To the guy who started this thread, use Katech or Steve at R.E.D. for your block at a minimum. You can visit both sites by scrolling through the sponsors on your right. RED is Race Engine Development and Steve co-invented the LSX sleeves. Deffinatlly give the LS7 heads/intake a whirl as well.
MTI does good things, but there kinda pricey, and not as power effective as others.

As far as who ever told you that the LS7 intake manifold only makes 10-15hp more then a LS2 manifold is retarted. First, the two intake manifolds don't even fit on the same head, and secondly, when flowed, the LS7 head/intake combo STOCK flowed 330+cfm. Good luck getting even 280 out of the LS2 manifold.
As far as choking down 800-900, how about basically cutting even once you get the ls7 manifold (~300) and LS7 fuel rail (129) and i'm not even sure you need it, LS7 heads (2500) for a total of ~3,000 and you've got way more power then the stage 3 combo and are saving money at that.
I suggest that you do a lot more research before you dive into this!

since i have been doing the same research for several months im jumping in and saying that i agree with what is being said. LS2 427 + LS7 heads and intake all out of the box is the way to go. cost per hp is the most effective with this combo.

BUT the intake will cut flow back.
they flowed LS7 heads out of the box at 384 CFM
i wish i could afford the LS427 but just cant do it right now. LS2 403 is the route im taking for now.
also LME which is in houston is/was offering LS2 427 short blocks for $6199 no core, that is from a quote i got back in Feb.

That is true. $2999.99 no core. If you do have a core let me know and we can discuss an exchange price.
KATECH-i just saw someone from your shop at lapeer dragway w/a white camaro ss w/427ci claiming,was it 580hp to the wheels? the car was running between 12.2 and 12.4's that day. i tried to talk to the driver,get some info but he kinda blew me and a bud off(not good for buisness i must say)i'm in the market for a new larger ci motor.even know i thought the driver was a LITTLE rude,i still wouldn't mind talking with ya about maybe becoming a customer. was something wrong with the car that day? 580rwhp and only 12.2's doesnt seem on. did you guys get it dialed in?

I don't know who made the claim that it was 580hp to the wheels. Definitely not me because it had not been on the chassis dyno at that time yet. The car was running on 7 cylinders that day and it is currently on the chassis dyno trying to figure out why.
i didn't know you were the driver,i understand thanks. the 580hp claim came from the guys pitted by you at the track,thay said they knew you and saw the car on the dyno. that dont matter,i would like to talk with you on a motor for my car and see what we can come up with. i'm on a 346ci now and want more ci's for next spring. if you got time i'll call the shop. who do i ask for? thanks

Katech,
Some of these may be dumb questions, just want to make sure I'm not making any assumptions.
How much for the value 427 with ls7 pistons, heads, intake? Anything else I would need to change on my c6 to get this in there, like the TB, MAF or CAI? Whats the redline? Any tuning or install issues with a 2006 c6?
What cam options do I have with this package? I would like good driveability, but definitely looking for some lope.
Warranty?

CAI would be nice, TB and MAF can remain stock
7000
No issues. Just needs chassis dyno when it's done.
Good drivability and some lope - our Torquer LS7 cam. This will be like a wet sump LS7 and should make ~600hp, 570tq

I currently have a callaway honker, that good enough?
7000 redline, nice! Is it making good power all the way up to that point? I'm assuming I'll need good air and 42 lb injectors and a boost-a-pump for that.
then last question. What warranty do you offer on the engine?

We do not have an express written warranty.
How much for a 7 cylinder 427 engine with no warrantee? If I spent 10k on a 427 it had better be a presision instrument.
