CELEBRATING 20 YEARS!

I have scene these motors be abused in stock applications to the most extreme builds and only need the oil changed. These are great motors and the only reason that the salvage yards have some many of the truck motors at good prices is they don’t break! Salvage yards cant give these engines away for a stock replacement motors because the LS series engines lasting well over 250K. You push close to 500+ HP on the 6.0 with the L92 heads and still be completely streetable and reliable on pump gas with 20+ MPG if you go FI.

Id stick a used LS6 cam (01-04 Z06) about $120, LS1 ($80) or LS6 ($200-$350) F-Body intake or (GM Carbed) and L92 heads and run it till the wheels fall off. When the time comes you can always stroke that 6.0L, but for right now you can have a 500hp stock shortblock that will be great on gas!

On the truck accessories if you don’t run the large A/C compressor and use a 98-02 Camaro/Firebird alternator you can slide them in most applications. All the car style accessories clear with the BRP style conversion kits (GTO needs 98-02 F-Body alternator).

When you’re looking for drive trains make sure to get 2wd trucks or else the 4l60E cant be converted to 2wd. The LQ9 is the HO 6.0 that was available in the Escalades and makes considerably more power then the lower compression LQ4.

I also have a friend who has a wreaked 16K 2004 black on black GTO LS1/4L60 if anyone wants any info on the car PM me and I can get you his contact info

Thanks
Phil

2007 L92 5K miles $4500 complete with warranty with ECU this is the VVT monster that makes over 400hp stock in the new escalades

Better check your local laws before swapping in a truck motor, in some states there are legal issues with swapping a truck engine into a car since they are in two different low emission classes.

The LS engines far more environmentally friendly then any older GM V8s. I have had several customers install these in G-Bodys in California and all over the west coast where they still have to pass emissions. Its hard for them to sneak long tube hedders on the car but i have heard of no issues with using the truck motors . If you are worried about passing emissions hook up some cats and run the stock ECM and you have a engine that will meet modern standards for emissions

My employee at the shop decided to sell his 85K mile 2001 Z28 LS1 (LS6 intake) T-56 6-speed drivetrain for $3800 that’s at my shop in Cumming GA, that comes with any parts you need from the donor car other then the brakes and interior. Its pulled and ready for pick up for to be shipped

Thanks Phil

Here is some photos of my employees 85K 2001 LS1/T56 combo and that comes with all the hydraulics and a uncut wiring harness and ECU







We also have a 45K mile 97 T-56 that’s been laying around the shop for a while that’s great for using on older Gen 1 small blocks and big blocks. We have not had a Gen 1 engine go through the shop in 4 years so its only been collecting dust. $1500

why would i need a different alternator for the truck accesories? the truck accesorie alternator is in the traditional spot on the drivers side?

Yup, the truck alternator is on the driver side. It sits so high though that hood clearance may be a problem.

i guess i didnt think about the hood clearance, but looking at the accessories on my 2003 gmc truck, they dont look that high, i guess it wouldnt be that big of a deal to swap out alternators though, then id have a back up for my truck!

That F-body alternator is a direct replacement and be found at any parts store so it’s a easy swap.

I had a couple PM for just motors so here is a couple

6.0L LQ4 with around 40K-50K miles $1950
5.3L LM7 all aluminum 27K miles $2000

all hedders for the G-Body are in stock now and off the first pre-order, the special order stepped hedders will only have a 10-14 day build to spec process.



Thanks
Phil

Phil, very nice kit! The headers look awesome. I'm glad to see someone finally offer these for the LSx G-bodies. These motors make so much more power with good long tube headers! Good luck with your new product line!

We need a sticky for this thread, alot of useful information that i bet alot of guys are going to be using, i know i am!

John,

Thanks for the nice words, there’s a lot to choose from in this new line so I made sure the G-Body was the first car I made hedders for because of the weak aftermarket for the G-Body’s. So has that LS7 Monte been shot for a magazine yet? It’s a very nice car that has had some great pics floating online for the last few years. Let me know if you want a set of 2in primary hedders for the LS7…

Also on the hedders I just had a customer from LS1tech use one of the first set in the stock location with the stock driveshaft with no mods to the hedders and very light trimming of the LCA. I have him getting some pics for me know.

I hope this thread helps and post any questions you run into and ill be happy to help or call BRP at 770-751-0687


Phil

here is a pic of the C5 corvette fuel filter regulator with the needed fittings

That would be me, Im gonna clean the car up and get some pics and info this weekend for you guys. Overall, wasnt a bad swap once I squared away all the parts.

Good idea

Phil, I'll have to give this very serious consideration. People just don't realize how expensive it is to make a one-off set of headers and the fact that you guys offer these at the prices you do is just awesome, my headers in just materials & welder (using all my labor at no cost added) cost me over $600! Yours are very competitively priced!

I had two large publications make commitments to do an article on the car but neither has followed thorugh...oh well, I guess not enough bling factor....no flames, no wild interior, no additional chrome under the hood, etc. I don't mind seeing these on other people's cars, just not my own. I prefer the factory sleeper look with the only giveaway being the stance, sound and exterior look. Even as the car sits now, I literally get embarressed at places like the track because everytime I have to crack the hood to let the car cool between runs, people want to see what's lurking under the hood and it's like a pack of flies on doo! What's really funny is all the compliments I get about the car everytime I stop at gas stations or the store and people don't even know what's under the hood

I'm like you John, I hate chrome and like a retro-mod kinda look. I love how your swap looks like it seriously came like that. Besides the Corvette logos on the coil covers you'd never know.

John,

I sent you a PM about some hedders get back to me if you ever think about it. Those 2in primaries will open up those exhaust ports the LS7 heads.

I’m going to send some info about your car to a editor I know at Chevy Rumble we have been talking about some LS powered Montes so you never know. I’m putting a tech article together called the “LS Quickie” as a weekend LS carb conversion on my 86 Monte. There a growing interest in the G-Bodys and that LS7 makes a statement and I have always liked a clean look over the flash. Do you have a place to pull some dyno numbers around you?

Thanks
Phil

Phil, could you please resend the PM? I didn't realize that my PM box has been full for the past year....DOH!!!! I just emptied it so that I can receive more.
WOW!!! How cool, thanks!
I have access to unlimited dyno time at a friend's personal dyno in his garage!

Sent you a PM back about the hedders,let me know what you think

I have a set on the 2in LT in the shop ready to ship...

Well Phil,

Sounds like I'll be getting in touch with you. Tonight I acquired a complete low mileage 2004 LQ9 engine. Now... decisions decisions.

Congrats on the LQ9 shoot me a PM with what your build specs are and we will get a kit and hedder combo that’s going to work best on your Monte.

Thanks
Phil

this a godsend for monte lovers

just out of curiosity if you were to use a 5.3l and carb setup how much do u figure the total cost would be?
