I took the spare tire out, and got in to some better air and it went 8.51 in the 1/8 with the racestars, I wasn't going to fool with it but really thinking about picking up a verter like yours, how to you like it for as town driving etc. Oh btw of subject got a 69 Camaro with a ls2, comp cam, trick flow 225s, and it went 6.78 in the 1/8 first time out pretty pleased still needs some suspension work and a tune. THANKS!

What the dyno graph doesn't show is what concerns me for truck application with oem stall. The torque plotted on the graph begins just below 4k where LS9 cam is showing less TQ and looks like the gap widens as the RPMs decrease. A member on here that installed the LS9 cam said the bottom end is soft. Seems that a custom grind with similar specs and tighter LSA would be better for a 5k# truck...if you didn't want a converter swap.
I can't figure out what people are talking about. My truck drives way better with the ls9 cam. We took a trip to the mountains last week and it had no problem going up grades at 1200 rpm in 5th gear. The power band is way smoother than before.
What I did notice on the tuning side is that there are plenty of areas in the main timing table that are really low. Timing is added in the vvt tables with the stock cam. Once all the timing is added back to the main timing tables the truck drove just as it did before.
