They are listed for the 350 everywhere. Is that the same valve train as the 283/327 motors?
I went into the local NAPA today and looked them up under all of the inline six engines. and in the Mercruiser parts book for the 120 and 140, nothing. However, the NAPA guy pointed me toward and engine builder in Hermon, (70 miles away), and I called him. He said he had "all kinds of them". So I'll pick some up when my wife goes to the dentist in Bangor on Monday. Thanks for your help, I'll let you know how it works out.
