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?
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.

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