LT1 Kill by a Third Gen

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.

i started messing with things, and i eventually realized that:
1. the tach wasnt just off. it was waaaaaaaaaay off.
2. the trans shifted too early... TV cable was correct. but it shifted to early for drag racing.
so by manually shifting it, letting the RPMs go up by ear/feel, and working on the launch... i got it down to 16.001... i had one night of all 16.0s... but i never got that 15sec slip from ennis.
anyway, heres a dyno of my stock 305TBI with no smogpump and no catback (cat still there)

However, even if all the stars aligned and you had -2000 DA I don’t see one of these cars going 7/10th quicker than yours did (stock).
Thanks for the dyno sheet. It looks just like I would expect.
There's a local kid (down the road) that has a 91-92ish 305 Camaro. Im not sure what he all has done to it, but the best I've ever seen it run was a 15.9 on a cold dry good drag racing day

My 86 tpi iroc with a 305 to 350 engine swap, hooker comp headers, comp tpi cam, msd ignition, ram air w/ K&N, ran 14.28 w/ .385 reaction at best. My 95 t/a LT1 ran 14.08, .53 reaction, and pretty darn close 60' time with only exhaust. 305 third gens are good for junk storage.

The best thing about the internet is that you get the opinions of literally everyone.
I also know that on the net getting people to believe what they have bred themselves not to believe in in the first place is like trying to convince me to buy a ford.
So it is all very possible that his car has killed LT1s, I know because I've been there, and for whatever excuses we can make for those cars, you guys will point out. And maybe some are true.
Either way, I wouldn't write it off as being BS. I have setup a dyno appointment for his car, and will post it no matter what the outcome. Then the BS party or the believers will have their proof.

Thanks dude. You guys clearly have something against all third gen's. You guys didn't see the post that my car ran 15.3 bone stock leaving it in drive with it shifting at 4500... If you guys really want to see what if can do... Just private message me if you live near me and i'll show what it can do. I'm not saying I can beat you but i bet it will supprise you. haters

Maybe someone put a 350 in but kept the TBI? Also, what was your mph? People are "hating" because its hard to believe a mildly modded 305 TBI f-body, beat an LT1. Without proof of course. I'm not raising a BS flag just yet, but i would like to see a dyno sheet or time slip before i'm convinced.

and what are the free mods for the 305tbi engine?
Thanks

goto Thirdgen.org..... thats the LS1tech of the thirdgen world.... they'll have tons of cheap TBI mods for you there..
hell, everything they want to do is cheap.
btw, in the end, you'll find that unless you replace everything under that TBI, you're still slow... and once you do replace everything under the TBI, you'll find the TBI itself is holding you back.
its not worth the effort to mod any305 tbi... they get good hwy milage... keep it somewhat stock, and in a few weeks/months/years when you have the money/time/desire.... THEN change it to a decent drivetrain.
until then... just leave it alone..
just my opinion of course.

This isn't a case where two comparible cars lined up. This isn't a case where traction or driver error is an issue (at least not according to him). When a car that traps around 90 claims to beat a car that traps around 100 from a roll then you're going to get disbelievers and rightfully so. He even states the LT1 was modded with exhaust work. A bolt-on TBI beating a bolt-on LT1? Sounds too good to be true so it probably is.

I do appreciate the intelligent break down of my post, and was only giving my side of it.
While I am bias toward the car having ridden in it for the past 2 years for A LOT of races I am not about to think that my beliefs should be instantly recognized as disproving the cold hard facts of what each cars known for.
So until the dyno day, any further talk on my part is just more speculation. I am all for just getting that thing some true data.
So far ls1tech has proven to be a lot more friendly than thirdgen.org where the only thing you can expect is great tech data and a lot of

im an a$$hole over there. why? because i almost need to be.
do you feel like you're being picked on by a$$holes over there? if so, you're probly talking over your head, speculating, or posting other things that dont belong.
look at that dyno chart i posted.
thats basiclly what his will look like, except move the lines up 5 to 10hp.
all that torque down low, it wont feel TOO slow to someone new to cars.
to anyone whos actually into them for a number of years, you'll either know its slow, and not be fooled by the TQ down low.... or you'll know its not a mostly stock TBI 305.. take your pick... because no matter what, it is impossible for a stock internal TBI to make that much power.

I have never posted on thirdgen.org
The tech data is great, used it for my two thirdgens daily.
I know lots of people who feel the need to be ********, so you're not alone.
Oh, and I'm not too new to cars. My family owns and sells streets rod and American Muscle. And my big block feels kind of torquey.
I won't argue over anything till dyno numbers, your friendly input was awesome
