I have a question about flywheels. I have given thought about running an aluminum flywheel with the LS. I am going to run a bigger cam than the Z06 cam. What drawbacks or advantages are there to running an aluminum flywheel? I am thinking it will help the be more rev friendly.

I just got back from buying an LS6 with auto tranny out of a wrecked (on the side) 02' Camaro SS 35th Ani car. It's kind of dirty and has 95 k on it. Paid 2900 and comes with everything I asked for. I also picked up the dual fans for an extra 100. Not keeping track of costs....don't care....gp

I thought I corrected that with a later post. You are right, that would be an LS1. The 2002's in the Z28 and Trans-Am all had the LS6 intake and SOME had the LS6 block. If you get lucky, you can find one. I got my numbers backwards and thought I got an LS6 block but I realized later it was an LS1. Only slightly disappointed. Not a whole lot of difference. You can still really crank some HP out of an LS1 with some head porting, cam and exhaust. That's what I'm doing....gp

Negatory.
The LS6 was released with the 2001 Z06 Corvette. This was a 385 Hp version.
In 2002 the Z06 got a bigger cam with yellow valve springs and the LS6 went to 405 Hp. This engine was used through the 2004 Z06.
In 2004 and 2005 the 405 Hp LS6 was used in the Cadillac CTS-V.
In 2005 the Z06 option was dropped and the base Corvette got the 400Hp LS2.
In 2006 the Cadillac CTS-V switched to the LS2.
All 2001+ LS1's use the LS6 intake. The LS6 block is slightly stronger.

The Big Brown Truck Stopped by this afternoon and left a few goodies at my door. A little clean up and they should be good to go.

Jeff, its going to be at least this fall. Well, I did install the oil fill cap. I am not really concerned about the spring color right now, what I am most concerned about is whether or not they are the sodium valves. I plan on installing a set of Comp Cams 915 or 918 springs anyway.

I want to. Just got to make up my mind on what I want it to do for me. I would like to get around 400 RWHP and TQ. That would be about 150 more HP than I have now at the rear wheels. I don't really care about having a big lope. Just make it run smooth and powerfully.

How do you tell if you have the sodium valves? I guess you could weight them? I'd check over at ls1tech, I'm sure someone over there could just rattle off how many grams they should weigh.

Just out of curiosity are you going to use your tremec or are you looking for a modern 6 speed. I guess what I'm asking is can you mount the tremec 5 speed or an older 4 speed to an ls1?

Hey Tony. Long time. I plan on using the tremec behind the LS motor. From what I understand, you need an extended input bearing and a way to mount the z-bar at the motor side. I am going to order the Z-bar mount from Scoggin Dickey. That will be covered. The stock bellhousing will bolt up to the LS motor. There will be one hole that will not get a bolt in it though. I have not made my mind up on this point yet. I have been thinking about getting a bellhousing from Keisler that will bolt right up to both.
