I have a SBC 377, I have just taken it apart because it was pumping oil out the # three cylinder. It has a bad oil ring, cylinder walls are in good shape. I was told the rods were Lunati and the pistons were JE, but the rods look stock to me and the pistons I'm not sure. The pistons are dome pistons and are 40 over. All it needs is new rings and bearings. before I tore the motor down the oil pressure was 55-60 PSI at 1000 RPM's. I also have the heads that was on it they are the old DART/World of Products Heads. I have roller rockers and poly locks and stud girdles for them also. Will sell everything listed for $1200.00 OBO. the only reason I am not going to use it is I don't think it is enough for a Late Model.
