possibly a bit more in it with more tuning?
wonder why its loosing oil pressure as rpm's climb..

Yeah,it does look like it is a bit lean especially with 78/79 jets which would indicate croc is still running a rear pv.
That is the first thing to lose and jet it up by some 8-10 sizes in the rear.
Tuning by using af ratio's is sometimes a bit hit and miss. Using those parameters sometimes you can leave a bit on the table.
I try to tune so that the engine is making the most power and with alloys that can be 13.5 or so . It looks lean but that is where they make the best power.
Some iron headed stuff isn't as efficient and tend to like things a bit richer to make better power.
Well done Dean,there may be more left in that combo yet....
Does Zoran test at 100 rpm per sec?????
