, the recommended lube for an 820 racing transaxle is 32-36 oz. of Peerless Bentonite (P/N 788067C) plus 8 oz. of either Lucas Oil Treatment or STP.
FLIPPING A TRANSAXLE Addendum
You can modify many 820s into an 017.
The "out the bottom" (now "top" on a flipped transaxle) shift-rod-&-fork for the 820-017, P/N 784359, is still available. You'll need machining capabilities to drill and ream the bottom case (now the top) for the shift shaft and P/N 788072 seal.
Or...once you get the case drilled and reamed for the 017 shift-rod-&-fork, if you want to go the heavy-duty route, you can add a short support tower for reinforcement -- cutting one off another 820 case and welding or JB Welding it to your new 017 "top" case would work. You could then ream the top of the tower for the seal.
Keep in mind that the 017 shift-rod-&-fork uses the large-diameter shift-key collar, so you'll need one of the following 820s that use the large-diameter shift shaft for the 017 shift-rod-&-fork to work: 001B, 002C, 005B, 07B, 008B, 009B, 011B, 015B, 016D, 018A, 021A, 022A, 024A, 025A, 027A, 028A, 029, 030, 032, 034, 035, 036, 037, 039, 040 or 041. If you have a different 820 than the ones listed, you can always install a large-diameter Shifter/Brake Shaft -- P/N 776385 for right-side brake or 776386 for left brake. The large-diameter shift collar is P/N 784352. Shift keys are P/N 792180A.
You'll also need a 1/2"-diameter cup-style welch plug to close off the original shift-shaft hole that's now on the "bottom" of the transaxle -- the pulley side. The Peerless plug, P/N 792140, has been obsolete for years. An auto parts store or plumbing supply would be likely sources.
And...since your pulley is now on the bottom, I would highly recommend a two-setscrew-hub pulley to aid the input-shaft snap ring in preventing pulley fall-off.
