this is the 2nd time out & nitto's just wont hook, but I had fun in my 4100lb AC, overdrive 68 Charger, it was a spin fest again, you can see I wrote the density altitude down for each run, & the what the car should run at sea level air, it was hot & we had a 20 mph head wind, still could not do any tuning cause NO traction, but I am pleased with the MPH.

I used to have a fox body mustang that would run 12.30s on slicks. For my street tires I had run Nittos(275/50/15) and BFG plain old radial TAs in the same size. The nittos hooked better on the street but I ended up having way better luck at the track with the plain old BFG radial.
I have had great luck with the mickey thompson drag radials on my Barracuda.

The Nittos are a great street and highway tire. I've found they don't stick too well to a rubber coated surfaces. I go to the track so rarely that it would be hard for me to justify shelling out $ for a set of dedicated slicks. They've closed nearly all the local tracks around here. It's over a 2 hour ride to the closest ones.
Those are some very good times for a heavy car with those gears and limited traction. Nice build.

This is my daily driver & I agree the nitto works great for that, & so far made it to the track twice in a years time, new slicks & rims are out of the budget right now, disc brakes in the front is my next project. the track is an 80 mile round trip for me, 85mph with the ac blowin cold on I-10 west

You say over drive, is this a stick or auto tranny? If stick good luck on hooking that rascal up on radials at the track Slipping the clutch may work well, or bog it with real low RPM on the line and hope it sticks

It's definitely making power, you've not nice mph. Nothing broke and you and the car made it back home, and it sounds like you had a good time anyway. also like Ron I'm interested to hear the combo.
I have the 555"R" on my b body, but I only use them for street. For strip I've always switched to Hoosier quick time pro/bias/wrinkle wall cheater slicks.

512ci, cold air conditioning, overdrive, mild gearing, sounds great. I like what you did with the air Pan for the scoop, that's a different approach and looks good.
