The engine is a Ford very high performance 390 with 0 miles on it since assembly and was developed for uses in a "66" Ford Fairlane Pro Street Car that would be raced about 50% of the time and drive on the streets for cruz nights the other half of time and was constructed with a cam and compression ratio of 10:5 to run on "91" pump gas. The block was stress relieved and all casting flash removed. The block was them "mag" for cracks and blueprinted buy index decking off the center line of the crank. The block was then index bored and honed 0.30 over this mains caps torque on the block and a torque plate install on the head surface. Then the blocked was then line honed with Caps and torque plate install to stress the block the same as when the heads are installed. The block oil gullies were drilled and enlarged based on the advice provided in "Dove's" book on "FE" block prep and a Milodon high volume oil pump was installed. The crank is a standard 390 unit turned 0.10 under on both rods and mains and then mico polished to provide a .00015 oil clearance with normal bearing crush. Once all the parts were ready, the entire rotating assembly was "bob-weight balanced. We used a flex plate that I had and they zero balance it first. If you plan on running a four speed set-up, you'll need to balance your flywheel and clutch to zero balance, if its going to be a automatic you'll need to have your flex plate zero balanced. We used "Clevite 77 bearings throughout the entire engine along with "Fel-Pro gaskets. The rods are standard 428 units with ARP "wave" bolts pre torque and then the big end re-sized. New bushings were installed in the small end and rods honed to provide a clearance of .0015 on the pins. The piston's are forged TRW units cut to provide a 10.5 compression ratio and were installed with "Childs& Alberts Z gap rings" The heads were install with the Fel-Pro head gasket recommend by the head manufature,"Edelbrock" . The new heads are "Edelbrock Performer RPM for Ford 390-428CJ. Combustion chamber size is 72cc. The spring have been changed by Edelbrock to allow for more than 600in lift cam (these heads currently list for $1,249.00 in the "Summit Catalog). The heads are toped off with adjustable FE rocker arms and a set of special and rare aluminum Le Mans Cobra tall valve covers for high lift cams. The oil pan is a after market aluminum unit which holds 8 quart and is a knock off of the old Cobra T-Pan. The camshaft is a "Dove" design for street/strip use and is ground and shipped by "Comp Cams" for "Dove". It is a sold lifter grind with numbers of about 238/248 @ 050 lift. Max lift is about 625 based on a 110 center line and was installed 3 degrees advanced with a "Comp Cam" double roller timing chain and ARP bolts used on chain and stock harmonic balancer. The most interesting item with this package is the intake system. This is a Ford factory option C8AX-9424-A 2X4 "tunnel wedge intake" with matching BJ-BK Holley's Carbs with all of the factory linkage and 2X4 air cleaner. It also has the factory "S" shaped breather/oil fill at the back of the intake. These were originally offered by Ford as a special order on 406 and 427 Fairlanes and Galaxy and as a Ford over the counter race item. This same unit was used on Factory Sponsored "68" Mustangs with "428"CJ's and on "64 Thunder Bolt Fairlanes. The unit is just sitting on the motor for the photos and is not installed because you may want to bead blast before installing. The carbs are all there but will need to be gone-through. I had planed to start-up and brake-in the engine with a single carb manifold to make things simpler than install this piece for summer cruz nights. This is the second engine that I have developed using this combination. I have a friend also running a "66" Fairlane with some heads and cam. With a Performer RPM intake and a 750cfm Berry Grant carb the car runs low 11's with a 10in. tire in a 3,600 pound car will all glass and was driven to the track. He makes his shift's at 6K, and the car runs strong and is a ball to drive and the cam is small enough to allow nice manners on the street and big enough to still be pulling at 6K. The car has a noticeable lump at idle which is heard more than felt when you drive it and it's right on the edge where you want to take it out of gear at a stop light. The motor is "dry" with only assembly lube (no oil) and you should be sure to primed the motor before fired it off for the first time. I am asking $6500.00 for this motor email me for pics. The motor is located in houston, Texas
