Hi Guys

Probably been asked many times before but will replacing my standard GM injectors with Orange 19lb F**d items cause me any problems?

My 305 Tpi is stock

Any replys gratefully received

 

They will function just fine. The only problem is the ford injectors are rated at 37 psi, GM injectors are rated at 43 psi. This means that the ford injectors will actually be 7.8% richer than the GM injectors.
This may or may not cause you problems...

 

Thanks Ed,

What sort of problems do you mean though???

 

Might be rich at WOT, computer should be able to compensate during part throttle.

 

You get X amount of fuel with the stock injectors, putting in X amount more fuel over the top of what stock is expecting is going to cause an overall rich condition, not just at WOT.
