Well per the Gonkulator, the aluminum actually is making it go SLOWER.
Here's proof:
Your 0-60mph time
12.0 sec stopwatch (LOL, super accurate....)
Gonkulator run, your 66 c10 even allowing for a super-slow 1-2 shift:
Torq 259 at 2900
Powr 192 at 4400
2.42 60ft
11.77 at 60.5 1/8 mile
18.59 at 70.1 1/4 mile
11.56 0-60mph
So this proves that the aluminum is slowing down your 0-60mph time by almost half a second!
