Big block Ford engine bays are tight, and a full size distributor often will not clear a firewall or a tall intake. This small diameter Pro-Billet unit keeps the maintenance-free magnetic pickup and adjustable mechanical advance of the standard version in a smaller housing, and it ships with the cast iron gear these blocks require.

MSD 85773 Small Diameter Pro-Billet Distributor Features:

• Fits Ford 351C, 351M, 400, 429 and 460 engines.
• Must be used with a 6, 7 or 8 Series ignition control.
• CNC machined billet aluminum housing and base, black anodized with a black cap.
• Cast iron melonized QPQ coated gear installed.
• Polished QPQ coated steel shaft on a sealed ball bearing.
• Adjustable mechanical advance with supplied springs and stop bushings, and it can be locked out for crank trigger use.
• C.A.R.B. E.O. number D-40-39.
