RPM intake is a great dual plane.

This has 6 degrees advance ground in, 112 LSA and better lift than the Comp. 270 intake duration is smallest with your compression but biggest with your 3.08 gears. DCR will be right for premium fuel. The 264 is out of the picture period. For a 383 with 3.08 gears, 4 speed, 400 HP target, RPM dual plane, 10 to 1 compression and 180 heads this is the exact cam I would put in it. I like a bigger cam but your gearing will make it soft on the bottom end if you decide to go that way. (see post #8) If your open to upgrading your gearing go the next size bigger on the cam and bump compression a little but your heads will restrict high rpm cylinder filling. JMHO.
Edit: Every build is based on a series of compromises. Matching everything in the build as good as you can within certain parameters nets the best end result.

So, a better plan would be new gears (3.23),a cam one step up from the 20120711 =(20120712), 10.5:1 cr and IK200 heads?

I would stick with your plan and existing budget with the Lunati. Easy on parts and your 400 + HP will be there. It is nice on a street car to make power in the RPM range you use and still get good fuel mileage. If your looking to go more radical the combo above would like 3.55 or lower gears but mileage and highway cruising comfort will be reduced. then your looking at higher rpm operation, foged internals would be best and od trans would help.Depends on what you want in the end.
