Hi all i have a gm goodwrench 350 in my 89 t/A. I curently have 305 injectors in my engine. Ive been told 305 injectors work better with a fuel regulater because 305 have better optimisation of fuel when the fuel regulator is put up to about 50psi.I was thinking about getting accel#24lbs injectors for my car.My 350 is preety much stock except for headers. What would be better for my car the #19lbs or #24lbs injectors?I have a fuel regulator on my car to.Im thinking i could get a little more power with #24lbs injectors, but i could be wrong. Any info would be appriacted thx.

 

I just put Accel 24lb/hr in my stock L98. I can't complain about their performance at all. You have the added benefit of the adjustable fuel pressure regulator as well. I would think they would go very well with your engine.

 

I myself, would leave the 305 injectors and bump up the fuel pressure.

In most cases, when adding 24lb injectors with a stock chip...you're basically just dumping fuel into your cylinders. If you do decide to get the 24lbers, make sure you get a custom chip burnt specifically for those size injectors.

 

If you plan to leave the 350 "pretty much stock", get a set of 22Lb/h injectors and set the pressure to 43PSI for optimum performance. Injectors are designed to operate efficiently within a given pressure range and on/off time constant. Too much pressure, harder work to open. To little pressure, poor spray patern. Do the math, 305 to 350 and 19 to 22 rounds off to 1.15 increase. Virtually no changes will be required for the ECM from 305 to 350.
