We still got quite a bit of room to work with on the fuel. The truck will run 11.20s or better on this nitrous jet once we get the tune cleaned up
The truck went 11.74 at 115 the first pass. We added a degree and picked up 2mph. So it's a little light on timing also.
More nitrous, lose some weight...10 second ecsb??? Are there any of those around here???

yeah there's a 2wd 10 second ecsb turbo 5.3 around here somewhere.
is the 250 shot guess correct? who speced the cam? not the typical single plane cam that i've seen alot of guys work with. then again i havent paid much attention to the typical cams that single plane l92 setups run. larger exhaust bias and lower lsa is what i would expect to see (which may be why i dont spec cams for a living lol)

On the phone with the cam guy right now for a cam more suited to this setup

good deal. i think theres alot more MPH in that combo with a cam better suited to the heads. my lil ls1 with a rinky dink cam and patriot heads averaged 118mph on a 125 shot. i could never touch a 60' time like this though. a single plane on l92 heads and a 225 should be into the low/mid 22x mph area. a couple small tweaks and you guys will nail the 10.x time slip in a 2wd ecsb that i gave up on.

Your cam don't look to bad Tyler, what you need is some better head flow, the intake and cam will work together nicely, but the ex runners will choke it bad at that high rpm.
