    Hydraulic Lifter Tick

    I have a "H" code 351C in my 71 Mach1. There is a lifter tick with the cylinder #1 valves. I replaced the 2 lifters but the tick is still there. My thinking is to remove the 2 lifters one at a time and then prime the engine with a drill and distributor drive to flush out the oil passages. My...

    Finished rebuilding my 3speed 1972 manual shifter today.

    Today I finished rebuilding my 3 speed 1972 manual shifter. The bare metal was painted and all moving parts were packed with Mobil1 synthetic grease. This makes it better than new. I am using new shift rod studs and brass clutch rod bushings oh the Z bar from Auto Krafters in the rebuild ...

    Ford 351C & Boss 351: Engine Book

    Just bought a copy of the Ford 351C & Boss 351: Hot Rod Engine Book and Hi-Po Engine Series. It is a collection of all the Hot Rod 351c build-ups from 1970 to 1979. It is available on Amazon, a good read and the best $19.00 I spent in a while. It was copyrighted in 1991 with no reprints, so...

    2013 S197- The Other Underappreciated Mustang

    I think the S197 Mustang (2013-2014) V6 is the other underappreciated Mustang. For 2013 Ford added a lot of content to the V6 Base and optional Premium package. Here are a few bullets: Horsepower: 305 hp @ 6,500 rpm Torque: 280 lb-ft @ 4,250 rpm 30 MPG Highway 7000 RPM Redline Three Link rear...

    351C MLS Head Gasket Re-Torque

    When I re-torqued the MLS head gaskets after 100mi. on my "H" code 351, I noticed that the intake bolts (under the valve cover) were spot on and the exhaust bolts all required additional torque. This was the same on both heads. I assume this is due to the greater thermal cycle on the exhaust...

    Poor Man's Transmission Jack.

    I built a transmission adapter for my trolley jack out of scrap wood and an old jack pad. I also sawed off the head from 2 bolts to make guide pins for the Top Loader. This made the installation of my Top Loader manual trans an easy one man operation. Sometimes purpose made tools are the best...

    Mach 1 Fake Wood Exorcism

    After driving my 2013 MCA Premium Mustang with its beautiful black and aluminum retro interior, I drove my 1971 Mach 1. The fake wood deluxe interior suddenly looked like a 1980s throwback. I decided to go back to the standard black door panels, steering wheel inserts, and center dash bezel...

    Improved Motor Mounts for H Code 351C Engine

    The Prothane 6503 motor mounts are an improved captive design similar to the 1973 motor mounts. Prothane’s literature states that these mounts will not fit a 351C. This is not true, as they do fit the “H” code 351C engine with stock cast iron exhaust manifolds. I am using them on my 71 Mach 1...

    H Code Dual Exhaust Conversion Frame Bracket

    Thought this might be of interest. To the best of my knowledge, no one makes this bracket for the left side exhaust on 71-73 Mustangs. It was pretty easy to braze the bolts to the steel strap. The holes are already in the rear frame rail. You will have to fish the bracket into the frame rail...
