quarter mile times, 305TPI no A/C, no smog pump.
Alrughty, i have a 305TPI trans am. My car has full interior, no AC, no Smog pump and runs on 91.
yes it is an automatic, with stock gears.
I do have fourth Gen LT1 injectors.
street tires 235-60-16
I'm curious what could it run in a quarter mile?
I will be running it this Friday at thunder valley, in noble Oklahoma. I will have feedback to return to all the responders.
maybe even a video

Re: quarter mile times, 305TPI no A/C, no smog pump.
So, how did you do?
I have an '87 LB9 (305tpi) with a 5 speed and 3.08 gears (that the PO put a lightweight clutch/flywheel assembly in it making it impossible to launch well), the engine is stock TB to y-pipe that I've run a best of 14.01@99 with a 2.53 60'. With a stock clutch or auto it would run well into the 13's...

Re: quarter mile times, 305TPI no A/C, no smog pump.
I have a 91 auto stock but with a tune i am looking to dyno and baseline at track, but i can say its one of the slowest cars i ever driven lol certainly dont feel L98 fast which is mid low 14's.
My 6.2 full size ext cab feels faster by far and its a low 14 maybe 13 truck i'm told from others with similar configurations
