ACME Truck Engine Replicas: LS3 vs Small-Block 350

Choose ACME A1807222E for the LS3 engine subject associated with the 1967 C10 Custom, or A1807223E for the small-block 350 associated with the 1967 K10. Both are 1:18 engine-and-transmission display replicas, not complete pickup trucks.

LS3: A1807222E

The LS3 replica explicitly identifies the C10 Custom as its associated vehicle subject. Its listed dimensions are approximately 3.25 inches long, 1.75 wide and 1.875 high.

Choose it when your miniature engine collection or garage scene is intended to feature an LS3. The combination of a 1967 truck name and a Custom designation describes the model subject; it should not be read as a claim that this engine was factory-original equipment in every 1967 Chevrolet truck.

The description lists wiring and plumbing and excludes the pictured vehicle. It does not establish a supplied workbench, hoist or separate engine stand.

Small-block 350: A1807223E

The 350 engine and transmission replica is associated with the K10 subject. It is listed at approximately 3.25 inches long, 1.5 wide and 2 high, with wiring and plumbing.

It is the more direct choice for someone specifically seeking a small-block 350 display. Sharing a Chevrolet truck connection does not make it the same engine as the LS3 accessory.

What the dimensions tell you

The two accessories have the same approximate listed length, but the LS3 is wider and the 350 taller in the catalog measurements. A shallow display compartment therefore needs more checking than a length comparison alone.

Those measurements cover the advertised engine-and-transmission objects. They are not mounting-point measurements, and they should not be treated as precision dimensions for a replacement-engine installation.

Display use versus a custom-car conversion

For a stationary garage scene, pick the engine identity that makes sense beside your other models and leave enough room to see the detail from the intended viewing angle. Any bench or stand needs a stable support surface sized for the actual replica.

For installation inside a model truck, confirm the available engine-bay space, attachment locations and transmission clearance before ordering. The phrase from a named truck does not establish that the accessory will fit every release of that truck or a different brand's body.

No working drivetrain, powered operation or complete conversion kit is promised. Wiring and plumbing here refer to miniature detail.

Check the E suffix

A1807222E and A1807223E are the two engine-only codes. Do not assume a similarly numbered wheel set or a complete vehicle contains the same parts. Select the exact accessory and review its current availability in the ACME collection at Muncle Mikes.
