I think it was something like 11 quarts in one of those tankers.
We adjusted the pressure regulator at the race track many times. Adding or removing a shim made a big difference on the gear change. Too much pressure and the little 283 would bog down on the 1-2 shift or maybe it was the 2-3, I can't recall that detail....too little and it slid...... I used spark plug washers and a big wrench.....Was a nasty job at places like Atco in the sand......but then so was R&R' ing the driveshaft at every race....we had no towing hubs....
Work is slow....can you tell....LOL

Our hydro had the disgusting habit of blowing out the seal between the crankshaft flange and the flywheel and dumping the entire 11 qts. of ATF on the starting line. We called it "Old Leaky." This happened at the trophy race at the 1961 AHRA Nationals at Green Valley (Texas.) Don Biggers went on for the win. He had us covered by about a full second...
AHRA cleanup crews were not amused....
I used the spark plug washer "trick" for mainline pressure adjustment and ended up coil-binding it (un-knowingly,) and I got my first lesson in physics as regards the compressibility of fluids... they aren't.
Blew the whole end off the oil delivery sleeve. Now, we had a 2-speed.... 1st and 3rd....
Live and learn....
