LS2 vs. LS6

[thegman]

I have an opportunity to pick up an LS2 or and LS6 for the same price. What are the pro's and cons to each? I plan on working either of them to get north of 450hp. Any input is appreciated.

Get the LS2 - bigger bore = more head options.

As for 450 FWHP (if that's what you meant) with a good cam and headers you'd be hard pressed NOT to make 450 FWHP.

450 RWHP is harder, but by no means difficult (although it may shorten valve train life).

More cubic inches every time!

Starting from scratch I'd pick the increased cubes.

Plus the LS2 computer system is better.
