I found that running a stock S10 P/S hose (which has the same metric o ring ends as a newer style FSJ) worked fine in my old J20 after I swapped in a new style gear.
Oh and for the record, a 4.3L V6 powered ZZ code J20 seems to move down the road just as good, if not better than the stock 401/th400/QT did...

Good to see you got it running. That 4.3L makes more power than most of the smogged out V8's of the later 70's and 80's. Most carbed 80's V8's (All makes) made 120-160hp. EFI fixed a lot of those power issues simply because they ran cleaner, so the cams and compression could all be bumped up. Which is why you can gain so much power from say, an 80's AMC 360 just by swapping out the cam. The stock cams were very small to help pass smog. Plus timing and all that was jacked up to make em run cleaner.
Good to see you got it running and will be interested on fuel economy. You should be able to get upper teens pretty easily on the HWY.

Think you have that backwards. You want shorter gears with an engine that has a narrow power band so you can keep it in the power band. An engine with a broad power range (Like a big block) can live with very long gears as it builds torque across a very wide RPM range.
In Blakes case his J20 has 4.10 gears, which works out perfect for stock tires and the overdrive of the 700r4.
Big blocks have torque to overcome the high gears. The fuel injected V6 is bottom end torque biased as well. Straight 6 makes bottom end torque and lives quite well with even 2.72 gears.
