Re: 88 GTA just getting started
One question: Why are the times so high when you have a 406 HSR in it or are those times on a 350? Mine ran 14.25@96 and all I had at the time was a 350 with a SuperRam on it and some bolt ons/upgrades.

Re: 88 GTA just getting started
From what I have seen browsing the forums for the past two years, a stock L98 does mid 14s, low 14s with a good driver.

Re: 88 GTA just getting started
I have read all the magazine articles posted over on the source page and everything I've read says the GTA does high 14's generally from the factory. I can imagine mid 14's, but 14.2 is just pushing it for me on a stock L98 from what I've seen and read. I'm not calling his word into question, I'm just curious on why I'm not faster than that given my mods. I dynoed at 235WHP and 318 WTQ which is about 40-50 HP over what they made from the factory when you factor in the driveline losses, so how the hell am I only running with a stock 88 GTA that had 15 HP less than me from the factory since they were rated at 225 and mines rated at 240?
