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.

Never argue with an idiot. They will just drag you down to their level and beat you with experience.

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

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.
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.

Let me know if you want a set of 2in primary hedders for the LS7… 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! So has that LS7 Monte been shot for a magazine yet? 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 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. 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. 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. WOW!!! How cool, thanks! Do you have a place to pull some dyno numbers around you? I have access to unlimited dyno time at a friend's personal dyno in his garage!
