Default 12.7s?
So I'm thinking with my current modlist and a couple tweaks I can hit 12.7s Tell me if you think it's possible.

What I have:
OEM ramair intake
madz mail tune
LPP headers with open Y
3200 stall
3.42s
17" WS6 rims out back with 275s
16" swirl (93-94 oem rims) with ET streets

What I ran:
13.15@102.69

What I am going to change:
Restall to 4000
fix random misfire
skinnies up front


Think it's possible?

Yep, if you were dead hooking then the 4k stall should really help. I was dead hooking to 1.9's with my 3k stall I need a new converter

I dont see 12.7's with that mph. Hope you do but I would say a 12.9 would about knock it in the head. If you were trapping 106 - 108ish I could see 12.7's

But it's all in the 60. Get it to come out HARD and you could do it.

I'd say NO just changing what you mentioned. 4 tenths is a lot to gain with just a converter change and skinnies. Oh, and despite what people say about the 1.7-1.8 60' times, that doesn't always equate to a 12 sec timeslip.

I also will have to agree that you don't have the power to get 12.7s. You might be able to crack into the 12s no doubt, but 12.7 is a stretch.

Well he said his best 60' was a 1.86, so if he can manage a 1.66 or so I think it would be possible.
