google can't find EVERYTHING. Avery Allred's phone number is listed on his site. If I call it, will you answer? I'd like to have verbal confirmation that it is indeed Avery making these posts. If indeed you are the owner, I will make a public apology and we can move on. Understand that I, as a moderator and trying to validate the authenticity of your claim.
