The first street night at new england drag way is coming up in a few weeks and my car isn't registered right now. So the only thing i'll have to race is my reg. cab short bed 5.3 silverado. A buddy of mine might be bringing his 89 tpi 350 iroc. Completely stock minus k&n filters and some ram air ducts he had some guy make for him. I have a CAI, exhaust, electric fans, and a set of msd superconductors. my truck stock is rated at 295 horse and 335 ft. lbs. torque with a locking 3.42 rear, i was told my truck is in the weight range of 4800-5000. He has the 2.77 rear end in his, i think its posi. Simple question, him or me?

Jgolden314

If his car is in good tune, I think he MIGHT win. Your truck prolly isnt a slouch by any means though. Those 5.3s can be fast as hell with a few mods. I think you will be right behind him.

are u serious? a 5.3 truck is not a mid 14's truck....

i have killed all kinds of trucks.. ram's f150's, silverados... etc etc. the Iroc will kill the truck

Jgolden314

I have never seen a close to stock 5.3 run so I did not know. My friends STOCK 4.8 silverado ran 15.2, so who knows.

90Formula305

F150=big ugly and slow, ram=pwn'ed hemis with mine. ive got a friend with a 4.8 and 5 speed that ran 14.98 with a flowmaster muffler and a K&N filter. The 4.8 has significantly less torque than a 5.3. So take it easy, for a truck dude mine hauls ***. I guess all i can do is see.

Jgolden314

Hell yeah I love SWB 5.3 silverados.

slap a radix on that bad boy and listen to the whine!

90Formula305

I was thinking cam, stage 2 5.3 heads from afr and a procharger.

Jgolden314

That would work. SLP makes some nice head and cam packages for them as well. I plan on picking one up in a few years, and doing mild mods to it. What color did ya get?

5.3s aren't bad mills, but i think you'll lose by a few tenths

90Formula305

Silver birch metallic, it was the last 05 they had.

ShiftyCapone

iTrader: (7)

You will lose.

90Formula305

what do tpi 350's run stock?

ShiftyCapone

iTrader: (7)

13.9 to 14.5 depending on the year and driver.

90Formula305

oh well, be fun to run anyways.

ShiftyCapone

iTrader: (7)

Yes it will and anything can happen when racing. You never know. The car that "should" win doesn't always cross the line first.

89IrocZ350TPI

Id say 87-89 models are in the 14.5-14.8 range, and 90-92 sd cars are in the 14.2-14.4 range.

btw- Have you ever seen a stock L98 run a 13.9? Seems far fetched to me beacuse thats what the stock LT1's run around here.

Orr89RocZ

iTrader: (20)

under the right conditions, it could be possible for a stock L98 to go 13.9. trap speed is there on some models. with solid tires like drag radials i definately can see one go that fast.

i raced a blown silverado SS at the track. he got a 1.80 60 foot to my spinning 2.07 LOL and his reaction time killed me too so naturally he jumped way out in front of me. he ran 13.19 but only at 101mph. i trap about 100 on good conditions. he ran a 8.34 1/8 at 81mph. where i usually go about 8.8 at 80mph. after his initial 4-5 car lead, he never pulled much after that.

from the right roll speed, i would hang well. he just murdered me off the line with gearing and low end power. this truck was supercharged. a stock or nearly stock 5.3 n/a wouldnt hang anywear near as well. but again, i got full ehxaust and 2800 stall. most L98's now have exhaust mods like mine. in good condtion they should go high 90's mph in the traps. which should be more than those chevy trucks

thats just my experience with these trucks. my neighbor has a 5.3, my dads friend had silverados all his life, my best friends dad had a 4.8 one and now a 5.3 one. i never driven it but been in it many times... they are quick down low but after that its allll L98 Irocz

89IrocZ350TPI

I guess so, driver and conditions are a huge factor. My track opens up April 1st. I got some slicks this time, and i cant wait to see what numbers i can get.

90Formula305

The 5.3 peaks out around 5200, mines got alot of nut up high, it pegs 100 like nothing......then stops dead cause it doesnt want me to go any faster.

87TPI350KID

Always root for the underdog. Truck will win.

89IrocZ350TPI

What if the underdog was a riced out accord

90Formula305

ummmmm.......heh heh heh heh....He's going to take his 97 Z28 now. ****. It's bone stock though. damn it.

89IrocZ350TPI

He should be in the 13.8-14.1 range and trap 100-102. I say you get smoked......Sorry lol

urbanhunter44

iTrader: (3)

DRs aren't stock though.

I don't think it's possible for a stock L98 fbody to hit a 13.9. With tires - yes.

Orr89RocZ

iTrader: (20)

eh its all in your definition of stock... i guess tires isnt stock... but you cant run the stock tires that actually came from the factory with forever you know. so if you do buy drag radials, thats street legal and just a tire. so yes and no, its stock and its not stock all at the same time... power wise and gear wise, stock no mods with tires only it would be interestin to see how she moves

RED5SPDFORM

well silverados are no dogs by any sort, my dad has an 04 extnd cab with the 5.3 with an intake it hauls *** for a truck. I you want to get close to that IROC, Id go with a powerprogramer, exhaust, and an intake and take it from there. check out this site for some info about some fast silverados http://www.performancetrucks.net/forums/

IROCThe5.7L

My buddys 1991 B4C ran a 13.9 stock. Paper filters too. No slicks or drag radials.

urbanhunter44

iTrader: (3)

i'd need to see slips or a vid to believe it. What was his trap? What was his 60? What was the 1/8th mile et/trap?

Ive heard alot of fish storys of 13 second stock L98s, but have NEVER seen proof. If someone can prove me wrong, I'd love to be wrong because that would be awesome.. but I doubt anyone has proof.

not saying I don't believe you, just saying I want some proof

89IrocZ350TPI

I agree. The BEST i have EVER seen was a 92 L98. He ran 14.3 at 98. I want to see some slips!

90Formula305

Naw, im gonna get a custom tune. Much better than a handheld and a hell of alot cheaper. Going to have it retuned to run 89 and 50% of the torque management taken out.

ShiftyCapone

iTrader: (7)

Your car doesn't have torque management. That is only seen on the new LS2 vettes. Custom chips are the way to go but unless you have any mods GM already did the legwork for you. You won't see any gains by changing timing to run 89 octane.

urbanhunter44

iTrader: (3)

yeah I don't think traction control was even an option in thirdgen years. My '97 has it, however I don't know when it became an option, had to have been 93+

ShiftyCapone

iTrader: (7)

'95 was the first year ARS was available. It was never available for any 3rd gen.

Torque management is actually different though. When you go WOT it backs timing and fuel the last 100 or so RPM before you shift. This greatly reduces driveline shock in efforts to maximize half shaft life. GM encourages its C6 owners to take their car to the track. Because they do this they had to prevent warranty issues with this feature. With it removed a stock C6 will reduce it's ET by over a half second (IIRC).

Orr89RocZ

iTrader: (20)

good point shifty.. maybe thats why the C6 i raced only ran 13.88 at 105.. ofcourse he had a 2.3 60 foot

urbanhunter44

iTrader: (3)

Ah I see. Thanks for explaining that, I hadn't heard of torque management. How exactly does GM encourage C6 buyers to go to the track? Hand them a brochure or something? lol

ShiftyCapone

iTrader: (7)

This I am not sure and what I have been told has been though magazines and word of mouth. GMHTP mag could only muster a 13.0 with a stock C6 and by the time they were able yo hack into the TM system they could run a 12.2. That is a HUGE difference with no mods added.

87TPI350KID

If the 5.3 pulls anything like the old vortec 350 did, it should haul.

indirocz28

The only trucks ive ever been beaten by were a 400 hp ford lightening and a dodge Ram RT V10, and a very beefed up Dodge Cummins...

And i was in a 4 cyl automatic Eagle talon.. the chevy ss 496 didnt even stand a chance.... neither did the 88 chevy SS..

but as far as the 5.3- i think the IROC would take it..

urbanhunter44

iTrader: (3)

Yeah 400 hp should be good for bottom 12s, 13.0s cracks me up

90Formula305

www.gmfullsize.com tell these guys that the 99 and up trucks dont have torque management. Everyone on there runs a custom tune to run either a more aggresive tune for 87 or advance the timing to run 89 or higher. They also have torque managment taken out. Trust me on this one, it has it and i know what it feels like when it's in operation.

Edit: Did you think i have traction control? The torque management in the trucks retards the timing between shifts so it doesnt have as much power shifting into another gear to extend the life of the tranny. Thats what i meant.

Edit again: and i just noticed someone else already explained it....

urbanhunter44

iTrader: (3)

oh I thought you were talking about your Firebird!

90Formula305

Oh no, i think fuel injection is the most technologically advanced equipment on my firebird. Not like its going to saty that way though.

urbanhunter44

iTrader: (3)

Yeah thirds never really had much in the way of technology so to speak, except for fully optioned GTAs.

The really neat stuff came in '95 (maybe '96) with the introduction of the BCM Automatic headlights, daytime running lights, factory alarm, retained accessory power (actually in 94s as well), inside lights that dim out slowly (oooohhh)! Wonder how much work it would be to put all of that crap in a thirdgen?

I know retained accessory power isn't hard to wire in a thirdgen, someone on fbody.com did it.

banditfirebird

the camaro should win. My LO3 firebird is stock besides a msd coil blaster and it will outrun my brother in laws 99 f-150. not smoke it, but a good car length or so. I rember him telling me about him racing a newer silverado and beating it so him running the 350 tpi he should smoke you. But who cares, its a truck right? there not made for speed so there is nothing to get mad about if you loose.

89IrocZ350TPI

Id be mad if i lost to something that wasnt even made to go fast lol.

Is it just me or is everybody else getting sick of the "corvette with a bed" chevy trucks. I cant even drive my car without a full size chevy truck trying to race me. Every freakin day. Ive never been beat by one neither. Its always the same excuse when they get beat too. Its just a truck. If its just a truck how come your racing in it. Its run what you got, no excuses. I guess "Its just a truck" is how they sleep at night. I guess that makes it like a poker game, going all in with a bag of dirt against their $50,000. If you lose you think its alright to not care cause you dont think you lost anything. I'm really not trying to **** anybody off. This is just my opinion of those trucks. I guess all the mustangs around here traded them in for chevy trucks so they can lose with their dignity. I personally know 3 people who traded mustangs for these trucks.

Also, GM should have them come with duel exhaust as an option also, they'd make millions, cause 90% of them ive seen have it. Enough of my rant.

80smetalfan

I think the 5.3s are pretty freakin awesome. I don't really get the comment about only pulling to 5200 that was made by someone else. The one in my parent's Suburban seems to pull pretty well to 6000. Seems very similar to an LT1. I would LOVE to get one and a T-56 and put it in either my G-body or an F-body. I think it could be pretty fast. As cheap as you can find em at SOME salvage yards, I'm surprised I don't see more people swapping them.

However, why they were chosen for a truck absolutely confounds me. Maybe it's the Stabilitrak in my parent's Suburban, but it doesn't seem to have any low end punch to it whatsoever, compared to a Vortec 350.

urbanhunter44

iTrader: (3)

why swap a 5.3 when you can swap a 5.7 for the same cost? Or screw that, get an LQ9 my moms vortec 350 burban is actually pretty quick lol im sure it's in the 15s somewhere, i'd love to take it to the track.

What annoys the **** out of me is EVERYONE taking their trucks and SUVs and putting damn flowmasters on them

80smetalfan

Gen III > Gen I

Unless the 5.7 you're talking about an LS1.

I think as common as the 5.3 is, I think it will probably become the next 350 in terms of popular swap. There are only so many LS1s out there, and there are bazillions of 5.3 equipped GMT-700s, not to mention the new Monte Carlo SS/Impala SS and Gran Prix GXP cars. MUCH more common than the 4.8 and 6.0, it will be much cheaper at the JY.

Jgolden314

Hmm, let me see

Ever see a modded diesel run? Full size, and some are in the 11s, and drive it home.

Also, You need to make a trip to michigan, I know of a handful of full size trucks that will put lengths on ya lol.

This is the future, whether you like it or not. Suvs, and trucks are getting fast. Look at the SRT8 Jeep....425 hp with AWD.

And No im not mad.
