Default ls3 in a c5z06?

Does anyone know if you can get a ls3 crate motor with the ls1/ls6 reluctor wheel?

^^+1, although the LS3 is a much better engine in some regards, the output has been changed to 6.1 liters! The LS6 is simply the best 5.7 liter engine in my opinion, why the need for the swap?

Too many ls7's going kaboom for my tastes. It's pretty bad when GM has a special program that when your ls7 z06 blows they will ship it back to the plant for the motor swap. Several have been reported in the last 2 weeks. I will stick with a ls6 or ls3.

The 6.2 liter ls3 is much easier to get good power and maintain great torque. I'm looking for a track motor with 500+rwhp and 475+rwtq.

I was thinking of going the crate motor route and stick a nice cam in it to achieve my goals. $6k for the motor and $1000 for cam springs etc. How much will you have into the stroked ls3?

Why not stroke and cam the LS6? For all the pain and trouble and cost it just doesn't make sence to me.

hoping to stay under 8k but shooting to make around 600 RWHP NA



stroking and puting a cam in the LS6 isnt a bad idea either but im looking for shortest down time for my car, i can build my LS3 while my car is running and get to enjoy it still, then when motor is all done make it a weekend adventure

If this forged 402 hadn't fallen in my lap, I would have put an ls3 in. 485rwhp/460rwtq from an ls3 with just a cam and headers, ran a 10.84 at 128 mph(C6DVL)

I would think our C5 header would work. You would just need to ask for the ls3 flanges

I have an LS3 motor in my car due to my LS6 #7 piston exploding this year at CMP in April. I used all my accessories including the stock ZO6 intake which took a lot of work to get it clean. I have LG Long Tubes that were on the LS6 and move them over too. New cam, GM crank, 243 heads (polished/ported), CP Pistons, basically a forged bottom end. The shop however did not select the correct reluctor wheel. While we thought it was the cam sensor that was wrong we swapped that and it did not solve the problem. The problem is the car will not start the first time it may take 2-4 attempts. A big PITA! It starts but when I track the car it becomes embarrassing and annoying. I believe the LS3 reluctor wheel has more teeth that the LS6 one. A few things I did have to add. Ron Davis Radiator with EOC to reduce oil temps. This motor the oil temps shot up to over 300 while on track, hot enough to get the warning to reduce engine RPM's. If you don't track the car you likely won't need it, just be aware the temps are higher than what you would be used to seeing. Also I elected to put an Accusump in as well to keep oil pressure consistent while on track. And if 2008 was not a bite of the $hit sandwich I had to put a new tranny in (it died at Watkins Oct) so I put a RPM Level 5 with mechanical cooler!

LS2 create motor over LS3.

if you dont like the challenge with the LS7 creates you wont like the LS3s if you mod them.

Guys are having the same challenges

For modding go with an LS2 create or a 402 LS2 from Texas Speed, HKE or Ketech. You will be glad you did.

I only used the bare LS3 block. I did not go the crate route. I just felt the internals for what I use the car for were not up to the abuse for track use. The crate route for a pure street car may be a good choice and there are some great deals on crate LS6 motors. IMO it depends on what you are trying to achieve power wise and what are you doing with the car. The good news is there are a lot of choices so have fun picking the one that works for you!

The info below comes from Lingenfelter.

58x conversion module

--------------------------------------------------------------------------------
We have been providing pre-production units to some customers for testing for about 3 months. The product has been in testing and development at LPE for about 2 years. The first batch of production units made with production tooling were produced last week and will start shipping this week (week of the 1st of December).

Retail price is $254.95. It is on our web site and should be in our eBay store soon too. I expect some of our jobbers like SDPC, ws6store.com, byunspeed.com, Speed Inc. etc. to carry it as well. It should also be available from any Keystone Auto distribitor although it might take a little while for it to get into the Keystone system.

Regarding the LS2, yes, the TRG-001 will work for LS2 engine swaps into LS1/LS6 cars but it depends on which LS2 engine. LS2 engines with the 24x crank trigger wheel found in the 2005-2006 GTO, 2005 Corvette, 2005-2006 SSR, 2006 Trailblazer SS don't need the trigger conversion module since they already have the 24x crank trigger wheel and the 1x camshaft reluctor wheel. Later LS2 engines found in the 2006-2007 Corvette and the 2007-2009 Trailblazer SS do need the TRG-001.

The module will also work on early LS2 engine equipped vehicles (24x based) that want to upgrade to an LS3 or LS7 engine but in these applications you will need an extension harness for the camshaft sensor connector.
