Anyone ever raced one or know what they can do at the track? A kid at my school has one and says he beats corvettes . With 255hp and like 400 lb ft. they can be fast I know, but they have to be a total b!tch to launch. If I raced him would I have a chance. I don't know what he's done to it but I'll find out.

next time you see him, call his truck a 454BS cause stock, it isnt capable of beating vette's. I would say its a 15/16 sec truck. Yes it has the potential of going fast but if you guys are still in school i doubt he has the funds to do it.

It will run 16 flat stock. The biggest restriction on this engine is the TBI unit...a good MPFI unit would benefit these trucks big time. Don't worry about losing to him; cause i wouldnt

tpivette89

haha, a vette beater? NOT!!! one of those trucks ran my corvette at the track last year and went 15.7. im 2 seconds faster than that. tell your friend "good luck"

CODY BEHNKE

I beat this guy in town all of the time. He can do cool burn outs but thats all. Last year he ran a best of 15.9 with a K&N and Flowmaster muffler. There still neat but a 454 has a small power band. It's kinda like my S-10 SS, GM should've made them alot faster. After all they are SS's.

BadBowtie88

You are sort of right. At a standstill you will probably kill him. But, my friend had one of those trucks, and I was with him when he beat a 95' Vette on the street at a roll. I hate to burst your bubble, but, they can be vette killers. He only ran a 15.2, but, that was traction. The potential was there.

much like the stock TBI in f-bodies there are two really lame restrictions from teh fatory that are easily replaced for huge gains.
1. the stock exhaust is a joke. the factory y-pipe is undersized and meets at a 90degree angle, it uses an opld style, highly restrictive, pellet style cat, and an under sized and compression bent cat back system. the solution is to get 3inch tubes off the manifolds, a (2) 3inch into (1) 3.5 inch y-pipe, 3.5 inch cat, and a 3.5inch cat back with a high flow muffler(flowmaster 1 chamber anyone)
2. the factory air box is restictive and has many twists and turns. the solution is to get a 14x6(yes 6inch tall ) open element. it will fit below the stock hood and it eliminates the two air silencers and the undersized snorkel(the snorkel actually has less flow ability than th ethrottle body) as well as teh moisture trap(if any water made it that far up the air cleaner you have much bigger problems, like getting the truck out of the lake)

most of these trucks came with 3.73 gears, soem got 4.10's the last few years, they are all posi, and they have bullet proof 14-bolt rears.
they are not the greatest from the factory, running in the 15.7-16.1 range, but it only takes these two little changes to make them into a low 15sec truck, traction limited because of the huge torque. they are very respectable from a roll though.

Ok, I've got no clue about these vehicles, what years were they made??

mygrain

Their cams were a joke as well. I looked the specs up for a friend and they were the same as my dads winnebago motorhomes 454. How pathetic is that?

they're ok top end, i still haven't lost to one...from a roll or a dead stop....and my car only runs high 13's.

to call one a vette killer is downright comical.

BadBowtie88

fly89gta: Just b/c you haven't lost to one, doesn't mean they are not fast. It's just like anything else that is detuned from the factory. My friends truck only had a small compucam and headers and he beat a 95 vette, not very comical for the vette driver. If you find one modded I would watch out.

anything that runs mid-high 15's isn't fast in my book...especially with the SS nametag. A cam and headers damn well better make it quicker. Just because it beat a 95 doesn't mean its fast. I mean hell i beat a '00 WS6 once, doesn't mean my car is fast. We all know a '00 WS6 is faster than my car, just like the vette is faster than a slightly modded 454SS. Driver skill or lack thereof has a lot to do with it as well

HrdRockA4305

They've got mad torque I'm sure, but I've heard they still only run 15s. You'd think a 2WD shortbed with a freakin big block would be a lot faster, but in reality the 454ss motor is like a very large LO3. Small TBI, bad exhaust, and probably a cam and heads package just as bad as mine for the size of the engine. I'll bet they're fun to drive though.

tpivette89

definately not vette killers. they run 15s. any TPI vette will be able to at least run low 14s, so that just doesnt add up. LT1 vettes are in the mid 13s, and are pretty good from a roll (i run a 13.6, and tried to pass a LT1 vette at about 40mph. the LT1 driver realized this and downshifted, and i couldnt catch him). the guy in the 95' that got beat by a 454SS that was mentioned earlier either couldnt drive or wasnt racing. even with a cam/head swap should put those trucks in the mid 14s. thats just about par with the early C4s. and if its a LT1 vette? no contest. believe me, ive raced these trucks, if your running in the 14s or better, you have nothing to worry about.

ZL1day

heads cam and carb and youve got an 12 second truck on slicks....come on guys this is a 454 we're talking about here. Take out the restrictions and 450-500 horse is very doable....only wish I could afford to build one

HrdRockA4305

"....come on guys this is a 454 we're talking about here. Take out the restrictions and 450-500 horse is very doable"

Thats exactly my point. Its not making anywhere near its potential because of all the restrictions on it. Which is too bad cause that truck could do so much more.

I'm sure that he is beating vettes, all of us here can. All you have to do is find those old retired guys that have never had their "babies" past half throttle. I get that a lot down here in Naples, FL AKA retirement capital of the world.

Mike92

There are usually a few at the track with slicks and hopped up engines running high 12's or 13's at 100-108mph but they sound like they have open headers and if they had street tires they would be at least a half second slower.

85transamtpi

I find it interesting that you guys are calling that TRUCK any sort of fast. Sure its got torque...if I was looking to pull a tree stump out of my front lawn, I'd look no further. But to say that "from a roll" or any speed the truck is fast is far from true. Also keep in mind that the front of the truck can be compared to a billboard...not exactly streamlined. I doubt if that truck could hit 130mph. 255hp aint gonna kill a vette...unless you are talking about a smogged out cfi vette, that needs a tune up.

IROC-ZWV

you wont catch me saying anything with a 454 is not fast...it would rape my and my 305.

Ghour_Demon

255hp from a 454!?! WTF!!! You've got to be kidding, I thought they always had at least 300hp.
Im not into rice and not fanatical about 100hp / liter engines, but
34hp / liter is very sad, you might as well by a diesel...
I consider a good performance machine to have as many horses as cubes with torque to match.

TriGenRS

Its a truck engine. Its not made to make horsepower and go fast. It makes torque to pull/carry heavy things. The BB's in camaros/firebirds/vettes are a different story since those are performance cars.

HrdRockA4305

"Its not made to make horsepower and go fast."

This is true, but the thing is its supposed to be a performance truck. Its just got a regular truck 454. Kinda like the LO3, its not really made to be a performance engine, its made to power the low GVWR trucks and caprices.

I guess from a manufacturing standpoint though, putting the largest gas V8 you make in the smallest fullsize pickup would be the easiest way to make a powerful (well torquey at least) truck without really putting any R+D into it. Its still too bad though that anything with "SS" badges runs 15s IMO. I'd probably be a great tow vehicle with that torque/weight ration, but I dunno what its really rated for.
