We finally got some nice weather and I made it out to the local 1/8 mile track. Also found some corvette engine covers on craigslist. I think they look bad ***.



The track prep was so so and there were not many slick tire cars making passes, but I made do and laid down a couple decent runs. Here was the best pass of the night.



The street tires just can't hold how hard the converter hits so I had to leave off idle all night. With some et streets it will 60' in the 1.5's no problem. The mph is down a few from where it should be. It needs a fresh set of plugs, these plugs were in for the first start up with nasty 2 year old gas. But with all that said its not too bad for the first time out on street tires and exactly how I drive it everyday. Check out the video.

Details on the setup are:

Stock ls1, stock manifolds with custom 2.5"->3" merge dumped at the axle with no muffler, built 4l60e and 4000 stall converter, camaro posi and 3.23 gears, ws6 wheels with 285/40/17 continental street tires.

Wow, congrats on the pass. That's moving for the little you have done to it! What's the race weight? I'd like to see what it'll do on a DR or slick.

 

Race weight is 3400 lbs with me in it, I'm 215. Still has both bumpers and a tow package. On a drag radial I have no doubt it will 60' in the 1.5x range. Finding that extra couple mph with a good 60' and I don't think 7.6x is out of the question.

 

Nice! That engine fits in there well. Almost looks like it came from factory that way.

 

That's impressive. Nice looking engine bay.

 

Thanks guys that was exactly what I was going for.

 

Damn, impressive for sure. If you did that you'd be knocking on the times I ran with my bolt-on LS1, that's awesome for a truck!

 

I probably won't be back to the track until I get a good set of drag radials to throw on, but I've still been contemplating ways to make it faster without adding any power. What do you guys think I should be running for mph in the 1/8th at 3400 lbs race weight and my current set up? I think the mph is low but I want to get a good idea of where it should be. I'm in the process of designing an air box for the intake to seal it up from the hot underhood air as well as changing out the plugs, do you guys think it has a 7.60 in it if I can get the 60' down to a 1.5x?

 

Forgot to mention I am also going to remove the front sway bar next time out to hopefully aid in a little better weight transfer. Just did a little searching around it it looks to me that if I can get the truck to run a 7.60 that should be right at 11.99 in the quarter.
