Are you going with liquid propane injection? That ought to give you a really cold and dense air/fuel charge to the cylinders. It'll be interesting to see how you tune for that high octane fuel and how the performance of the engine changes.
Edit to add I own page 5!

because of several glitches i decided , that this engine will get a normal sequential propane system and not the LPI system. 1. there is no datasheet for emissionvalues for the Fiero and without it i could drop in emmissionclass to a more expensive level (taxes ) 2. LPI Injectors have to be very next to the intake valves with the normal injectors i have a hose coming of the injectorblock that goes to a small port i can drill into the lower manifold for each cylinder. with standard fiero intakemanifolds there is simply not enough space .
3. LPI systems require an propane pump that pumps the liquid propane to the injectors and ive a lil "spaceissue " in the Fiero trunk.
our propane buthane mixture is rated at 116 octane so i guess ill set my ignition timing to 14degree for first testing. I also add a exhaust temperature gauge to see what "window" is possible .
my buddys formula will get an 3800 na engine and i guess that is a very good candidate for the lpi system. I guess ill start a 3800 rebuild thread soon

3800 N/A out of an 90-92 Transsport L27 i guess. a friend of mine bought it with 2* 4T60E for 150 Euros
plans : several variants possible - staying with a stock N/A - turbo it . - supercharge it - stay as an N/A but with 9.5 piston 1.8 Rockers , perf. crank and some more goodies
here it comes
opened it up and it looks surprisingly well , in fact the heads , lifters and rockers look brand new
waterpump looks new to me too
buuuut heres the 1st thing : no gaskets unter the lower intakemanifold to the heads and keep tight on ur seats they mounted the Head without a Headgasket . And for sure this engine was running for a while .
several years water in the cylinders cant be good
cleaned it a lil
new freezeplugs and take a look to the teeth of the flexplate its also brand new
opened the bottom to pull the pistons and check the bearings
crank is very good but all bearings have to be new .
24800 miles now on the 3.2 60° V6 of the beginning of this thread now . big xmas present of my car ... fuel lines are frozen now because i dont use the fuel system long enough and here is 13° below zero ...
