I feel these relpies appear mostly out of jealousy, i think we should just give people props where they are due and bite your tongue when there are issues or trends you disagree with.... I see things daily on here that have me either scratching my head or wondering why some one purchased every POS from the JC whitney book and slapped it in there truck... yet I say nothing because if thats what they like and want to shell out cash for then oh well...

thats my 2 cents...

WELL SAID IT'S LIKE MY LATE GRANDMOTHER USED TO SAY....

Hats off for Norcal_guy73!!



I see perfectly good trucks posted just for people to have a hey day to pick apart. We are a board of truck lovers... leave the hate for another board!

This thread in particular... A dude has spent more than a lot of members will ever make in one year. Why sit around trying to degrade the symantics of his verbage? That is one fine ride, that none of us here would kick out of our garage... if we had one

Soap box off.

I really don't see anybody trashing the guys truck though. Many people have said it is a beautiful truck and I agree, I only hope mine will look that good when I'm done. The only thing that people are debating about is the claim of 600rwhp. If he is making that, it is wonderful. But to exagerate something like that after doing that much work is just dumb.

Thats my 2 cents.

I agree with you haywagon, no one is trashing the truck in particular. Maybe the original post should have been what a nice truck this guy is selling. If the thread originater wanted to debate HP ratings on a Chevy 350, he might have posted a thread asking opinions on a particular set-up, and what we thought the HP rating might bring.

[72CSTC5]

For all we know someone built the engine for him and took all of his hard earned money and short changed him and told him his motor would put out 600 rwhp. Iv'e heard and seen people do it all of the time. That is why I had my motor dynoed before I left the shop with it to see what it would really do. I have a mildly built 355 and they claimed it would put out at least 475 hp. It only dynoed 421 hp. He has a nice truck and running and driving. Better than mine.

He also claims to have a Dana 60 rearend, but it looks kinda like my 12 bolt, but I'm no expert on this. I'm not hatin' on him, he has an awesome truck, I just don't know why he has to exagerate.

dtilly - I did say in my original post he had a nice truck, I was simply calling BS on his 600 RWHP claim. Why can't he have a nice truck and be honest about it?

Everyone - It really doesn't sound like I was hatin' on him. I said TWICE that he had a nice truck. I just question his 600 RWHP because I know it is BS. If I can't come on here and question something like that, while twice mentioning he has an awesome truck, without some NorCal smartass jumping on me, then I don't really know if you folks are the kind of people I want to hang out with.

And yes, my truck is a pile. I am not jealous at all because he has a nicer truck. I could care less how mine looks, it's just an old work truck. I signed up on this board to get info on keeping the POS running, not to make it cool. I look forward to the day that I get to run it in a demolition derby!



And hear it is. Rusty, maybe 160 hp, exhaust leaks, the 2 piece driveshaft is about to fall out, only about half the stuff works. Why can't people just be honest about what they have?

[67ChevyC10Stepside]

dont you guys think this has gone on long enough?

[1972]

I though it was going fine until someone from the all important NorCal region questioned our ability to question someone else. I'm done.

[67ChevyC10Stepside]

i just dont understand why it is that important to you guys to make a fuss over it.....as has been said....it's possible...it's not likely but it's possible....now short of talking to the guy and getting proof there is no way to prove or disprove it....it is a awesome ride no doubt and i dont see the point of fighting about it...if you are going to buy the truck you have the right to question it....but since you aren't....what does it matter? i dont know why you guys can't just say....nice truck. and be done.

[screamin_c102]

Nice truck!!... I'm done

[CPNE]

Time for the Barney Board Song once again kids:

I love you
You love me
We're a happy truckin' family
With a great big hug
And a kiss from me to you
Won't you say you love my truck too?

I love you
You love me
We're best friends
Like friends should be
With a great big hug
And a kiss from me to you
Won't you say you love my truck too?


Gotta side with 1972 on this. There's nothing wrong with a little debate, it educates us all. Furthermore I didn't read any malicious remarks.

[FirstGen]

These threads are so entertaining. Incredible truck. Looks to me like the guy has some money and threw alot of it at the truck and the result is very nice.

I would guarentee that that combo is not making 598 RWHP.

I'll believe it when he posts a dyno graph. Believe me if he actually dynoed it he would be very proud of those numbers and would probably have it posted on his site.

Also, the rear pictured on the car domain site is in fact a 12 bolt.

[67ChevyC10Stepside]

firstgen...you are one person i will ask this question since you have dyno numbers etc....what lets you guarantee it wont work....your motor is a escalade motor you said and it's got 608....so why can't a what is it 12:1 aluminum race motor?

[1972]

I'll let him answer in detail, but I bet "608 RWHP on the juice..." the on the juice part has something to with it.

[67ChevyC10Stepside]

yes...i understand that....but from what i recall his is a escalade motor with nothing too radical done.....a little different than a 12:1 aluminum race motor...

Ummm...I live in NorCal....lets not lump everyone in your slam..call a spade a spade if you want. I too think his 600 rwhp is bull, as I posted his times reflect under 400. It sure is purty though.
(unless you were talking about me^^^^^^..then disregard my statements )

[Purs]

First let me say, it is a BEAUTIFUL truck that I'd LOVE to have. MUCH nicer than mine probably ever will be. However, I'm very happy with my project truck and feel no jealousy what-so-ever. I also don't like how people sometimes nitpick any little thing about peoples rides. However, I didn't feel like that was the case here, just calling BS. I will limit my remarks and just refer you to some information I pulled from a popular performance website, smokemup.com.

Information is straight from his car domain site, left of the first pic.

Bragging Rights
Quarter Mile: 12.6 s @ 116 mph->
0-60: 6 s
Est. Horsepower: 600
Weight: 3800

Here is a calclation that figures HP from ET found at smokemup.com

Vehicle Weight 3800(lbs)
Elapsed Time 12.6 (sec)
Drivetrain loss 20 (%)

Results:
375.5 Rear Wheel HP
469.4 Crankshaft HP

Here is what 600RWHP should equate to in a 3800.lbs vehicle, also according to smokemup.com

Vehicle Weight - 3800 (lbs)
Wheel HP - 600 (HP)

Results:
Trap Speed - 131.84 (mph @ end of 1/4 mi.)
E.T. - 10.77 (seconds @ end of 1/4 mi.)

Here is probably the most accurate way of telling horsepower, Trap Speed. Spinning or not, your MPH will be very close and is a very good indication of what kind of HP you are actually making. Anyway, here's the results:

Vehicle Weight - 3800 (lbs)
Trap Speed - 116 (mph)
Drivetrain Loss - 20 (%)

Results:
Rear Wheel HP - 402.7
Crankshaft HP - 503.4
Power to Weight (rwhp) - 9.4 (lower is better)
Power to Weight (crank hp) - 7.5 (lower is better)

If you think I've doctored the results in some way because I'm jealous, then please run the numbers yourself. http://www.smokemup.com/auto_math/hp_mph.php

you decide if the numbers seem optimistic.

my question is how "optimistic" does something have to be to be "misrepresentation"?

I will say once more, it is a beautiful truck, that I'd be more than proud to call my own.

PS. I looked for an email address (but didn't find one) to contact the owner to compliment him on the beautiful truck and to ask about the engine and how he arrived at the estimated numbers.

[NORCAL_GUY73]

well I guess my Nor-Cal butt is just so wrong to say people took this too far, hmmm I guess when i see those P.O.S trucks with ridiculous aftermarket doodads and false claims I will have to start pointing them out. I never agreed that it made 600 horses, although i belive there is a possibilty, but it probably doesnt. i was just sticking up for the guy. have you ever had someone on here beat you dowm verbally because of something you might not have even known was innaccurate? Basically i was just saying it isnt cool, but it just shows how us humans seem to always elaborate on the bad then soak up the good...
i'm done

[screamin_c102]

Geez this has been beat to death..

Maybe it's time to lock the thread before too many panties get in a not.

[FirstGen]

without spending alot of time on a pretty much worthless debate. Physically, a 750cfm carb will not flow enough air to consume enough fuel to feed 708 horsepower (600x1.18). That is one small reason it will never make 600 rear wheel horse power.

This is one of many different angles I could explain why it will not make that kind of power. The 750 cfm is a MAJOR bottle neck if everything else is not. You are only as good as the weakest link. You will rarely see a 750cfm make more than 400 RWHP with out severe lean problems N/A.

Also, what is a pretty mild setup on a modern (6 bolt factory main), sequential fuel injected, with a proper custom tune allowing for compensation on each cyclinder individually, a completely newer combustion chamber design and 14 degree head/intake design, is a TOTALLY different angle.

Simply put you will NEVER make 600 rwhp on a 750cfm carbed, dizzy sparked, simple combo, NATURALLY ASPIRATED combo. It just won't happen.

With 12:1 CR he will have to run 110+ octane to prevent detonation and he might pull down 450 rwhp range numbers with about 380 rwtq. I'd be surprized to even see those numbers on a dyno jet chasis dyno SAE corrected with a TH-400 and a DANA rear if he even does have it.

Nice truck, I think we would all have been just as impressed with saying he would like to make 600 rwhp one day...

On a different note, he could easily throw some juice on that thing and create some serious numbers 600, 700+ rwhp if it was tuned correctly.
