Joe Strunk,
Is your intake aluminum or Magnesium? Air gap with a valley pan or solid? Open or restrictor plate? Ford made a new one every week for NASCAR so there are many versions of the Spyder single 4v. Some are XE, XH, C9, even Holman & Moody. Hard to put a value on them. Kind of a beauty is in the eye of the beholder thing. Send me a pic and I will try to ballpark a value for you. They you can try EBAY or Boss302.com and find more potential buyers. 703-929-4955 or
rapidmustang@aol.com Any other Boss 429 parts let me know please.
Bernie
