New Track Time for my 69' C10 with LQ9 6.0L LSx Swap

[matthew20061]

Well I went out to the track yesterday and got some first new times for the new motor built in my 69.
The second run was the best at a 13.54 second 1/4 mile @ 100 mph. The tune is pretty rich so I think its got a bit more in it as well as headers and air intake upgrades.

In truck camera:

Outside camera:

The engine is a LQ9 bottom end with L92 Heads, and an LS3 intake with 90mm TB. It also has a comp cam. I was pretty happy with the time but I think its still got more in it.

Dang!! Your truck looks and sounds sharp!! Nice run as well.

[19seventeeCustom]

hell yea, that nice!!

Truck sounds really good too!!

It def has 12's in it, what tire are your running? it has significant wheel spin so if you can get your 60' down the big number will FALL.

I figure the truck should be making at least 415-430 rw, through a 60e? have you had it dyno'd? I know it should make enough power to go 12's...good luck, looks like a fun project!!

I'm running 15x10 rear rims with 275/60/15's made by Firestone "Indy Hawk 500 series" It hasn't ever been dyno'd as there aren't really any up here. I definitely think its got potential to be in the 12's. The track wasn't prepped at all that day either I hear so it was really slippery. (some guys where spinning all four tires in 4x4 that usually hook up is what I heard). I'm going to try and get the tune dialed in more and see where it goes from there.

nice ride! I am in the process of building a c10 right now, doing a budget turbo 5.3 setup.... your times even with the wheel spin give me hope of making my goals! Yours has so much more in it!

What are you running for suspension?

You dont happen to know my buddy Kyle Q. with a black trans am do you? He lives there in Anchorage also...

I love the sound! I get a kick out of the ashtray opening under acceleration

Thanks! I know it had more in it. We will see this next year what it does I think my tuner has it tuned in better now. I know of some trans ams around here but don't know anyone with one.

Whats your AFR/Timing at in the tune now, you tuning it yourself, and what software ya using?

Sounds like you can make up alot of time in your trans tune too, is torque management still enabled? Sounds like it is but hard to tell, and did it go into overdrive before the traps or did you let off the throttle?

No I have a mail order tune guy doing it. I have HP Tuners as well and mess with it a bit but I'm not any good at it. At the end of the first video I let off if you keep watching in the second run I hold it down the entire way. Yes there was a lot left in it I believe it was running really rich at WOT. Anyways now I have a better tune and AFR setup and the track season is way over up here. I guess next year I'll get another run in.

[VDOG]

That was a cool run.

[C20-67_N_MO]

Very cool.

Looks like its COLD up there already huh?

Good luck next season!

[Ackattack]

What gears are you running? It looks like there is quite a bit of potential for improvement.

I am hoping to run high 13s in mine when I get it to the track on some slicks. We'll see though.

12 Bolt Posi 3.73 Gears is what it is running for the rear end. I ran the truck on a base tune my tuner sent me to get it up and running so I am sure with this new one it will run even better!

Man that gives me a lot of hope like to know what suspension your running.

Stock suspension! LOL Its lowered with CPP drop springs and shocks other than that its stock and seems to hook up pretty good just needs some slicks and I'll be in the 12's! Haha

[sleepertruck72]

Nice truck ! Looks like that was a fun time on the track

Put a cover on your box, or bed, whatever you want to call it. That thing is like a parachute on it's side as far as drag is concerned. I'd be intrested to see back to back times with that thing coverd and then uncoverd. I'm thinkin the difference would be signifigant. Opening or removing the tailgate would be easy and free also.

Saltflats guys disproved that years ago.

Remember the tailgate nets that improved milage? Didn't work.

However, opening the tailgate will move a bit of weight farther back and help with traction. Not much on these trucks, but some of the el caminos that had big heavy tailgates will see a big improvement on the track.

Great looking truck! Great engine setup, was thinking about the same for my camaro.

Agree with this guy, the bed/tailgate has no affect at the track

did you use the go pro camara ?

Yeah slicks are definitely needed, the camera was just a Flip Mino jammed into my headrest but it worked good!

Yeah... definitely agree tailgate had very little gain and same with the bed cover.

[jessemthompson]

Off topic, but I have ran at that track when I was stationed at ft Richardson a few years ago. Track prep wasn't the greatest, but it sure is in a pretty area.
