Their a harley Davidson injector as well

Kehein was also an injectors used, but I believe predominately on the small block. RC Injection in Torrance, CA has Kehein style if that is what you need. You would be best off with a matched set. I've been using their 42 lb injector for the last 6-7 years with good luck. They are flow tested and matched to within .5% (1/2 percent).
