The LS6 is basically a high output LS1. There used to be the LS6 degination on the old 454 big block engines but this is not the 454 version, it's the LS1 version.
@banginfiveohh ls5 is a 390hp option 454, ls6 is the 450hp option 454, lt1 is a true 350 with 5.7liters, and the ls1 is a 346ci 5.7liter. The 71 and 72 454s in chevelles were downgraded to 406ci and they lost the ls6 designation although the were still badged as ss454, and yeah the ls6 option vettes of today carry that ls6 option they are still 346ci with a little higher output than the ls1 due to some modification gm did.
My buddies WS6 ls1's block cracked so he just put in an LS6. He says its quicker and sounds better. He dyno'd at 350hp to the wheels. But your exhaust rocks!
The only issue he's had with the engine is cold starts, but that seems the be a problem with several of the LS6 engines. The only other issue is keeping a transmission in the thing that can handle the power. Even built trannys give him fits.
cant wait for my build to be completed...woot woot

"Your going to get about 20 mpg max" lol sounded like someone said that in the background

@davidyoung2117 That was my brother-in-law, who owns the car. He said he averaged 20 mpg on the trip back from picking it up.

@roxysbrian Thats not too bad, but I'm taking it that it was mostly highway miles? Still better than my 455 of course so I'm not hating lol

T/A's look goofy with no exhaust tips. Sounds pretty good.
