Re: fuel injector id

this may be a eureka moment, they will be insufficient to properly feed a 350 i assume? it stutters and backfires when you wack the throttle open

Well, possibly yes when you consider that 305 injectors are 2x 55 lb/hr and truck 350 injectors are 2x 61 lb/hr. You can try bumping up fuel pressure as a stop gap measure.
