[blue87lx]

im swapping in a 351 w victor jr heads and intake.. what size injectors should i use and fuel pump? will also have a zex 125 shot. will the factory computer work with the 351?

Stock computer will work. Upgrade the pump in the tank to a 255lph. And add an external pump if needed.

Get a tune when as well.

30 or even 36lb injecotrs would do

I have a question also about this subject. A friend of mine is replacing his 5.0 with a 351w.

Can you use the stock 5.0 computer and injectors on a stock non-HO 351w?

Is the firing order etc. the same, meaning can I take the distributor out of the 5.0 and put it it directly in the 351?

Thanks...Brad

No you have to use a 351w distributor

Everything else will work, or would injectors be the only other thing that needed changed?

Knowing the lower intake will have to be changed.

I'm asking on the fuel/intake system only, we know the other stuff that needs changed, just not sure about the fuel system.

TTT. I know this is kinda old but I would like to know the same info with a speed density and 19 pound injectors. Im sure it will go TTB but it worth a try.

blue87lx:
EFI 351 W swap:
You need 351 EFI distributor,
minimum of 24 LB injectors.
MAF calibrated for injectors,
351 W EFI lower manifold.
Minimum of 155 LPH fuel pump (use a 255 LPH if NO2 or forced induction is in the future).
Stock computer: the 351 W and HO 5.0 use the same firing order. The stock A9L or A9P will work fine.

Send me your email address & I will send you the 351W swap sticky that was posted here several months ago.

NIKLID05:
Don't try and use a Speed Density computer or 19 LB injectors on a 351W. The results will not be satisfactory.
