fuel-injection is suppose to help the SMALL engines make more power, so we're looking forward to that.

You are way off original topic HIS but... modified 485 fan(twin 2 stroke) on 93 made 93hp at 7800 originally 89 octane 56 hp at 7200 same 38 mm carbs... 493 liquid with smaller carbs(36's?) made about the same at 92 hp but was stock, 89 octane factory tune, about 7800 rpm peak power. Both piston port reed valve design... competitors case reed 500(499) was over 100 hp(105 iirc) on 89 octane gas with 38mm carbs but closer to 8500 rpm power peak.
Not bad for @ 30 ci motors, 2 of which came with warranty. Both liquids docile enough for novice users. Fan was at its thermal limitations... just couldnt cool spark plug(10 series NGK) long enough to stay out of trouble pushing more power thru it.
Find a way to seal up a Pontiac and mods needed to make it a 2 stroke reed valve motor and 3 hp per ci NA should be doable.
