    Occasional smoke on start up.

    It sounds like they installed Viton valve seals, but they either need the top of the valve guides machined or have new guides installed. Even if the valve guides weren't replaced the Viton seals will seal with some looseness in the valve stems. It's possible one or more of the seals have slipped...

    Location location

    One word of caution, some electronic boxes can squeal or whine, and depending on the sensitivity of your hearing, can be annoying. Of course, a nice sounding exhaust will drown out the noise from the box. Or, if your hearing is like mine, I'd have to have 5 or 6 boxes squealing to hear them. My...

    Gas tank sending unit replacement

    +1, anything else added to it will likely peel off and wind up in the carburetor.

    73 q code vert competition suspension 9” posi rear - how do I tell 31 or 28 spline?

    If you have a Detroit TrueTrac it is much better than the original Ford TracLok. The TracLok uses clutches for the limited slip that don't have all that long of a life span. TrueTrac uses helical gears that last longer and provide better traction to both wheels.

    Heater Core Test

    I know how I would do it, but I have all kinds of pipe fittings, adapters, barbed hose fittings, and valve stems connected to pipe fittings. I would adapt and connect a valve stem to one heater hose, and plug the other one, pressurize the core to 15 psi and see if it holds pressure. If it does...

    Smoke on start up

    What kind of valve seals? Umbrellas or Viton positive stop seals? What kind of oil pump? A high volume/high pressure pump can send too much oil onto the valves and splash onto the stems and run down them with the umbrellas. The turkey pan gasket can be a PITA to get sealed, especially with an...

    Ford Code Numbers

    The CHR may be some option that is convertible specific. I couldn't find it in any of my references. If you have a Marti Report you might post it in the Marti Reports section of the forum, maybe we can find something in it that fits. https://7173mustangs.com/discussion-forum/marti-reports.59/...

    Intake Manifold Installation

    The intake manifold on the 351-C Ford engine is critical as far as torque rate and sequence are concerned. Intake leaks, although very slight, will affect engine performance and may result in oil burning. Apply the manifold with care, making sure it is aligned correctly, front to rear and side...
