Replacement Fuel Injector LT-5
Halo everybody I'm going to refresh my LT5 engine so I replaced my coils with Msd
And I changed my fuel injector with I replaced the injector with 21 lbs But the table it shows me 21 lbs below 9.7 compression and the LT5 eng is 11.1 compression ratio. Which one is better for The LT5 is there any suggestions or recommended to go with ??? Sent from my iPhone using ZR-1 Net Registry Last edited by STATION; 04-27-2020 at 09:16 PM. |

My 378 mini stroker is at 12.5 and Accel 21 pounders are perfectly fine.

Re: Replacement Fuel Injector LT-5
I'm not the expert here, but don't forget you have two injectors per cylinder.

Re: Replacement Fuel Injector LT-5
Accel used to be a quality product. I read that their injectors are now made in China (??). Does it say on the packaging? If that matters to anyone.
I used to be a die hard MSD proponent myself. Used them many times since my first hot rod build in 1980. But now I read that they moved their coil & ignition production to China. Over the years I have had loads of problems with parts made or rebuilt in China. I do everything I can do to keep away from them. Does anyone know who makes coils for our cars that are made in USA? |

Re: Replacement Fuel Injector LT-5
I replaced my coils with AC Delco Professional Grade. Gold plated (corrosion proof) terminals. Don't know how the rest of the specs compare but they seem to work well.
