|}

=== 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</code>
* Valve cover tag: <code>E7AE-9C485-CGG</code> / <code>7.0L HFMO7.5AGEI</code>
* Intake manifold casting: <code>9425-DA</code> (prefix obscured by coolant hose)

The <code>E7AE</code> 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]].

=== Intake casting ===

=== 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</code>) 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.

=== Documentation ===

Photos filed: air cleaner lid, valve cover tag, intake casting, mixer and mount, engine bay overall.
