Default New truck, checking my build idea

I just picked up a 93 W250, 5-speed and am planning my build. Its a daily driver that does some towing. Although I want power, I want low end, quick spooling off the line torque. Screw high hp dyno pulls, this is a VE pump. Im planning on an exhaust manifold and a super b type, or a 62/65/12, that will eventualy be part of a set of twins. Injectors, I was thinking of the CPP 7x.010's. Then the typical pump tuning, a 366 spring, M&H #3 fuel pin and dynamic timing advance. Then a 4 or 5 inch straight exhaust. Would this be a good combo? Any advice? Oh yea, gauges are a given, and will be on before any mods.

After the first of the year, I will be going to twins, PS intercooler, NV5600 swap, cam, headstuds, o-ring & work head, whatever else I can figure out.

may want bigger sticks if you are planning for twins 7x.010's would be great for the superb or 62/65/12

What would you recomend that would not be too much for the single, but would be more appropriate for the twins? 7x.012?

7x.010's will work but you will want more. 5x.012's work well with my super B but with twins i would want 5x.014's

Dont the 7 hole injectors work better on the low end? I think I want to stick with a 7 hole if I can. Isnt a 7x.012 going to flow alot more fuel than a 5x.012?

a 7x.01 is small than a 5x.012

and i havent really heard any conclusive data about 7 hole being any better. everyone i know runs 5 hole from street trucks to pullers.

Then I will have to look at a 7x.011. I have talked to a couple people who run them and they all claim slightly quicker spooling and right off idle grunt. Even if its miniscule, any little down low, I want. I havent heard of any problems or I might look into 5 hole.

I forgot to mention, but I do plan to do a low pressure piston lift pump swap.

I'm not a fan of CPP especially for injectors. Have had some problems with quality control issues, on time shipment of product, as well as general communication and customer service. I know some people receive good service from Jamie but he dos not seem to be the most reliable source for injectors.
