Can you get your hands on some sticky tires????
Check my sig and you can see what I am running... Its similar to you [my engine is bone stock and I still have stock H pipe] and I run 13.11 @ 102 MPH on slicks.
I have raced a a few LS1 SS cars from around town.
Most recent one was a 1998 SS SLP [its an LS1] 6 speed had the ZR1 style rims.. I know it was a bone stock one but had the factory SLP cat back... Anyways I was on my Walmart Radial GT street tires and I started pulling away ever so slowly from a stop light till we let off around 60 MPH. My car hooks on its street tires though... 27.5" tall 255s w/ a 9" contact patch
Next one was a red 2002 SS Camaro Z 28 convertable with the weird checkered flag graphics. This one was an auto. [we asked him] Got eachother at a red light. We left on the green, and the same thing happened.
I started pulling away slowly and so he just let right off.
I hate when perople do that.
Last one was a 2000 SS Camaro 6 speed. Dunno if it was a factory SLP or just some aftermarket exhuast, but it's exhaust wasnt stock... My cars mods were all the same as the sig/webpage but I had not put the 3.73s or the 65mm T body in yet.. still had the 3.08s. We left the light slow... and while rolling he nodded and nailed and I was floored as soon as I heard his car burp. He had his nose in front of my nose maybe 2 feet.. and it just stayed that way alll the way up till about 75 MPH till we backed out of it it.
Stock MAF on your car? Jerk the screen out if you havent. Sway bar still on? Yank it off. And if you can get your hands on some good sticky tires I think you'll take him off the line and he will be playing catch up. Street tires... If he holeshots you, its probably game over.
