Yep, which is fuel quantity per unit time, which relates directly to work per unit time, which is what horsepower is. this you need >to know so you don't have to run your injectors static at WOT and Max >RPM... Pulsewidth will tell you how long the injector is open so you know >how much fuel is being injected... Fuel quantity per revolution, which relates real directly to torque. I agree with what you say about what you are checking for, tho.

BTW the Olds F85/Cutlass and Buick Skylark were closely related, but i don't know if they used the swing axle/transaxle setup or not. Interesting (to me) side note to tese cars is that this is where Buick intro'd the old aluminum 215 V8, which would become the 231 V6 we all know and love. Even better is that Oldsmobile offered both an NA and a turbocharged version of that engine, complete with some kind of anti-detonant fluid injection! And this was still no later than '63, as in '64 all these cars became standard A-bodies, sharing a platform with the '64 Chevelle. Had to jump in...
