which engine do you think is more efficient and powerful the LS2 or the LS6 cause i was thinkin bout it and wondering if i wanted to do buy one. i know the LS2 are great engines but i didnt know too much bout the LS6 onlythat they came with the Intimidater camaro and old 454 chevelles.

 

The LS6 that came in the early chevelle 454 is a totaly different beast then the aluminum block 5.7 LS6 crate motor of today. http://www.gmperformanceparts.com/Pa...l.jsp?engine=2you can compare the data at their website and pick what you like more. I would have to say both are great.

 

ight thanks man
