Which Injectors?
 

This winter I will be assembling a new stroker motor for my 87 5.0. My setup is going to be a 347 stroker, twisted wedge heads, 1.6 roller rockers,edlebrock performer intake,x-303 cam, and the usual bolt ons. I'm doing a mass air conversion also. This is my question. What size injectors do I need to support his setup? I was thinking 80mm sensor with 30lbs injectors and a 255lph fuel pump? Any input would be helpful.

30 or 36 should work..

The combo you have in mind sounds good, shouldn't need to go any larger as long as you're staying n/a.

Agreed, 30's sound good for that combo.
