Last Fall I decided to take my 70 Mach 1 that I had previously restored in 2005, and change the drive train. As with many projects this was going to be a small project of just converting from an automatic to a 5-speed, then an engine rebuild was on the list and then it quickly exploded to much more!! When I did the restoration in 2005, I only cleaned and detailed the drivetrain to make it look good and everything was done somewhat stock. (engine was non original and rebuilt by a PO).
All the cars I have done in the past have been to original, so this is a first for me going this far away from stock. The car will be 90% street and 10% track, with the goal of keeping it looking somewhat stock and still maintain my shaker.
Thanks to the many folks that answered my many many questions. I will start posting more pictures.
Yesterday we dynoed the engine so I figured I would start this thread with what has been done, and what is underway. If I went with a Vic Super or adding more than 1/4" spacer, we could have gotten more out of it, but I need to fit this under a stock hood if possible.
Engine:
Ford Racing Boss 351 Block, that is 460 ci, with Z heads
Victor Jr Intake, port matched/polished. Carb surface angle milled 0.3" front to 0" back
AED 950HOM carb, 1/4" spacer- (Fantastic Customer support)
MSD 85840 STEEL GEAR Distributor (clearanced/modified to work with intake, and black cover)
MSD Digital 6AL box, Blaster 2 coil (Will be painted to look more stock)
Vic Mechanical Fuel pump (sand blasted to look more stock and not chrome)
Holley pressure regulator with custom fabbed bracket behind carb allowing pump to carb fuel line on drivers side of carb.
Fuel pressure guage on regulator, and an additional electric one to be inside car.
Taylor Pro Spiral 8mm wires
All AN-8 fittings/hose and 1/2" SS lines from tank to carb. Aeromotive Prefilter with shutoff before pump, and another before carb.
FPA full length headers 1 3/4 pipes entire length- Some minor tweaks were required near steering box and idler arm. Still needed to be ceramic coated after final drive-line install.
Here is a link to the dyno video, only showing a few of the many runs done. This is a 12 hr day condense to 9 minutes.
Boss 460 Dyno Run - YouTube
Ended up at 550HP and 561lb.ft on pump gas with a very streetable engine.
13" Hg vac, so my power brakes will work.
Drive-line Continued:
Quicktime scattershield w/157 tooth flywheel
Hydraulic Clutch setup with slave from Modern Driveline
Clutch assembly: Heavy duty Kevlar/Kevlar disc rated to 650HP
Roller bearings on clutch pedal
TKO-600 - Modified with carbon fiber synchros, and top surface milled with low profile cover for more tunnel clearance-Modern Driveline
Mini Starter is TBD
Moser Center Section, 9 in. Ford, Nodular Iron, Detroit True-Trac, 31-Spline Axle, 3.70:1, 1350 yoke
Strange Alloy Axles with screw in studs, and sealed bearings that do not require axle seals
Driveshaft is still TBD
Leaf spring perches boxed in
Rear Suspension:
Calvert Split Mono-leafs, stock height
Caltracs- Low profile version given bumpy roads here and advice from Calvert racing.
Calvert Racing (Rancho) 9-way Adjustable Shocks
Global West Del-A-Lum Shackles
Front Suspension:- Stock looking
Opentracker Roller stuff: Track LCA's, and Drag UCA's with Roller perches
Roller Idler Arm, all new tie rods and adjusters
Street and Track Adjustable strut bars
Calvert 90/10 shocks for race only. Other shocks for street use TBD
While I am at it, replacing the rest of the steering components as well.
Chassis:
Shock towers have been reinforced on the inside and outside. Custom reinforcements on the inside, and the standard 45 degree plate on the outside.
Arning/Shelby 1" drop
Tinman subframe connectors, with an additional mounting points bolted into seat pan weld area with reinforcement plates inside.
Tinman driveshaft loop to be modified and installed later- Will bolt into subframe connectors that now have in welded nuts.
Export brace (1 piece)
Control Freak Engine cross brace tying LCA's to frame.
Other:
Ron Morris adjustable motor mounts- I can not lower the engine 1/2", but possibly 1/4" due to oil pan clearance. I looked at clearancing the oil pan, however, due to the stroke, and the less than 1/2" under the windage tray, no modifications are possible.
1/2" SS fuel line from tank-Prebent from Inline Tube to follow factory bends, compensating for larger line.
AN-8 fittings everywhere.
In line prefilter with shutoff making filter changes easier without taking a gas bath.
RobbMc 1/2" in tank sender with AN8 fittings factory installed.
SSB Front Disc brake slotted rotors. Stock style calipers for now.
Rear brakes, drum, with Porterfield R4S shoes
Hurst Roll control line lock
Street tires are BFG Radial TA's (yes they will not hook)
Slicks are TBD
Exhaust 3" TBD
Everything above is here or ordered and I am currently cleaning up the inside/outside of the engine bay and then can get going with reassembly hopefully in a week.
Here is a question. Given the HP of this engine, do you see anything that I have left out to properly support this?
More pics to be added to this thread.
