Travis,

Thanks for the advice, I'm going to dyno it first, with A/F sensor hooked up
to it, and see what she's doing, before deciding whether or not to redegree
the cam...

I'm running a K&N FIPK...it's the open element 14" air cleaner...

I run at the Texas Motorplex... elevation isn't a concern there...

Another thing, is that I need to get a better torque converter, and a shift
kit... as a couple of times when I'd shift from 2nd to 3rd, the tranny
didn't shift until I let off the gas a little..so, that might have some
effect on mph at the end of the 1/4 mile...

Later,
Tom "Slick"

Hi Tom,

Like others have said you must be spinning off the line because 2.4 or even
2.3 60' times aren't that great. That being said, in my R/T I can never run
better that a 2.3 at Firebird in Phoenix because the track is always so
greasy. I have ran a 2.1 at the Tucson track. So the track you are at
might have a lot to do with it. What is the altitude of the track you are
racing at??

MPH is usually the best indication of HP, because even if you spin the tires
you can still run a decent MPH. Your MPH of 85 and 86 means you are way
down on power, especially given your mods. Other people have offered up that
your low end is off, but I think it's your top end. Your truck is falling
on it's face after the 1/8 mile. For example, look at Run #5... at the 1/8
mile mark your MPH is 70.62 at the end of the 1/4 mile its only 85.29.
Unless you let off at the end, something is wrong. When I used to run
around 70.0 MPH in the 1/8 I would still run over 88 MPH in the 1/4. What
kind of air intake or air filter are you running? Your truck could either be
starved for air on the top end, or it could be leaning out at the top end.
Can you borrow an air/fuel mixture gauge from someone and then make a run?

Good luck,
