I will call BS. I have never heard the words/numbers "factory freak" and "305" in the same sentence. Like saying 115lbs heavyweight champion. 10 years ago my buddy had a low mileage 305 tbi RS 5 speed and i could beat him driving my moms 96 grand am GT. He had cat back exhaust. Maybe you raced a poser T/A with a loud piped v6.
I dont think his story is b.s., I just think his car has more than he knows. Look at all the posts of people that have previously owned these cars compared to his. Even his friend said the one he had was p.o.s. I think it has some more work done by the previous owner or something.

I know this won't count for much more, but I have sat shotgun for half of all races this guy has done, and am no stranger to faster cars. While this thing isn't amazing, it isn't a killer of ALL LT1's, it is by far the most impressive quasi stock thirdgen I have ridden in, and I've owned 2 myself.
Me and 305 302 eater have tried to go over anything on the car that doesn't fit the 305 the VIN says should be in there. The motor when he got it was the picture perfect example of a 305 paper weight stock motor. I know my cars being a dealer and this thing had the old man/lady pride of ownership written all over it.
His track time was very impressive for what the car is, so suppose with all these mods he maybe just increased power by what, maybe 25hp to the ground? If he was in the high 14s, wouldnt that put him in the range of some, not all, Lt1s. And technically, not to sound like I own a civic, but he does weigh some what less. My info puts him at 3290 before driver.
Another Point in case, my 87 GTA with an original 89,000 Miles TPI 350, shift kit, 3 inch cat back could not pull on him. And I can drive well enough.We were dead even. All GTAs in that year with similar mods hit 14.5s from what I know, isn't that stockish lt1 territory?
Sorry for the long post.

Of course that doesn't mean a poorly driven lt1 that is in bad shape wouldn't be slower

Thanks for the help dude... my car ran with the gta my friend is talking about with my 700r4 and 2.73 open dif. and not even half the mods i've done now. About 6 months after that i raced a white gta same year same suff done to it as the other gta and i had put a shift kit in mine and underdrives and thats it. I BLEW his doors off by 50 had a good car and a half. he shut down. I don't think my car can beat every lt1 on the road. I don't think my car is fast, but for what it's supose to be its very respectfull. I will try and get numbers posted as soon as i can. Again, thanks to everyone who believes this, and thanks to everone else for not ripping me up.

So let's do the math here, most stock LT1's trap about 98+/- mph, so 305 302 eater is picking up 10 mph from bolt on's? Come on now. It takes about a 100 shot N2O to pick up 10-15 mph in the 1/4, so shall we say the bolt on's on this RS netted it 75-100HP?
were i race no where near sealevel lt1 cars run high14s low 15s stock.my ls1 ran low 14s stock just like all the others do.the way a car is setup really helps in a race.da and sea level play a pretty good role as well.what are youre bolt ons

I have full length hedmen headers to glass pack dumps, smog delete, AC delete, 22% underdrives, TBI spacer, injector spacer, dual snokle intake, 180 thermo, K&N airfilter if you want to count it, iridiom spark plugs, msd blaster coil. tbi chip. Basicly anything you can do to it with out touching any internal parts. That all really changed my car completely.

its not putting out 70 more hp because its a freak.
its putting out 230 MORE hp because it has a cammed LS1 in it. (stock hp was dynoed at 152. stock LS1 was 316. cammed with manifolds was 360-something. cammed with headers is 385.)
also, the car used to weigh 3615.. now it weighs 3000.

the TBI sucks.
the the intake sucks
the heads suck
the shortblock sucks ( tiny *** bore. low compression. weak rods. ect.)
the cam is litterally the smallest roller cam GM ever made for a v8.
your mods.. well..
full length hedmen headers to glass pack dumps - this is a performance part.
smog delete, AC delete, 22% underdrives, TBI spacer, injector spacer, dual snokle intake, 180 thermo, K&N airfilter if you want to count it, iridiom spark plugs, msd blaster coil. tbi chip. -- this is all crap that you have wasted your money on.
if you truly want me to tear it apart piece by piece, i can explain to you the why on each one.... if i was really bored, id go in Thirdgen.org (where you belong anyway) and provide links to each point.

w/ headers & 3.73's couldnt come close to an LT1. Ive even raced a 3rd gen with the SAME set up, dude it wasnt a race at all..not an ordinary 305 lol they all suck bottom line. my old 85' had a frankenstein 305 in it from a truck and the TPI was from an '88z with some of the same bolt on's like the u/d pullies & dual snorkle w/ k&n's, 3.73's and it had an exh cut out but the thing that gave me the most power was the cam (204/214, .423"/.446" LSA110). and like i said i was never too far behind my buddies L98, it was always ended up between a fender and 2 lengths when we raced.....

But I understand wanting proof and believe in my car enough to post when I get it. I can say that with the mods I have done, the car has changed completely, it is not a common third gen slug that everyone thinks it is.

The car was a complete turd. It ran a best time of 16.1x @ around 90 mph.
There is no way you will ever convince me that a 3300-3400 pound (+ driver) 170hp car with an automatic transmission and a 2.73 open rear will run 15.3. Not to say that you didn’t, but you’d need a lot more power to do it.
I would be very interested to see what this car dynos.
