I'm going to guess a 15.45 @ 89.76mph.

When I had the LG4 in my 86 Trans Am, first run ever at a track was a 15.20 at 91mph.
6th run was a 14.943 @ 91.67mph


Only mods I had were an Edelbrock Carb and Intake. Stock manifolds, stock exhaust, etc....

 

i dont know what youd run but youd probably have a better time if you got in the car and drove the thing....oh i crack my self up....yeah the general consensus is that the 5.0's will run mid to high 15's although these motors are getting older so low 16's wouldnt be a surprise.

 

mid-high 15's, friend south from me ran 15.3 with a mod or two

 

Nah, a 5spd non-G92 should still be able to get low/mid 15s at worst driven well/in good tune... Seen/heard of a few of the 91-92 autos hitting that stockish, no way does the 5spd model with 3.08s run as bad as high 15s launched well IMO...

 

From what i have gathered I will Run about 15.2 - 15.5,
is that about right?
I am going to the strip soon and i want an idea of what i will be running...

If your car is a 92 then it has more like 230hp/300ft lbs tq.

 

Very true, it is very hard to guess like said above.. When my 1988 IROC was stock (195hp) i ran a 15.02 @ 92mph (2.01 60'), i think thats considered pretty quick for a stock 305, could have something to do with the driver though LoL

However the same night i pulled those numbers ther was an 89 formula with a 305, 5spd, shorties, catback, slp runners, chip, boltons running 15.9-16.2s, maybe his motor was tired or something i have no clue but he insisted that i must of had a 350 and didn't know it lol..

 

I think it was more a case of his 305 5-speed Formula was shot!! I mean, just look at GMHTP buildup and you can see what a 305 5-speed can do with those bolt ons.

 

The non-dual cat/3.08 geared 91-92 5spd TPIs were rated at 205 hp like he listed, the dual cat/3.42s were rated at 230hp. Most of the difference is supposedly because they got the smaller cam that was also put in the autos vs the one the dual cat/G92 5spds got.

There is however some evidence that all the 5spd TPI cars did indeed get the hotter cam, in which case the 205hp rating is definitely underrated by 15ish hp... (evidence being a couple people online have claimed to have pulled them out, and spec'd them out to be the larger cam...)

 

That is very interesting....

 

i ran my 87 5.0 tpi at english town with just an exhaust and pulleys and of course the free mods and got a 15.6 but i shifted out of 4th at 6500 mistakeeeeeeee i could garantee i could hit 15.4 on another run but yes mid 15,s but mine was in pretty good condition well taken care of before i got it . your launch will be impressive tpi cars get up a moveeeeee baby torque your head off

 

i meant shifted out of 3rd sorry
