anyone has seen in our family of trucks? I was just curious to see some of the wildest, pin you to your seat motors that have been shoe-horned in these trucks.

OARNGESI · 09-03-2009, 12:35 AM

CHECK OUT THIS TRUCK ANYONE KNOW IF HES A MEMBER

YouTube - 640 Hp c10 burn out

DMARCUM123 · 09-03-2009, 12:41 AM

i have a big block stroker dyno at 625 hp in my 71

nicolas72gmc · 09-03-2009, 01:11 AM

Hey D, do you have pics of your motor?

**special-K** · 09-03-2009, 07:46 AM

I love seeing one of ours on steroids.I built a pro-street`70 Stepside that dynoed @600hp+/-.It was a warmed up LS6.I`ve known of way more than that these days.But,that thing sure did rumble and scoot.Unfortunately I barely had it done and financial woes forced me to sell it,since it was fresh and brought good money.
I started another and the same old blues hit me,along with other changes.So,Project Poor Boy emerged as a 350 horse cruiser.

Sinister · 09-03-2009, 07:54 AM

A lot of nice trucks/motors in the Racing and High Performance section of the Board.

**SactoJim** · 09-03-2009, 11:04 AM

This has got to be the wildest...

**Hart_Rod** · 09-03-2009, 11:24 AM

I've got a 383 stroker with a vortech supercharger in my 68 SWB that dyno'd 675.....

Longhorn Man · 09-03-2009, 10:17 PM

that turbine powered gmc was the first that came to mind

71tahoe · 09-04-2009, 08:43 AM

First one I thought of was the diesel powered drag truck.

MXmaniac · 09-04-2009, 07:28 PM

Dang, SactoJim beat me to it.

I am always amazed at what people do to trucks
There is a member here in Houston that is over 800 hp maybe he will post

big_al_71 · 09-04-2009, 09:07 PM

My built 406 has plenty of power and it breaks the loose at any speed below 50..my set up should be at right around 400hp to the wheels. Not the wildest I have ever owned but definetly a great sleeper.

BCOWANWHEELS · 09-04-2009, 10:51 PM

Sounds like ear damage to me. Once you loos it it isnt comming back and you will miss it..... Sperience

capev86 · 09-05-2009, 12:35 PM

got a low mile rebuilt 406 going in my 72 burb 3/4ton 2wd. it ran like a son of a gun in my dad's 84 burb 1/2ton 2wd.....like a big camaro. but yes, there are much bigger and meaner rigs out there. stacie david's 67 super big block powered truck has like 630hp naturally aspirated and will leave a rubber patch all the way down the track. there comes a point that the power over a certain level is purely academic (bragging rights tied to wallet size) because street going trucks don't have the aerodynamics necessary to make complete use of that power (high speed driving). if i had tons of money and wanted the ultimate tow rig i'd put a brand new duramax 6.5 (keep it GM) w/ the best banks kit and allison 6 speed trans in my truck.

*Dylan · 09-05-2009, 02:33 PM

How much do the 572's put out from GM? If I remember right there's a guy on the board that has one in his truck.

capev86 · 09-05-2009, 03:21 PM

the new generation big block 572 crate motor has 630hp on premium gas. i think it is something like 550 on 87 octane. absolutely overkill on one of our trucks....but totally awesome. it would pass everything but a gas station!!!

howard_m18 · 09-05-2009, 03:37 PM

Do diesels count? Over at the diesel place they have the trucks listed & here is the #1 winner.

"COPPERHEAD" is a 67 that had the very 1st. #572 ever put in anything. Here are the figures for the truck& its engine. Here is the link:

http://www.gearztv.com/projects/copperhead.html ENJOY!! Howard

capev86 · 09-05-2009, 05:42 PM

there is debate over who got the first 572.....stacie or jay leno. if you check out the big dog garage you will see jay's tri-five (buick) with the same engine and he claims he was the first. he does get his hands on a lot of beauties when they first come out, but i heard about this motor years ago when the copperhead project was still being built (on powerblock/trucks)....so i tend to side with stacie's claim.

bdydrp97s10 · 09-05-2009, 06:00 PM

yah stacie david had that 572 like 4 or 5 years ago.. im not sure when jay leno got his but, stacie david was the first one i ever heard of

Diablo de la Noche · 09-05-2009, 08:16 PM

Just a newbie question from a guy who hasn't been a gearhead for long...Can you put all that Hp to the ground and make it stick? (apart from spending $10k on a whole new, super high tech setup) I like the acceleration, although the rubber left on the road is quite impressive.

jmmm229 · 09-06-2009, 12:03 AM

my cousin just built a duramax and allison for a 70 model that made 900hp at the rear wheels. i have no link, but you can go to youtube and do a search for "nastygirl" and "merchant" its a crew cab 4wd 3/4 ton chevy with a duramax making 1004 hp at the rear wheels. my cousin built that truck, merchant automotive in zeeland michigan

chevymad · 09-06-2009, 03:39 PM

Wasnt there someone building a truck with a 900+cid schubeck engine here a few years ago?

howard_m18 · 09-06-2009, 04:16 PM

My reply on the diesels above mentions the name "Nastygirl!." Did you ever get a chance to ride in it? Howard
