LS3 build -OR- LS2 build
LS3 build -OR- LS2 build Trying to decide which would be the better route to go. The blocks are very close in price and the internals would be nearly identicle as well. I can get more CI out of the LS3 which is nice. I would use a 4.1" stoke to get 427CI out of it as opposed to the 402CI out of the LS2 block. The motor will stay N/A. I do however want to stick with the aluminum block because I want to keep the weight down.
Are the conversions the same between the LS2 and the LS3? The motor will be going into a 2002 Camaro Z. I would just like to hit around 500 to 550 to the wheels with a healthy torque curve. It will just be a street cruiser that I take out on the weekends.
Like to hear your opinions guys!
Thanks

We have a fully sleeved, machined, honed, balanced and blueprinted 427package that starts at 5500.00 and you could bore it on out to 4.165 if you wanted to go even bigger. I can do high compression or low compression pistons. You can get on our website and look at our different packages and if you have any questions about them just ask me. This package is a sleeved block and will hold much more power than stock sleeves will.

LS3 (4.07) block, with a 4.00 crank = 418. That's a good combination.
Your 427 with a 4.1 has a stroke bigger than the bore. That may not be the best way to go. There are probably a lot of people here that could prove me wrong, but that is a big crank to be swinging. I would rather keep the weight of the internals down with a smaller stroke. That will rev fast.

This is just a question but wouldn't the extra stroke provide more torque?

Like 99BlancoSS said with the 4.100 LS3 that we do the rotating assembly is lighter (than a 6.125 rod 418 and we do both a lot) since we use a longer rod and a much lighter piston but .050 more arm isn;t going to really change much anyway. 418 works well too though.
