im running the stock injectors(flow matched tho), 40lb/hr at 15 psi with a walbro 190 on a 305................would i notice anything if i put in a set of 55lb/hr truck injectors?

 

IMO, unless you are DIY tuning, you will probably do more harm than good because the ECM won't know you've increased the size of the injectors. The injector constant needs to be changed if you go to bigger injectors. 55# injectors would help if you are fuel limited with the stock injectors. You could push your current injectors up to ~20 psi to get more fuel, but again without tuning and datalogging, its hit or miss.

 

I've got GREAT NEWS, the stock 305 injectors (green/white) ARE 55 lb/hr.

 

is that right? huh, ok then, btw, im using a fpr from turbo city, cant get it to go any higher than 15...............maybe 15.5 sonmetimes as i have a fp gauge on dash

 

That's most likely because of the weak stock fuel pump, not the fpr.

The 40 lbs/hr injectors are from the V-6 TBIs.

 

if youd reread above, im using a walbro 190

 

...missed that
