I wanted a big tach, but not a monstrosity on top of the dash. Couple that with long winters and access to machine tools...

 

ran my truck 2 weeks ago got the best of 12.3 @ 110 n/a it was cold out mid 40s traction wast that good pretty sure its got a 12.1 or a 12.0 in it

 

Sick build! sub'd

 

I managed one run at New England Dragway last night before the rain. It was a mad race against time to swap my tires, pass through tech and line up to race. The skies were an angry grey and it looked as though it may rain any second.
My time was 12.8 @ 105MPH on motor. The skies then opened up and I changed my tires in the rain before going out to eat. I am so pleased with this time for what is considered a baby cam and budget, mild setup.


After reviewing the logs and time slip, I think I can do better... My 1.9 60' isn't what I expected and the log shows I was 75% throttle off the line and then WOT once rolling at 6mph. I believe I can hit WOT out of the hole.
Another area of concern is my spark advance and knock retard. Once I hit WOT and 4200 RPM in 1st gear, it logged 7 degrees KR and 12:1 AFR. Once in second, AFR went to the commanded AFR of 12.9:1 and KR decayed normally. I need to sort that out. I'll post up the log file if someone wants to take a look.

I went to a chassis dyno the other day, had an awesome time. Ran in 2nd gear, converter unlocked. 345 HP. Here is the graph.

 

what tire size do you have on those tahoes?

 

255-65-16 BFG Long Trail Touring

 

ok thanks. I got the same wheels on my 89. same as your build but mine is a 5.3. good looking truck you have there. I still cant decide on the color.

 

Been away for a bit..

Thanks for the pics of the gauges. I am wanting to do them so bad... Was it a pain wiring them in or is it a cut the wires from the pigtails and connect type deal? I would be very greatful for any info you could give me.

I like you build man. I have an all aluminum 5.3 in my '96. It had a basic tune and I was (and still am as its not a daily) impressed with it. It is very quick. I am going to do a cam, converter and put it on nitrous and redo the wiring harness this winter if all goes as planned

 

Looks awesome Scott. Hopefully I'll catch you at the track one of these nights.

I bet this truck has more in it than you think... id bet you can knock your 60' down to a 1.7x, which would put you at 12.5 or better in the long run.
