Thank you for the kind words guys
The newer LSX motors can be made legal in CA and CO as well. The guys doing swaps on the west coast have figured it out and have been doing it for several years. The information I have read all pints to it being very county specific as to what the "referee" expects to see. I have even read where a swap was failed because the CAT was farther away from the exhaust manifold on the swap than in the donor vehicle.
Dollar for dollar I think that the 5.3 is currently the best bang for your buck. I get a chuckle when I read guys talking about how they NEED 400HP from the swap or it is not worth doing, in a 60 or 80 series for **********************. The Vortec motor in the LC is pure and simple, a game changer. You ask most any LC owner and if they are honest, with themselves and you they will tell you the biggest draw back to their truck is it being under powered. A V8 with in many cases more than double the HP of the original tractor motor makes the owner have to look for something else about their LC that might be a drawback. The truly funny part is, LC owners go ga ga over one with a Vortec and that low hot rod rumble while soccer moms across America take their kids to school in their Tahoe and think nothing of it. Guess it all depends on what you have grown accustomed to :smiley_drive:
