Jeff's 1973 Ford Ranchero GT
This 1973 Ford Ranchero GT, VIN 3A48Q197113 was originally a bright red, "Q-code" 351Cleveland-4V Cobra Jet/C6 car.
I repainted the car in March 2010, "Prophet Orange" in base/clear coat.
completed long block, ready for transmission

March 2012: 393 Clevland stroker: Bottom end: I used a 351C-2V block, 2 bolt mains with ARP studs, line-honed, decked & bored 0.030" over, 3.850" stroke cast steel Scat crank, Scat I-beam rods w/ARP bolts, Probe forged pistons w/lite weight, thin-wall cro-moly wrist pins, a Pioneer damper & B&M flexplate, all dynamically balanced; I installed a Moroso windage tray, a Melling stock volume oil pump with ARP cro-moly driveshaft, Melling oil tube pickup, and the oem stock 5 qt oil pan with home-made baffles; Moroso oil restrictors installed in main journals Cam: I'm currently running a custom Bullet hydraulic flat-tappet cam using lobe #HF277/335 with .580/.580" lift and 277/277' advertised duration (228'/228 @ 0.050"), 115' LSA, 47' overlap; I'm using mostly Comp Cams parts including Comp Ultra Pro Magnum 1.72:1 roller rockers, Comp #26918 Beehive springs with steel retainers & 7' locks, guideplates & 5/16" Comp pushrods and a Cloyes double roller timing chain set. Top End: I used Ford 4V iron closed chamber heads; I added stainless steel Manley 2.19 intake & 1.72 exhaust valves and a three-angle valve job, bronze quides, hardened exhaust seats, machined for guide plates & 7/16" studs, and teflon valve seals, and decked them enough to straighten them out.; I cleaned up the ports and the bowl area below the valves and around the valve guide boss, and installed them with Fel Pro gaskets and ARP head studs. Intake/Exhaust, etc: I installed an Edelbrock RPM AirGap dual plane intake and a Demon Speed 750 4 barrel with vaccum secondaries & a 13" open air cleaner; The exhaust manifolds are Hooker Comp headers, dumping into a 2 1/2" dual exhaust system with Magnaflow X-pipe and Magnaflow mufflers & exiting behind the rear wheels; I used a Ford single point distributor and installed a Pertronix III digital ignition module, then recurved it with new springs; a Pertronix hi-voltage coil, 7mm Motorcraft wires and Motorcraft #24 spark plugs round out the ignition system; All Fel Pro gaskets and ARP 12 point fasteners; stock Ford oem water pump and 60 amp Motorcraft alternator, a Motorcraft 600 CCA battery & a Powermaster Hi Torq starter. I tried to maintain the "stock look" with no clues as to what was hiding under those old valve covers...

Tech Inspection

Dragstrip photo, Sept 2009

My best drag strip time has been 14.5 @ 93 mph last summer; the car weighs 4300 pounds with me in it; I've just changed rear gear ratios (3.00 up to 3.70's), and the convertor stalls at 3500 rpm now with the new heads and headers, so these numbers should improve substantially.
My 60' times are pretty slow, 2.171; due to the small street radials (255/35-20) it's difficult to get off the line without smoking the tires.
