Hpw much is that puppy going to cost you?

LS6 is the same as the LS1 just a few different things.Guys do LS1 swaps so I say it is possible.It probaly would be cheaper to buy the LS1 and do the LS6 upgrade yourself.

From what I have read, the main problem will be the oil pan. The Corvette has a wide flat Oil Pan, but that should be able to be replaced with a LS1 pan and oil pump.

I was told that the 3.4 engine compartments are smaller and thats why the frontend was redone on the LS1. It may be able to be done but it would be a tight fit.

You are correct. The LS1 would not fit under the old design of the hood, hence the redesign.

Simply fix is a Ultra Z hood and functional ram air. The Z06 engine is different from the LS1 or LS6 engines...it has D-shaped exhaust ports and a more aggressive cam than the regular LS6 or LS1. It will fix however with the right parts (crossmember, mounts, yada yada yada).

i have seen one on ebay starting about 3,000 just the engine, no tranny, electronics or any of the other good stuff that is needed. its going to be a pretty big expensive project if i decide to do it considering i hav automatic transmision, and i would have to redo the drive train and rear end and alot of other fun stuff.

uuuhhhh....the Z06 and LS6 are the same thing the Z06 is the corvette that comes with the LS6 engine. if people can get an ls1 in there then you can get a ls6 you just might need to change your front end to the 98+ style.

ok... here we go... I've already done about 3524525145414 hrs researching this topic speciffically! BASICALLY, all you have to worry about is if an LS1 will fit, since the ls6 is the same block! What I'd do (doing) is look for just the block... do some work (bore and stroke) then get LS6 cams and all the internals. you'd have to get a tranny to go with it! there is no option, HAVE to. Right now, the only option we have is to get the vette PCM too, its the only thing that'll control the engine perfectly.. since ours are watered down for the v6 and there is no way to program it. MAYBE we could flash it with the vette options, but I didnt research that. Anyway here's the very first link that I found back in my day... I now have like 15 bookmarked in an 'LS6 Swap' folder [img]smile.gif[/img]

The LS6 engine found in 2001 and newer C5's and F-Bodies has an LS6 block and intake manifold with LS1 heads (oval exhaust ports).
The LS6 engine found in Z06 Vettes is a LS6 block, LS6 intake manifold and LS6 heads (D-shaped exhaust ports).

nah brother, you're wrong... no LS6 engine is in an fbody, its the LS1. LS6 and Z06 engine are one in the same my man!

Absolutely wrong...even SLP will tell you that the LS6 is in the 2001 and newer F-Bodies. I wil be happy to scan the parts microfische for each of these cars if you would like me to prove it to you. I am 150% sure of this because I am also doing a LS6 engine swap into my '93...this besides the fact that I own a performance parts company and deal with these engines everyday. You guys can listen to whichever opinions you would like, but I have GM written proof here if anyone would like to see.

[Fin]

Josh, not to flame you, but I'd like to see your 'written proof'. Most of us are aware that GM started putting LS6 intakes on newer (either '01+ or '02 LS1's), but there was very little else done to make it an actual LS6. You can purchase the heads, & whatever else may be needed, but an LS1 & an LS6 are still 2 different motors. If the newer V8 F-bodies shared the LS6 w/the ZO6, why don't they pump out closer numbers?

The modification from the LS1 to the LS6 block was a PCV tube routing that GM did to the block. there was a major problem with oil comsumption with the LS1's...it was being pulled through the PCV tubing and sent into the TB, essentially sending a small amount of oil into the combustion chambers. GM redesigned this block with a simple, small modification in the lifter valley in order to be able to use a new valley pan which could fix this oil problem. The new PCV system uses a small U-shaped tubing off of the front of the valley pan to the TB. The underside of the valley pan has a pickup that will not allow oil to get sucked up and pulled into the engine. The old, LS1 style PCV system had all kinds of tubing under the intake manifold and near the valve covers...this was ALL eliminated. Otherwise, the LS1 block and the LS6 block are the same.

Furthermore, the Z06 puts out more power due to a more aggressive cam, which I stated before, LS6 heads which flow better, which I stated before and after talking to our Vette tech, they also used a different computer tuning in the Z06 and larger injectors in the Z06 (28.8 #). Using these upgrades, of course the Z06 will put more power out than the standard C5 or F-Body LS6, let alone the LS1.

One thing I will correct myself on is that I am not sure if the LS6 block was introduced into the F-Body in 2001 or 2002, but I know that they definitely had it in there in the 2002's with te modified PCV system.
