10s in an auto car with a 346 isn't hard.
4k converter
CNC'd or aftermarket heads
230ish cam
Fast intake
0 DA
Slicks/skinnies
Shift at 67/6800
Loose a little weight (k member, bumper supports)
Done. Similar for an M6 just need a bias ply and a nice clutch.

I highly recommend going with Advanced Induction. Phil over there really knows it stuff. A little bit of wait over the competitors but he'll spec a cam and CNC head package specific for your desires on your car. Track results back his work up so if you're looking for track times, he's the go-to guy.
As for weighing cars, go to a Rock/Gravel company. They usually have a scale for their big rigs. Just drive in and tell em what you're doing and say you'll recommend some people to go there for **** n giggles just to get on the scales. OR go to your local race track. Should have a scale there.

I get what u guys are saying. Ive seen the LS3 head debate go back and forth. Now I do know that if u put smaller intake valves in it will help to unshroud them from the cylinder wall. I was looking at the Mast black label medium bore heads. ANyone have any experience with these heads. I know these heads make some nice power on built ls3's but for some reason they dont make big power on 408-402ci motors. I cant seem to figure out why?

I dont really like that big of a valve in a 4" bore. There flow data is with a 4.070 bore...I don't know how much difference it would be on a 4". Your best bet would be to call MAST and see what they say.

I guess ill have to give them a call. Now ive always been curious as to why people say solid roller setups are "More Work". What kind of maintenance comes with using a solid roller setup.

With a solid roller you will have to periodically check your valve lash which I dont really think is a too big of a deal. I personally wouldn't run a solid roller setup without a nice set of shaft mount rockers though. I dont know the exact price off the top of my head but I think they start around $1100 and go up from there. Unless its an all out race setup I just dont think its needed or worth the cost.
