1971 GMC LWB
489BBC
4373lbs. with driver
10.77@124mph around 3975'DA

Have ran faster but was bracket racing and had to go hard on the brakes. Going off 60' and DA that day and way it was pulling thinking it was in the high 10.6's. This year planning low 10s at local NHRA track, and hoping for a 9sec time slip at outlaw track just to say I have with proof in hand.

Re: post em up....
 

72 LWB
468 w/150 shot
TH350
4.56 12 bolt

7.36 Best 1/8th ET with a 4.10 rear. Haven't ran it with the new rear yet. I'm putting a nice 496 together for it as we speak.

Re: post em up....
 

Are you squeezin that heavy dude?

Re: post em up....
 

Running a 150 shot right now, will likely go to a 175 shot for bracket racing with that and banking on my new carb and fuel system to take care of a few issues I was having to put me in the sub 10.5s. As far as the outlaw track thinking really hard on trying a 250 shot run and see if that's enough or not, might not be but trying to be optimistic.;) It'll happen some day, 2 year plan for a all aluminum BBC 540 or bigger shooting for at LEAST 750hp motor with a 4150 and 11:1 or less, once again might be a bit optimistic.:lol:

Re: post em up....
 

Nope...not optimistic at all, you can get close to 730hp with a 496 on pump gas with a 4150. Oh yea, off the shelf parts and unported heads.


However, I was thinking you might be a little on the sarcastic side...lol

Re: post em up....
 

Ok...umm....I call BS. While 1.4 HP per cubic inch can be done with out a ton of work, I'ts not going to happen with shelf parts and pump gas and a baby 4150 carb easily. Maybe with some 315cc AFR cnc heads, 11-1 CR a nice solid roller and a 150 shot. My bud has a 505 with 12-1 and eldebrock roval heads, solid roller... a pretty nice combo over all. Dyno'd at 645HP

Re: post em up....
 

OH YEAH!...I have a freind who's uncles friends brother just so happens to have a 60somehtin Impala with a 327 with 600 horses and it runs 10 flat..................JUST KIDDING! JK JK JK JK JK JK JK....

Seriously though you guys have some very IMPRESSIVE trucks. Great Job to alll of you. I am envious. After my kids(2yr old and a 2mo old)get a little older, then I will start a drag car/truck project.

A good tuner can get 720 or so out of it.....box stock carb with nothing more than different jets, unported afr 305's and off the shelf cam offered from jegs.

Imagine what the afr 325 CNC head will do.....750?

Re: post em up....
 

I hate to say it but 645 from a 505? 12:1 and solid roller......there is something very wrong with that picture. Needs a different head if you ask me.

Here is another one for ya .... this one makes less power but it is also hydrolic cam and a different set of heads with an airgap.

http://www.popularhotrodding.com/fea...lle/index.html

720 or so is very doable with off the shelf, pump gas components.

Re: post em up....
 

That was on a REAL dyno,not some made up..need to sell parts...magazine fiction story.
Yes the heads are the limiting factor. How much does the GM 572 make?

Re: post em up....
 

My 431 big block iron head rectangle port dynod 684 to the flywheel on a real dyno and a proform 950 carb with a 680 lift solid roller. Bought my motor from awsome engines.

Re: post em up....
 

The GM 572 crate is a turd and designed for a warranty. I'd be willing to bet anything that with a good tune and the right parts combo, it makes well over 720. I did not know the magazine articles used fake dynos.......

720 on pump gas with off the shelf parts from a 496 is very doable and I'm not justifying the articles......what makes that so hard to believe? I saw a 509 with a small flat tappet cam unported 990's make 600hp @ 9.5:1 cr.

Re: post em up....
 

Those ar great numbers. Have you ever raced it? If you have I'd love to see the numbers. 684HP would put at about 125mph in the 1/4

Re: post em up....
 

Re: post em up....
 

I appologize for being so snippy. It's just one of my pet peives. Magazines and TV shows inflate their numbers...it is well known. They have to sell the parts they install. If it didn't make good numbers who would buy them?
They are not fake dynos. Anyone using a dyno can make it say what ever they want. Just be fudging the correction numbers. This how Ebay dealers sell 700HP BBC for 5grand..It's complete bull and it pisses me off.

Re: post em up....
 

according to online calculators it says your making 500HP
Your Horsepower computed from your vehicle weight of 4000 pounds and MPH of 115 is 500.00.

Re: post em up....
 

Haven't even played with the jetting yet, and it might do 125 in the quarter if it wasn't almost a 4000 pounds and the aerodynmics of a school bus.

Re: post em up....
 

I do believe that some folks lie to make a sale ..... especially on sites like ebay. But I have read so many stories of a radical 496 I just couldn't believe that setup didn't make much power. It's a very popular combo. JMO

Re: post em up....
 

I believe that's mabey 500 to the rear wheels i don't believe those online calculators anyway because you can get alot of differences. I also believe that my truck should run better with those kind of numbers, but i think some of the problem is traction, tunning etc.etc. I think there's 11.00 in this thing, and if i dip in the high 10's i don't really care how much hp i'm making, that's fast enough for me.
