The 1970 Ford Mustang Convertible was one of the lowest in production numbers. It is now becoming pretty rare. This one has spent almost its entire life (75,000) original miles in the western states. It was part of a west coast classic car collection and was then involved with another collector is a multi-classic car swap. We then got involved and purchased this Mustang. Most of this Mustang Convertible is still original and in excellent condition, such as the exterior and interior metal. Even both bumpers have original 1970 Ford markings on them and look like new. The carpet was removed floors cleaned and sound deadening material was installed then top end mass back black carpeting was installed. After we purchased it we went ahead and refreshed some of the interior and did some upgrades.
Also when we purchased this Mustang the upgraded Stroker 302 to 347 motor had already been installed as well as the rebuilt/shift kit C4 transmission with a 2,800 RPM stall converter. These pictures are taken over two years so there are some changes along the way. The plug wires are now blue, the tires are now BFGoodrich staggered size and other minor changes. Under the valve covers are spotless and like new SVO aluminum heads shine. The Global West sub-frame connectors are pictured along with the spray on sound deadening materiel beneath.
The previous owner did have it re-painted once using the same original Grabber Blue code. Following that they added the Boss tribute graphics. We had the extended the rear deck stripes painted to match the front. The previous owner had some further improvements done mainly building the Stroker 347 and C4 transmission. We have no paper work on previous work done only records on our expensive refinements and upgrades. Some of the additional listed modifications have been done to increase its eye appeal and muscle car performance and then others are focused on road handling.
The original 302 was totally rebuilt as a 347 Stroker motor. A very high performance 351 cam was installed and is revealed in the 351 firing order this motor now has. This cam helps in producing the fantastic rumbling sound and power of this motor. New Aluminum High Performance FORD Heads, SVO (Special Vehicle Operation) M-6049-X302 racing Motor Division were added in the build. An Edelbrock four barrel Aluminum intake has also been installed. On top is a very well built Holley 650 Double Pumper Mechanical Secondary Carb custom jetted with the correct power valve and a manual choke. Mallory ignition had been installed and it now sports new custom fit Blue Spark Plug Wires. Top end Aluminum cast valve covers continue to enhance the look. There are long tube ceramic headers flowing into 2 1/2 inch dual exhausts with a cross over pipe and new flow master mufflers. The warm idle vacuum runs around 8-10 inches as this is a mean built motor yet the power brakes still work fine.
The transmission is a strong C4 with a 2,800 RPM stall converter and has a good fast shifting kit and down shift cable providing very solid shifts. We just had the driveshaft checked over, tuned and balanced. The rear end has posi and it works.
Although the previous owner took good care of it trying to keep the car original in most of its appearance we decided to refresh certain areas. As mentioned we pulled the seats and all the carpet. I installed new sound deadening under lament then top end (Mass Back) black cut pile carpeting throughout. There are two sets of four piece floor mats, Blue Pony and deep plush BOSS 302. The drivers seat had a very small failure in the original seam so I had both seat rebuilt and fully recovered with identical OEM skins. The rear seat is still looking great and is original yet I also have a complete new cover if ever needed. We pulled the dash and installed Blue LED interior dash and courtesy lighting which look really sharp at night. All the gauges work correctly.
Underneath we replaced the original four stack leaf springs with new five leaf stacks, bushings and hangers. The front Ridetech variable rate springs improved the front. The Boss has a nice old school rake to it now. We upgraded the original front sway bar with a heavy duty 1-1/8 sway bar and hardware. Then we installed a new rear sway bar assembly as it never had a rear one. To increase the handling and strengthen the Mustang we installed/welded in Global West sub-frame stiffeners. This really took out any body flex improving the road handling of this classic even more. The front end got fresh hubs, wheel bearings, rotors, calipers and a new brake master cylinder. The entire car was aligned right into correct specs and drives with two fingers on the highway.
I also installed Hella lead glass headlights with H-4 130/90 watt bulbs all being powered by a H.D. relay kit. Then added two LED driving lights down low and out of sight in front and below the radiator to aid in night driving when using high beams. We also installed a new fuel tank and sending unit. There are two detailed lists in pictures of many parts. This Beautiful Boss Mustang Convertible is both dependable and runs like a well-bred race horse yearning for the open roads with its loud rumbling exhaust and its quick response to the riders will.
This beautiful Convertible Boss Mustang has provided a lot of pleasure and reward in both purchasing it and taking it even further in restoring and improving it. It now looks and handles like it should have been in the beginning. We enter it in all the regional Classic Car events and it always wins best of show also first and second places. I have lost count on the number of people who just walk up and start complimenting the Mustang to no end.
This beauty is available for inspection and a test drive as long as the weather is clear and dry. It is stored inside year round and only comes out is good weather and clean roads.
