Ok 42 it is then unless there are further objections?

What engine modifications do you have?

How can we tell you are actually going to run 400 HP at the engine?

30 lb injectors will be just fine for 400 HP at the engine, N/A.

Stoke 302 to 347, Trickflow perf kit, MAF, Cold Air, Exaust, Etc, and maybe a supercharger down the road, and it will be tuned.

Did noone read the stickies??? I posted a link. Use the calculator

copied straight outta the link i posted:
Here is a good formula to find out what size injectors you need
(H*B) / (C*D)= estimated injector size

H=horsepower (Rear wheel)
B=*B.S.F.C. (see below)***
C=number of cylinders
D=duty cycle (constant .80-.85)

B.S.F.C.=
Low to med. performance = .50
Performance engine with head work= .45
High performance with lots of head work= .40-.45
S/C or T/C engines= .55-.60

So, according to the calculator, you would need 28.125 injectors, or 30#. If you plan on supercharging dont even waste your time with the 30's, and step up to AT LEAST 42's. But at that point the best fuel system in the world isnt gonna keep your block from splitting down the middle

I dont think I will supercharge anyway. It was just a thought. Soo, id be safe with the 30# injectors then with a little extra. Objections?

42# you will want more power anyway. and 30# are going to be in a major duty cycle with 400hp
