440 build ?? I'm gathering parts for my '06 GTO Daily/ Weekend driver
RHS Std. deck block 4.165 bore
Winberg 4.00 ccw crank polished
Callies Ultra I beam rods Shaftech Omni chrome finish
Diamond Pistons/ DLC coated wrist pins
Now I'm not sure which heads and intake to run. I'm not shooting for a specific HP rating, it's going to be what it is and I will be happy with it. Just would like to make it fairly reliable.
Would like to keep the compression around 11.5:1 range pump gas. Heads I'm thinking of Mast or maybe the new Brodix heads. Jesel lifters, Jesel rockers.
On the intake I'm not sure if I should go with a single round TB or double round or a since 4bbl type? Need to keep it DBW, so I guess that kinda makes my decision there. What are some of your guy's thoughts on this?

Also look at what you are going to do to control pressure under the cylinders. Increase to big block cubes in a small block configuration can be a problem. I was blowing out rear mains on a regular basis so I added the vacuum pump. It seems to be working.
MAST or TFS.... maybe AllPro heads. They all get the job done!
The MSD Atomic intake seems to be best one out for keeping things under the hood at a good price. If you go 4 barrel type TB that won't stay under the hood!

Can you elaborate on this, or know something good to read about this.
I have heard about the vacuum pump thing and know just enough
to make myself mad about it. But I don't have anything good to chew on.

A vacuum pump does just that, pulls a vacuum in the crankcase which when properly set up give you HP gains. Some things to consider is that if your engine is not set up correctly you can pull too much vacuum and pull oil away from wrist pins which can lead to problems.
Sealing up and engine is another issue for seals around the crank. Either way a vacuum pump is a great addition. Do a search online, there is plenty to read about how they work and what to do and what not to do.
I'm going to call today and see who has the best one for my configuration.

TFS LS7 HEADS (260 CC intake port) + MSD INTAKE having that combo MAMOFIED
with a Medium sized cam (235*ish intake with +12* Exhaust
Split, LSA 114*-115* ADV +2*-3*) would make 600+ RWHP
in a M6 application and drive like a total kitten at part throttle.
GZ Vacum Pump with no more than 10" Vacum should provide
Desired results without drying out wrist-pins with a well
Designed oil system.(ported medium volume pump is what
I would suggest) unless you are running 1 mile distances and
Beyond then you probably need a dry-sump.
Just my .02.
