ACME Engine Replicas: 426 HEMI vs COPO 427 vs 454 LS6

Published by

ACME 1:18 426 HEMI engine and transmission display replica, accessory only

Choose the 426 HEMI for a Mopar engine display, the COPO 427 for the Camaro subject, or the 454 LS6 for the Chevelle SS connection. These ACME 1:18 offers are standalone engine-and-transmission replicas. The complete vehicles shown or named for reference are not included.

426 HEMI: A1806139E

The 426 HEMI engine and transmission is identified with the 1970 HEMI Cuda subject. Its approximate dimensions are 4 inches long, 1.75 wide and 2 high, and the engine is described as wired and plumbed.

Choose it when the HEMI itself is what you want to display. A separate engine can remain visible beside a car without relying on the view through an open hood. The listing does not establish an additional workshop bench, engine crane or matching display base.

COPO 427: A1805736E

The COPO 427 engine and transmission identifies the 1969 Camaro subject and is listed at approximately 3.5 by 1.75 by 1.5 inches. Wiring and plumbing are stated details here as well.

This is the focused choice for a COPO-oriented display. For the complete vehicle instead, select the A1805736 Camaro without the E suffix. Similar product names do not mean the accessory and car contain the same objects.

454 LS6: A1805530E

The 454 LS6 engine and transmission identifies the 1970 Chevelle SS subject. It is listed at approximately 3.625 inches long, 1.625 wide and 1.75 high, with wiring and plumbing.

Choose it for that Chevrolet engine identity rather than treating every large Chevrolet replica as the same 427 or 454. The numerical engine designation and item code both help keep a mechanical collection accurately labeled.

Compare the footprint, not a horsepower score

The HEMI listing is the longest and tallest of these three accessory offers. That can matter for a small shelf or a display beside a model car. The dimensions describe the complete engine-and-transmission replica, not only an engine block or the size of an unopened package.

This is a comparison of miniature subjects and dimensions, not a claim about real-car performance. Wiring and plumbing are display details; these replicas are not operating automotive engines.

Is installation in a car guaranteed?

No drop-in compatibility is established by these listings. The wording identifying a donor subject does not publish mounting-point spacing, clearance, attachment hardware or an installation procedure. Confirm those details before buying an engine for a custom-car conversion.

For a standalone display, choose the engine family and footprint you want. For a complete car, check that the offer is not an E-suffix accessory. Review current price and availability in the Acme Models & Collectibles collection.
