That lists the 92-93 L67 as having 28lb injectors. I was under the impression they were 21lb. Anyone know for sure?

Very interesting.... a good read.

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

don't take my word for it, but I don't really think it would unless you have a lot of mods because I *think* the only reasons the SC cars have bigger injectors is because they force in more air, which requires more fuel. So the injectors have to be able and put out more fuel at high throttle.
Definately a good site, I added it to my bookmarks.

That'* my take on it too....a friend just added a supercharger to his Mustang and he purchased larger injectors for that very reason....

Good info. I've always wanted to know the stall speed of my TC.

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.
