My new Dart Little-M stroker is almost finished and I'm at point where I need to make a final determination on the restrictors.
The people at Dart told me this about the Little-M priority main oiling and restrictors. They said, "if you're using a standard oil pump, don't run the restrictors." "But, if you're running a high-volume pump, use the restrictors."
I have a HV Moroso billet oil pump, so I currently have restrictors installed per Dart's advice. However, my plan is to use the oil primer shaft with a drill and carefully watch how-much oil is moving to the top of the engine through the lifer bores. Then based on too-little or the right amount of oil top side, I'll decide whether or not to leave, or remove the restrictors.
Also, the lifer bores have been honed in my new block and the lifters (Howards Pro-Max) feel very smooth in the bores.
So, what do you think about my plan? i.e., make a decission on the restrictors based on what I see with the top side oiling with the primer.
