Phil listed what a similar engine would cost to build. Your results may vary from mine because I supplied some parts from previous builds and used parts you may not need.
A similar custom carb through ProSystems is about $900. They have better options available now which I may switch to in the future. They now sell a billet setup called the EV1 which is worth 10-15hp over their custom Holley setups.
If you want a similar engine, I would call Ai for a quote. Different heads, valve train, or internals can greatly change the price.

Nice setup, but I am into more the real world high HP DDs, 13.1cr and e85 or 108 is not real world use to me, but please don't think I am knocking the setup, it's nasty 
But with that said, I guess I am to assume that a PUMP GAS 12:1 can't make 700+? I ask because I am building a 425CI/L92
Thanks!

Regarding 700hp, yes, we can certainly do that on 93 octane in a drivable EFI configuration, with better low rpm power.
Jim, our current programs are based on the GM 821 LS3 and GM 823 L92 castings. We'll release more of our aftermarket casting based heads this winter whenever we can find the time. However, whether cathedral or raised rectangular port, we often manage #'s with GM castings comparable to what is often done with the aftermarket castings.
Thanks guys!

Started the engine in the car for the first time last night!
The peak timing on E85 was 29/30 on those runs. I think I've got a bit more power in this engine when I can do some track tuning later this month.
We'll see what the engine wants with this 105 octane E85.

Jim, I knew when I left them out that it'd likely be one of the first questions. The reason we often don't share the specs is that in our experience they are of little use aside from often fostering misconceptions. You cannot accurately judge a camshaft by the common .050/lift/lsa specs typically posted. It is similar to attempting to divine something useful about a cylinder head by reported flow #'s. Ultimately there are many grinds we could run that would make essentially the same #'s, but with different characteristics and compromises. For instance, a 23Xdeg LSK, or 24Xdeg XER grind could be used to make similar #'s. The cam that is ideal for Sean's 700hp 416 may not be ideal for another guy's 700hp 416 application. So, not to disregard your legit question or to be sarcastic, but "big enough to manage 700hp, small enough to drive well and peak below 7k with a large single plane and head, and mild enough to control to ~8k."

You are right, you cant judge a cam by just the lift, lsa, etc but you can judge a whole engine package when there is information out there like you have provided that gives dyno runs, graphs, and the breakdown of all parts used (including the cam), so people can make choices that way. If cam #'s didnt mean ****, then you could delete about half the threads on this damn site for real.
Tireburnin, glad you are happy with ur engine combo, AI knows how to move some serious air thru an engine, now lets see some 300shot/7k shift runs!
