Ran 15 passes tonight, October 2nd. Best pass was a 15.15 @ 90.5 MPH with a 2.29 60 ft. I was in fact getting some KR at the top end, but I'll work that out for this Saturday's track day.

 

Not too shabby.
What does the AV weigh?

 

Thought 8.1's were 31#s

Nice times, you need a converter for that beast.

 

8.1 marine's are 42lbers.

 

It weighs in around 5800 lbs I believe, plus me (I'm 210). I'll know more on Saturday when I run again, gotta hit the scale.

 

Those beasts are pretty heavy! Tweak your tune.....go 14's!

 

That's exactly what I plan on doing on Saturday. I know it's right there...

 

Ok, so there 8.1 marine injectors, not gm 8.1L.

That thing needs a diet! Or FI

 

good times for a big av.
i think those heads are holding you back though.

 

Actually, I had LS2 heads on there previously but one of them had an issue so I was forced to swap them out. The 5.3 heads give it more low to midrange torque without the need to spin to 6500.

These trucks run in the high 16's, low 17's in stock form. I can't complain about low 15's with it. I might worry about it if I were planning on keeping it, but I've got to sell it. Already have a thread up for it and whatnot...
