I'd just really question your heads/cam with builder. Runner size gets brought up from time to time and opinions vary on builds. Nothing wrong with that and makes good discussion if results are what you aim for. Sometimes we just don't all get there the same way. It almost seems it's gonna be cammed for x rpm and heads size for X rpm. Just don't wanna lose velocity. Sure you don't want to go tunnel ram?

Just having a cup of coffee playing with the Pipemax program.
606ci turning 6500RPM, making 900HP.
Recommended valve lift = MIN .786 Normal .885 Max 975
Required intake flow 381-404 CFM at .874 valve lift
Required exhaust flow 275-298 CFM at .948 valve lift
Carb CFM 1175-1440
Recommended cylinder head Cross sectional area 3.523 (A 357cc AFR has 3.435 min csa for reference)
Headers for low to midrange power
2.10 to 2.225 " Primary ID 32.4 to 35.6 inches long
Midrange to upper rpm power
2.30 to 2.425" Primary ID 32.4 to 35.6 inches long
Collector diameter
4.051 to 4.301 best for tq
4.301 to 4.801 best for HP
Not sure a set of Gils or E Tops would work well on this monster, or a "741" cam

Here you go. Check out website and take it for what it's worth. Can't remember if shafiroff has been brought up on OSO or not. After a quick search I didn't find anything shady but it's a website and it's the interenet. Lol..
598/1,000-1075 hp

We are using them in the 665 build this year - we made 949 hp - 936 tq. easily could have been over 1000 hp but we restricted ourselves to the cam selection plus offering very well mannered idle speeds, MAX rpm around the 6200 range and pump gas of 91 octane. The engine runs like a swiss watch even at idle plus acceleration is very strong.
With ING1A coils you have to watch out what you buy because there is knockoffs being sold as well.
alot of the build is posted up here. The bottom end is built to handle 2000 hp. Custom Hilborn. We are running 10 widebands as well for a jist of it.

custom hand made wiring harnesses. The ECM is a MS3 Pro
We tried the Ultimate first but had firmware issues. We also had the MS3 Pro on hand as a back up. We kind of knew beforehand about the issues with Ultimate. They were brand new to market when we received our Ultimate so of course, not much validated out in the field testing and usage was done with the brand new version. IMO too much of a rush push to get it out in the market.
