Ring lands separated yet on this motor?... 
The A&A kit will stave off detonation, but 700-800whp on stock rods and pistons is a ticking device (pardon the pun).
Toughest in the gang, but damn it's catastrophic when they come unglued..
Keep us posted! No shame - your customer asked for more! He'll eventually learn what we all do in this racing game...

750rw with a D1sc and mine did this even with changing the oil every 1500 miles (wasnt my daily). When the motor let go we all thought a ground wire let loose because there was no "boom", the car just shut off.. But you aren't kidding, when these motors let go its catastrophic.

Well, this build just took a turn towards the WILD side!!! Work is in motion and plans have been set to build a forged 377 cubic inch LS3 short block utilizing the existing Advanced Induction CNC ported 280cc LS3 heads, stock LS3 intake manifold and a new camshaft designed to be as stealthy as possible while doing everything it can to help push this car over 1000rwhp on blower alone.
We will be using Wiseco pistons, Callies H-beam or possibly Ultra I beam rods, stock crank, ARP main studs along with the existing ARP head studs and around 9.6:1-9.8:1 static compression.
Another new addition to this build will be a 60mm waste gate that we will be using for boost control. Rich(the customer) wants(and needs) boost by gear and the only way to do that is with either a AMS 1000 or a Hyperkontrol boost controller via a waste gate. This will be a really cool feature to have if not for the fact that having boost control on a super charged car not being cool enough. We're going to pulley the YSi very aggressively so that we have total control of every drop of boost we plan on putting through the new motor.
Did I mention that this will all be done and accomplished on 93 octane pump gas? Of course we will be utilizing the dual nozzle snow methanol kit that is currently installed on the car. IIRC there are currently 7 lbs./hr nozzles in each nozzle and those will need to be doubled at the very least to 15lbs./hr.
Stay tuned for even BIGGER horsepower numbers!

The shop owners, or cam guys that tell you that overlap is good for a supercharged motor, don't understand what overlap is and how it really works other than it makes the car sound great at idle.

Well that escalated quickly. Did he decide on RHS for sure? If not the ERL superdecks are pretty stout and matched with some Mast medium bore 6 bolt heads that thing will **** and get. Well it will either way. I think I missed it but does it have the a&a stage 1 or 2 fuel system?

The way we look at the ERL stuff is we can get an aftermarket block, with priority main oiling and a slew of other features that aren't incorporated in the ERL Superdeck stuff. Could ERL probably do all that stuff for us? I'm sure that they could, but it's a no brainer when the RHS block is pretty much ready to go other than machine work.
If we go 6 bolt, the heads will probably be from All-Pro.

Any plans to get rid of that fuel system? If so depending on what I have going on I might be interested. I totally get it but like to mention different things just incase. All-Pro's are so damn nice. Futral had some mounted on a RHS block and man that setup looks to be no to be seen all of the time.

Of course! It will have at the most 2-4 degrees of valve overlap. It will be extremely stealthy. I've found that with superchargers, valve overlap is not beneficial. Especially with a LS3 cylinder head like is on the car now. It's a very efficient high flowing port that doesn't need as much overlap as a smaller less efficient port. With the pressure differential that exists only in a supercharged engine overlap is critical in not over scavenging the motor.
The shop owners, or cam guys that tell you that overlap is good for a supercharged motor, don't understand what overlap is and how it really works other than it makes the car sound great at idle.

Soooooo is it true you will be shooting for a 1,000HP on stock cubes?!

maybe stock cubes...I cant remember...my friend that helped me drop off my car said "It's unbelieveable the kind of power those LS motors make". He's thinking of putting a bung in his header(s) for a wideband on his next motor to see about dynoing his racecar
