Another "what should I run"
Since it's looking like I won't have my engine back in my car before the track closes I'm curious as to what the upgrades I did should do to my times
With an L31 .40 over, 10.5:1 compression, 2.77 gears, LT4 hot cam, 1.6 rockers, EQ Lightning 180 CC vortec heads, Stealth ram with 52mm BBK TB, and 21# injectors untuned I went 13.91 @ 101.1 with a 2.155 60'.
Since then I upped the compression to 10.7:1, upgraded to 28# injectors with a mail order tune (I know Dyno is better but its all I could do for now), balanced rotating assembly, and 3.90 gears.
I'm hoping that would get me into the 12s...

Re: Another "what should I run"
Auto or manual? What tire setup? Improving the 60' alone should help tremendous.....that combo should have more then enough for a 12.
