I have started work on full pressurizing B motor that will run insert bearing both main and rods have had the crank drilled good oil pump I am interested in what you guys do to improve the oil supply system do you close down to smaller the gallery the timing case open up the main bearing gallery s Colin
Colin, Only close the front hole in the galley when going to full pressure. The crank must be drilled to oil the rods. That front hole is there to feed the dipper tray. Other mods need to be made, I'll send you some more info.
