Ok, we've all seen it before with the hotrod powerstrokes and cummins, but I saw a guy take it to another level the other day. The last time I went to Ennis for Friday night test and tune, there was a dude in a newer Z-71. Looked like 16" Ralleye wheels off of a 95-96 truck. Hit the box, purged, we are talking massive shot of , then proceeded to melt rubber, and we are not talking about a regular burn out here ladies, this was of epic proportions. Then he cut loose at the line. I'm guessing he launched in 4 HI, then went into 2. All this excitement with this truck, we didn't even see what he was running. A new Cobra is over there w/ slicks and other Bull @#%*, Anyway, they run and the truck blows the slowbra out of the water. No times at the end of the track, I was a little pissed but oh well. From what I hear the guy had a 5.3 w/ ls1 heads and cam, all the boltons you can think of and the . Big converter and big gearing all around. this thing was horribly good looking too. Has anybody seen this truck or one like it around?? Does anybody else do this either??
I was going to work my 1500 Z71 LT over (as in my sig) but opted not to for many reasons:

I need a stronger 4L80E trans vs the 4L60E (even fully built, with what I had planned would blow up a 4L60E).
the stock 8.5" wouldn't take a 2Hi launch on slicks
10.5" SF axle is $2500
E-Locker for the small IFS isn't available yet
Only avail in ext cab

I thought of doing a medium compression 422 around 9.5:1, stuffing 7psi into it, running dual stage nitrous also (75/125), obvioulsly heads/cam too. While you can get the motor to handle it, the trans and rear axle aren't up to the task.

I am going with a Duramax Diesel in the spring Better motor, MUCH stronger trans than the 4L80E, 11.5" rear axle, oh and 20+ MPG when cruising. Fully done will make about 750rwhp/1300rwtq...
