My Budget LS Engine Swap Guide <$1500
1. They tend to hang straight down, instead of being tight to the block
2. They have HUGE 3-bolt flanges.
I was feeling the same way about going with the 5.3L truck motor over the LS-1 motor for the huge cost savings between the two. Its amazing how cheap the 5.3 motors can be found now. I have seen them as low as $150 for them with a 90 day warranty on them. Most are 100,000 plus mile motors but that doesnt scare me to much.
I cant believe how many of these swaps you have done yet im a bit nervous to try one. Im sure after getting one out of the way it will go alot better.
Thanks VERY much for taking the time to write this up for us all and share your wealth of info, its much appreciated.

I`m going to bounce this up to a sticky for a while, and then I will let it float back down and put a link in the main FAQ sticky to it.
Nice write up and a lot of help.

Thanks,
Larry.

Just adding a spin on your Budget. You could use the old tranny? and Carb?
L33
The L33 was an aluminum block version of the LM7, and was referred to as the Vortec 5300 HO in marketing materials. Power increased by 15 hp (11 kW), to 310 hp (230 kW), over the LM7, and torque was unchanged. It was only available on extended cab 4WD pickup trucks.
L33 applications:
* 2005-2007 Chevrolet Silverado 1500 4WD
* 2005-2007 GMC Sierra 1500 4WD

There are others, but they are Flex-fuel, Active Fuel Management or feature variable valve timing, ca-ching!
