Also I see you suggested injectors, I'm really hoping to get away with the stock ls3's.. I know I'll be pushing them but I'd like to drive it this summer and that is an easier change down the road than internals, Also I'm only running a single in tank 255 6an feed and return and a vette regulator/ filter so Ill prob be close to the limits on the whole fuel side

And I've been told the 11.5-11.7 for comp may be too much for pump gas... Livernoise said the had the pistons custom made for that comp as I said I'd like to get the most on pump as I can, However in there specs they sent me they claim to use a off the shelf wisceo and we did our math and found I should be closer to 10.5-10.7 soooo don't know if livernoise slipped up or if they sent me the wrong piston specs

You need to know what the static compression is. Don't worry if it's high. You can get a custom cam to drop the dynamic compression as that is what really counts.
