| |
| {{Notice|text=Status: induction and displacement '''confirmed'''. Factory LPG status '''pending Marti deluxe report'''.}}
| |
|
| |
| === Displacement and configuration ===
| |
|
| |
| The engine is a '''Ford 429 (7.0L) V8, 4V induction, Lima-built'''. Confirmed by three independent on-vehicle sources:
| |
|
| |
| * Air cleaner lid stamping: {{code|429 4V LIMA ENGINE}}
| |
| * Valve cover tag: {{code|E7AE-9C485-CGG}} / {{code|7.0L HFMO7.5AGEI}}
| |
| * Intake manifold casting: {{code|9425-DA}} (prefix obscured by coolant hose)
| |
|
| |
| The {{code|E7AE}} prefix dates the valve cover to the 1987 engineering year, consistent with the October 1987 chassis build date. The engine is believed original to the chassis.
| |
|
| |
| === Induction hardware ===
| |
|
| |
| * Mixer: '''Impco CA425''' — 4-barrel-flange mixer, correct for a stock 4V 429.
| |
| * Mount: cast-style, no obvious aftermarket adapter plate. Photographed for the record.
| |
| * Fuel: LPG. Believed factory or ship-through conversion; see [[#Fuel system status|Fuel system status]].

| |
|
| |
| '''Believed factory LPG — pending Marti deluxe confirmation.'''
| |
|
| |
| Supporting evidence:
| |
| * Cast-style mixer mount with no obvious aftermarket plate
| |
| * DSO special order tag ({{code|DSO 74 / SO 3152}}) on firewall
| |
| * Factory fleet options: built-in traction sanders, front tow hooks
| |
|
| |
| On confirmation, upgrade to fact and cite the Marti invoice line. If the invoice shows a ship-through or upfitter conversion, log as "factory-ordered LPG conversion."
| |
|
| |
| === Blower build notes ===
| |
|
| |
| * Single Model E vaporizer is '''insufficient''' for boosted volume — plan on '''dual Model E vaporizers, boost-referenced''', parallel coolant feed, equal-length reference lines from a common manifold source, and a lockoff sized for combined flow.
| |
| * Single CA425 mixer is '''insufficient''' at target power — plan on dual mixers into a common plenum with a fabricated dual-plate adapter.
| |
| * Compression and cam to be measured by the shop before boost selection; do not assume gasoline-spec figures.
| |
| * Heads to be checked for LPG-spec hardened seats at teardown.
