| '''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</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 ===

|-

|-
| Prefix || Obscured — partially read, ambiguous
|-
| Location || Top surface, rear of carb pad
|-
| Status || 4V confirmed; prefix to be re-read at teardown
|}

=== 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.

| '''Status''' || VIN, GVWR, and wheelbase '''confirmed and cross-checked'''. Trans and axle codes '''pending chart decode'''.
|}

=== VIN ===

<code>1FDXB70K4JVA01204</code>

Decode:

{| class="wikitable"
|-
! Position !! Value !! Meaning
|-
| 1FD || USA / Ford / incomplete vehicle (chassis cab)
|-
| X || Restraint / GVWR class code
|-
| B70 || Chassis series — medium-duty
|-
| K || Engine code — 429
|-
| 4 || Check digit
|-
| J || Model year — 1988
|-
| V || Assembly plant — Kentucky Truck Plant (Louisville)
|-
| A01204 || Sequential production number
|}

'''Title and insurance must read 1988 and match the VIN exactly.''' The incomplete-vehicle build date is October 1987; the body is March 1988. Title as an 88.

=== GVWR and weights ===

{| class="wikitable"
|-
! Field !! Value
|-
| GVWR || 28,000 lb
|-
| GAWR front || 9,000 lb — 265/75R22.5, 22.5x7.5 rims, 120 psi cold, single
|-
| GAWR rear || 19,220 lb — 265/75R22.5, 22.5x7.5 rims, 110 psi cold, dual
|}

Front and rear GAWR sum to 28,220 lb; GVWR is set 220 lb below the axle sum. Rear axle is a heavy full-floating medium-duty unit — good margin for the blower plan.

'''Check:''' confirm current tires are rated for 120 psi cold front. A lower load-range tire makes the label pressure wrong and over-tires the steer axle.

=== Buck tag ===

Firewall-mounted, adjacent to VIN and DSO tag. Ford format ("Vehicle manufactured by Ford Motor Company, Made in USA").

{| class="wikitable"
|-
! Field !! Value
|-
| Wheelbase || <code>275</code> (275 in)
|-
| Type-GVW || <code>B70280</code> (B70 series, 280 = 28,000 lb class)
|-
| Body || <code>7</code>
|-
| Trans || <code>AA</code> — '''pending decode'''
|-
| Axle || <code>2MN</code> — '''pending decode'''
|-
| DSO || ''blank — DSO on separate tag''
|}

'''VIN on buck tag matches jamb label exactly.''' Verified character for character.

=== DSO tag ===

Firewall-mounted. Partially illegible.

{| class="wikitable"
|-
! Field !! Value
|-
| DSO || <code>74</code>
|-
| Special order || <code>3152</code>
|-
| Remainder || Illegible — not scrubbed, preserved as-is
|}

A DSO tag carrying a special order number is physical proof of a fleet special order. Match against the Marti invoice when it arrives.

=== Fleet special-order options ===

* Built-in traction sanders (hopper and dispenser — photograph mounting and frame attachment)
* Front tow hooks (factory option on B-series; photograph brackets)

Both point to a municipal or district fleet order, consistent with factory LPG.

=== Open items ===

* <code>AA</code> trans code — '''must resolve before the shop quotes'''. Build assumes C6; do not let a quote rest on that assumption.
* <code>2MN</code> axle code — ratio drives cruise rpm at 28,000 lb and blower gearing. Check for a ratio tag on a differential cover bolt or the housing.
* Both resolve via the Marti deluxe report.
