06 Silverado with a 5.3 with 224/230 on 114 on 200 shot, 4l80e 3600 stall with 4.10 has went 7.13 at 94 cutting 1.57 60ft. Need to get in the 6’s before March!

 

Is it a LM7? With 706 or 862 heads?
this 200 shot on 93 octane?

 

862 heads lm7 yes 93

 

With the metrics in the op, it either needs to pick up on the 60' or make more power on top end. The 60' is within range of what I would expect for the setup dependent of weight. The mph seems a bit low for the et/60' though so I'd focus on that. Lots of variables for that setup on tune, induction and exhaust that could affect it falling of on the top end.

 

E85 and more timing and spray?

 

Sounds like it’s running great for the mods you have listed. Since you’re the one behind the wheel, where do you think it could use improvement?

 

Do you have a recent time slip so we can see what the numbers are?
