Yes, it has a car seat
Has anybody checked whether the block in the GTO is really the LS6 casting or the LS1?
Well, as far as power goes - it appears there is much in the way of aftermarket heads and cams that will make more than an LS6 setup - probably for less money. Again, like any mod question the question is what is your goal for the car?GTOWILL said:First off, please forgive my ignorance on this topic. I'm upgrade my B/R M6 with the best bolt-ons so as not to void my warranty (for now at least). However, an article (http://www.highperformancepontiac.com/features/0405pon_gtoautocross/) I read recently has me thinking about making some upgrades using GM Perofrmance parts. Since the GTO uses the LS6 block, what's everyone take on swapping the heads and cam for the LS6 counterparts? Would this void the warranty? Rumor has it that the '05 Autocross will have this configuration.
Be easy on me...I'm new to the group and the LS1 community.
Question - how did you manage to get to see this. I've dug around with the mirror back there for about 1/2 an hour and couldn't see any numbers on the back of the block. Is there a trick?JCMGTO said:Just looked on the back of my block, my casting number is "12561168" which by another thread means i have an LS6 block.
