HP and ET estimations are useless without solid numbers to base them on. And it can't be based on This car vs That car arguments.

There are formula's that can estimate your trap speeds, but they require accurate Engine HP and accurate Race Weight data. They also are estimations because they are based on "line of best fit" formulas generated from hundreds of observed data sets.

You can't prove your car can run the #s you say it runs. If you truly were a secretive street racer you certainly wouldn't have made this thread because you would want to keep ANY knowledge of your car off the net. I'm going to go with "you think your car is faster than it really is" mentality.

If you wonder why the TGO community is so skeptical its because we've seen hundreds of threads like yours over the years and vary rarely have the original posters been proven right once they actually hit a drag strip.

Dont always need a faster car to win the race..not sure what all the fuss is. Maybe the car isnt as fast as the cars he is beating but thats not the cars fault..its driver mods.

My 99 ls1 auto TA has waxed a new C6 Z06, new SS 5th gens, and only lost by a carlength to a GT500 stang. Beat a 3v GT stang running a 100 shot. All these cars should have beat me but I was able to get off the line due to drag radials My lower 12 sec car vs cars that should run alot faster that me, especially the Z06 and GT500. The GT500 got me because I spun alittle.

I have to agree with what Orr said. One second differences in ET between two opposing cars isn't that large of a margin at the track, as when it comes to 13 and 14 second cars running each other on the street, or on the track, it comes down to reaction time and proper shifting. Don't think a 13 second car is going to put bus lengths on a 14 second car. I myself look at things differently though, as if I race someone at the track and win, yet I see that their trap was faster than mine, then I immediately feel that I lost, despite winning, because the potential of the other car is greater. But by that logic why even race at all. In the end, whoever wins, wins. Coulda, shoulda, woulda does not apply in racing. Whoever wins, wins...

While I'm doubting the OP's claim of being as fast as he is (he said he can spin at 30-40), this is true. My car for example is probably making somewhere around 430 hp or so. The only time I took it out to the track, my best time was a 14.9 Embarasing I know, but I was still spinning at the 1/8 mile mark. Doesnt matter though. That night, my car was only a high 14 second car.

You guys are right. I built mostly ford engines 4cyl and northstars in skool a few Honda motors mostly H22/H23/F22B1 I help in some sbc 350 builds no real big hp engines just mild and O.E. I seen big Hp engines build but I did not help I know what goes in them I know how they work and a sbc engines are ez to build if u had all the parts tools in hand I would think it would take a few hours to build it. That's what it took me and my friend to build his 350 and drop it in.
I don't think my car is fast lots of torque yeah. I love racing so I raced a few cars on the street and that was the out come. I didn't post this to start anything as y'all ca see I new to the site anddid not read or see any post like mine but I do hear ppl on the streets like the guy I raced in the stock 93 lt1 saying he keeped up with a new Z06 he can't keep up with me and I can't even go to the same gas station with 1 and he said he beat a new CS stang, I no longer hang with that kid all he do is lie about bull like I care I raced a new GT and on a roll and he pulled on me. Like I said be4 I get talked down on about my 305 and 305s alike I never put money on my car real money anyway but like a fight I won't back down from a race and this was the out come the cars that I said I beat was all the cars that I knew I was gonna get killed I can tell y'all bout all the other cars but y'all wouldn't care like the new GP GXP but my friend new SS impala gave me a run for my money at top in a 1/2 mile from 0 he was comming but was out of road but he would have pass me. The GXP did have a chance so I do say driver is most of there's cars down fall I got my but kicked buy a LT1 with 4.11 or 3.73 gotta ask him with 20s so I would say driver but I never lost to any hemi but I'm sure they would get me on the freeway. I don't do freeway racing TPI is not made 4 that 4500rpms and ur done.

I have drove a new SRT8 Challenger stomped it it was a auto was slow to me it didn't pull hard but the R/T Charger and 300C kicks in the low end to me when I drive them they feel like they should beat me the worse 1 was when my friend hopped in a 04 ZO6 and lost he didn't know how to shift was shifting at 4000 lol so I don't and will not count that as a win

WHY WHY WHY did I waste money on a vortec 355 when I could have done a LB9 swap STUPID STUPID STUPID

Thirdgen89GTA

iTrader: (5)

The proof is in the pudding. I run dead even with R/Ts. They may have 350hp but they are heavy. However the R/T still trapped 1-2mph faster EVERYTIME we raced even though I'd beat him to the finish because i could drive better and launch harder. Sometimes were were amost door to door across the line.

An SRT-8 would walk away from me everytime unless they completely blew the start.

Idk why u waste money on a 355 shoulda did a 383 if your set up not right that a well put 2gether 305 would be getter what trans u run a 350 or 400 I run a 700R4 with 3.27 gears and vortec heads aren't money they are like 100 bucks what cam u running 1 from a truck. Don't hate on me I'm saying drive mod on those cars I ran 4 hemi's all chargers. Can I be the better driver or that 1 out of a million 305s that beat some bad drivers the thing is what I read R/T chargers run low 14s that was on C&D that's with good drivers and new cars a stock lb9 with 2.73 gears and a auto runs low 15s high 14s and mine not stock so its very possible. Y'all need to stop hating on the LB9 what it can't beat your kid powerwheel nexts yer gonna that. Yeah its a weak motor but so was the 350 a 396 can do better numbers but a 350 built right can hang .

big hammer

i hope for your sake that you're just trollin'

midias

Wow excessively hard to read but let me see if I figured out what you were asking. Or maybe just stating which was it?


I run a T5 with 3.73 gears
The block is 4 bolt main 350 bored 30 over.
The vortec heads are punched out for 2.02 and 1.6 valves, 5 angle valve job and blended bowls. They are machined for screw in studs, guide plates and higher lift. They have 185cc runner and 64cc chambers giving me about a 10:1 compression.

The cam is a comp cams XE274 cam with about .490 lift using comp 1.5 roller rockers.

Nothing crazy on my setup but more than enough for me to "drive mod" around here.

Still very confused about the kid powerwheel comment and well most of the other stuff I tried to read but it does not matter. I did my best to answer what might have been questions and that is all that should matter.

On his 355 yeah just kidding but that's what they ran low 14s but I will look it up again last time I looked it up was the night I raced the 2 chargers R/T

Orr89RocZ

iTrader: (20)

some of those hemi chargers are not that fast. I've been in the AWD versions and they are pigs...low 14's...thats well within the reach of a bolt on well driven T5 305 car or a mild L98.

Challengers I've no clue..the r/t base hemis likely high 13's with srt's being low low 13's capable of 12's with little mods. Last one I ran trapped 110mph, same as my bolt on Ls1 car

I love these threads and regularly troll them. The fun is great .

The 305 debate has definitely gone from the sublime to the ridiculous.
All my cars are 305's and I would never contemplate taking on anything.

The next aspect however is that you can post numbers and the debate then goes on as to which dyno did you use and was your time slip done at altitude or sea level.........

The HEMI engine is a BEAST though. My little 5.7 that is internally stock save for a mild little 212/212* @ .050 cam, 6.1 pushrods and springs is running 13.40s @ 99 in the 1/4 on drag radials in a 5,200 lbs race weight Ram. On the street tires it runs 13.50s @ 98. To put it into perspective, both of those cars were 12 second cars @ 106-108 MPH.

Don't dog on the Hemi with a few mods it will KILL most Thirdgen cars.

I saw a 2012 6.4 Challenger run 7.70s with nothing but a cat-back exhaust, intake, and sticky tires. He later went out an hit 11s in the 1/4.

iTrader: (8)

WTF is going on here? Seriously, just WTF is this? This thread is full of so much fail it's not even funny.

First off, I caught something about you beating an 04 Z06 because the kid was shifting at 4K rpm. If I was driving that Z06, I would beat your 305 shifting at 3k rpm. Those are low 12 second cars stock, and you wouldn't have a prayer against one.

Second, ok, the LT1 win is semi believable because 93 was a crap year, and those cars were not the quickest stock. But a couple challenger R/T's? C'mon man, you need to step into reality. They run high 13's stock but trap 105 ish because they don't get off the line quick. Thats moving.

Third, saying your a good driver as your reasoning for winning is just retarded because your car is an automatic and doesn't have enough ***** to spin the tires off the line. I wouldn't call that being a "good driver." More like your good at stomping the pedal and lying.

Fourth....LEARN TO TYPE DUDE!! I have a damn migraine now after trying to comprehend what you have been saying through these painful 3 pages. Use a few periods once in a while. It's not that hard!

Oh, and...

bobbyk3lly

hahaha guys, hes not bullshitting you,

ive went thru 3 cars trying to beat his 305,

i had my 94 lt1 auto shooting flames out of the tail pipe trying to beat him,
then after blowing up my motor in that racing him,

i bought an 83 z28, built 355, headers, cam, rockers, the works, STILL couldnt beat him,

then i bought a 93 z28 6 speed (one in the video)

I DID NOT LET OFF! he caught up, and yes he did beat me,
BUT! i had a hidden oil leak from my passenger valve cover at the back of the block
leaking down into my trans, causing my clutch to slip, i replaced my clutch with a summit racing one, and when summer time rolls around you WILL see a rematch video,

and with the work were currently doing to his car, id like to see what happens,

and as far as running these cars with him, he has videos to prove this, and i wouldnt doubt him, ive been with him when he was running most of those cars,

and he beat their ***'s without even a struggle, ive driven his car, its the fastest auto car ive driven, it by no means is 100% stock,

bobbyk3lly

like i said, ive personally driven his car, its pretty quick,

and to me it sounds like the guy you quoted has some "personal" "size" issues with himself, and i would LOVE to see him line up against his car, believe me, you would walk away with your foot in your mouth,

ill have to post up pics of the cars of MINE that he has beat,

bobbyk3lly

wow are you kidding me??? ive beat rt chargers and challengers in my 83 z28 when it was running like total SH*T! those hemis are not only slow, its the weight of the car that really screws them over,

i could beat a rt in a 305 tbi car, and infact my buddy tony harris HAS in his 89 rs 305 tbi car, by half a car! they are slow and heavy,

see this is honestly one of the reasons why i went with a 4th gen, because most of the guys on TGO are cocky and can not seem to get
over their "size issues" long enough to talk with someone like a normal human being, instead of being a ***** to someone without personally knowing him or his car....

so have fun, and go take your extense

whitedevilTA

iTrader: (8)

You are just as dumb as the OP if you think you could beat a challenger RT in a 305 TBI car. You two go have fun praising your buddies 305. If he beat you when you had a "built" 355 then you had one sorry 355. I am not saying the 305 TPI is a completely garbage motor. They do have some potential, but due to the bore size and lack of aftermarket support for heads, you can get MAYBE around 300 RWHP out of one N/A. I doubt the OP's is even close to that though with that stock idle. There is a large amount of failure on TGO lately.

I'm not trying to shoot you down real bad...but just understand this. You came on saying how great the LB9 is. Yet you don't even know what you have under your hood since the previous owner built it. For all you know, it could be a swapped in 350 with mods. You have absolutely no clue what you have under your hood and until you find out the details, you really don't have any bragging rights. Look at the back of the block. It should say 5.0 or 5.7, or have a casting number, or SOMETHING to help you figure out what it is.

You seem like a decently level headed guy and I'm glad you have goals and are into your car as much as you are. Just understand that there are guys on this forum that have WAY more engine building experience than you, and we know that no 305 TPI basically stock is going to beat all the cars you claim to have beaten. So like I said, do some research and dig into that thing a bit and then you will know for sure what your setup is. Post back up when you have a chance to take it to the track. Then you'll have some bragging rights.

I agree. Look behind the driver's side head with a flashlight and you should have a 5.0L or 5.7L stamped there. I'm guessing you have a 350 with aftermarket heads/cam. That is the only way you are beating those cars. A 305 just doesn't have the torque or hp to do what you are saying. Congrats on your car tho.

this is the best thread ever. i love it. i remeber selling my 88 iroc to buy my 6 speed lt1 car. the lt1 car was bone stock with bald tires, and the 88 hada brand new trans, stock as well. i could barely drive stick, and raced the kid i sold the iroc to. i must have put 6 cars on him by the time i let off. if only i would have know to keep the iroc and put headers on it.....

I hear u it might be he said its a 305 and I can't see behind the valve cover but I hope it is a 350 kinda I do have the valve covers off and the base its has hyd flat top lifters I thought it would have hyd rollers I wish I can track it with old set up but that's not happin. I was not saying LB9 are great all I said I won a race in a car that I was told it was a 305. This year I will track it and record my street races.

For all of you doubting the 305. My original motor a 305 TBI with ported & polished SWIRL PORT garbage heads, 3" exhaust, headers, custom fog light intake( pro **** ), ignition box, new tune, 700r4 transmission, and the best of the best weight reduction( all i had was 1 seat, a steering wheel and shifter, drilled rotors etc..). With this in my 88 trans am, I beat numerous turbo civics/integras/rice cans, charger r/t's all day theyre slow as ***** (NOTICE r/t NOT SRT), 2000-2004 cobras, any other stock 305 tbi, 90+ ss's, anything under 330 range HP, i simply trashed. and I probably had 250? I even **** on most turbo diesel chipped trucks, and they get fast, believe me. 305 is a good capable motor with the RIGHT mods.

In the rain with my 350sbc, i will spin tires up to 60...

Slayerx666

No way you beat any 03-04 cobras. I don't care if the cobra had 4 flats. No n/a 305 will touch it. My buddy's cobra used to put cars lengths on my lt1 car.

thebuffalo

Your lt1 was slow, And as far as the 03-04.. they had like 320 stock? slow... And I never raced a supercharged one.

my buddies 138i twin turbo with 455 rwhp on a car that weighs 32xx lbs puts car lengths on z06 vettes with mods also destroyed a 600hp gutted trailblazer SS.

EDIT: 03-04 has 385 stock(still slow, especially for v8 supercharged...) running mid to high 12's. Must not have raced that year, so I stand corrected. I beat a 2000-2002's

And I bet a N/A 305 bored and blueprinted with good heads and a good cam, headers, new intake and switched carb will beat a supercharged cobra.

Terminators have a very distinctive exhaust note. They look slightly different but there is no missing that supercharger whine.

Like I said, never raced a supercharged one. Even so, the cobras arent that much faster from the GT, only like 50hp which still puts them above EVERY 305 stock.

Clearly then you've never rAced an 03-04, because they're the super charged ones. Don't call my cars slow till you get your facts straight.

Clearly, I stated this. Your car may not be slow, But it IS slower than 385 hp.


Dont say a N/A 305 wont touch a cobra until you have your facts straight

I love gm, but I give credit where it's due. I'm
Pretty sure my lt1 could beat a gutted 305. All it had was a good clutch, drag radials, long tubes, 355 lt1, 4.11s, k&n intake, and not much else. My buddy's cobra had a pulley and a cat back and cai. Dynoed almost 500hp. It's amazing what those cars make with minimal mods. Forged bottom ends are a nice touch if I'm
Not Mistaken. What is the most someone could get out of a naturally aspirated 305? Realistically? 250-320 to the ground?

As for spinning one tire? My 5200lb gmc k1500 will spin one 36" tire whenever I stomp the gas.... Not that impressive. My girlfriends stock 91rs will do it, and so will my buddy's 305 carbed 80s cutlass....

thebuffalo

I will agree with you, cobras are easy to make more power. smaller pulley, new clutch, and a 4.10 rear end and they will get places.
Top I could see a N/a 305 is 400 to the wheel. But I'm pretty sure the 3rd gen f-body weighs a good bit less than the 03-04 mustang
For the spinning tire, I was just stating to that guy that any thirdgen will spin tires, slow or not.


For you talking about failure so much, you spread a lot of it. No aftermarket support for heads on a 305 is the stupidest thing I have ever read in my life. I am almost 100% sure that ANY pair of heads you can put on a 350 you can DIRECTLY bolt on to a 305 also. Meaning that the 305 has possibly the largest aftermarket selection of heads. It's like you say something smart, then follow-up with something abnormally wrong.

Ignorance must be bliss.

99-04 Mustang GT = 260hp

The Terminators being supercharged at a pulley and tune away from a decent boost in power.

A Terminator which is what most people talk about when they think "SVT Cobra" is is MUCH faster than the GT of the same year.

Are you ignorant, I'm fairly sure I stated the 03-04 horsepower already?
