Would increasing the lbs for the injectors yield any real performance increase?

It was straight out of the Buick Grand Nat. It was also the Indy Pace car that year.

differences between series I & II:
Special notes considering the 3800 Series II engines: The series II 3800 is a redesigned version of the 3800 V6. The Series II block has a shorter deck height, symmetrical design cylinder heads & cross-bolted main bearing caps among most of the major differences it has with it'* predecessor. The Supercharged version of the Series II engine shares the same crankshaft and heads as the naturally aspirated version but the heads on the SC version have bosses machined for injectors, and the crank is balanced differently because the SC version has beefier connecting rods and pistons. The SC pistons are also of hypereutectic casting and have a thermal coating on their tops designed to reflect heat back into the combustion process.
