f-body ls1 vs. corvette ls1 vs. ls6 what is the difference between the f-body ls1 and the corvette ls1. Also is the only difference between the corvette ls1 and the ls6 the valves? i'm planning on finding a wrecked f-body or corvette for under 5000 to use a lot of the drivetrain in a 240z. It will have the weight of a japanese car and the power of chevy. It'll run 12s.

Re: f-body ls1 vs. corvette ls1 vs. ls6 12s? More like 11s if you put good tires on the 240Z.
Corvette vs F-body LS1:
-exact same heads
-exact same block
-exact same crank/rods/pistons
-exact same intake manifold
-slightly different cam specs (negligible)
-different shaped oil pan
-different serpentine belt pulley layout
Corvette LS1 vs LS6:
-different head castings (LS6 flow slightly better stock)
-different intake manifolds prior to 2001 Corvettes. All 2001 and newer Corvettes and F-body LS1s have the LS6 intake.
-different cam specs (02-03 LS6 cam is much better than 01 or regular C5)
-different PCV system
-slightly different block internals (crankcase port windows larger on LS6)
-same crank and rods, I believe pistons are a bit different

Re: f-body ls1 vs. corvette ls1 vs. ls6 I hope your right about the 11's but since a stock camaro weighs about 3400 and runs mid 13's if you use 100lbs equals one tenth in the quarter I am estimating that a 2000 lb z will be in the mid to low twelves with some good rubber wrapped around some 17 x 8 wheels. But back to the original question. Are you saying that pulleys are the only difference in the f-body ls1 vs vette ls1. I am leaning toward a camaro because i have found a couple with bent frames and destroyed bodies that have perfect drivetrains for around 5000. I am thinking my best bet is the f-body set up with a bad *** cam. I think the ls1/ t56 setup in a z should at least if nothing else a lot of fun. If you have any other ideas for a z i would love to here them. I am only 15 so i have till next april to get it running.

Re: f-body ls1 vs. corvette ls1 vs. ls6 Yep, basically the pulley layout and the oil pan shape. Corvettes have a flat oil pan with "wings" on the side, which don't really fit in any other vehicles very well.
There are quite a few bolt-on LS1s running mid-high 11s with no internal engine modifications, all in the 3100-3200 lb range. 2000 lbs is way light!

Re: f-body ls1 vs. corvette ls1 vs. ls6 The location of the alternator is different which is what I think Tony means by pulley layout. F-body alt. sits driverside, opposit the a/c compressor. Vette alt. sits driverside topside. Also, the crank pulley are slightly different.
Sounds like you've got the makings of a pretty basass little ride.

Re: f-body ls1 vs. corvette ls1 vs. ls6 thanks for the help. I am pretty sure i am going to go with the camaro because of price. I am pretty sure i am getting a z but my dad has a lot of input and he has told me i cold get a z in the past but i will definatley have to hide these numbers from him till its built. by the way what bolt ons are guys using to run 11's.

Re: f-body ls1 vs. corvette ls1 vs. ls6 I'm no expert here, but LS6's have magnesium valves too to reduce reciprocating weight correct? Tony you'd probably know if that's true or not. I'm pretty sure it is.

Re: f-body ls1 vs. corvette ls1 vs. ls6 I think the LS6 valves are hollow stainless steel and the exhaust valve is sodium filled for cooling (valve stem pics http://www.idavette.net/hib/02ls6/photos/43106b.jpg). Here two versions of the same article about the LS6 development from a GM engineer.

Re: f-body ls1 vs. corvette ls1 vs. ls6 Magnesium Valves?!!! Since magnesium is flammable ( i.e. magnesium flares), I don't think so. Wheels, suspension, etc., maybe. Engine parts (at least around the combustion chamber), No!!
