i was told by people that owned my truck that they put 75HP marine injectors and i cant seem to find any information on them does anyone know anything

 

Should be the ones ending in 854 or 864. They should be 4 hole 155*. Not the cleanest and will not allow for timing above 16.5*

some 5x.012 with the correct spray pattern will run cleaner and cooler without any loss in power.

 

i know these runs run warm and smoke a lot at cruise with a hazy

 

5x0.012 sac injectors would be better and then have your timing set to 17* or 18*, you would probability get better fuel mileage as well.
