Working model of a Chevy Camaro LS3 V8 engine.

Over 200 hours of printing!!! Engine block alone was 72 hours.

Modeled from cad files, pictures, specs, and service diagrams of the engine. I did not have the actual engine for this one.

It assembles just like the real thing!!!

Also the engine stand will be available for sale soon, if enough people are interested.

It fits my other engines too.

The electric motor that powers it is a 12V 500rpm geared motor.

Shaft Size : 15 x 6mm/0.6" x 0.24" (L*D)

Motor Body Length : 43mm/1.7";Motor Body Diameter : 33mm/1.3";Thread Diameter : 2.5mm/0.1"

The motor housing will need to be filed down slightly to fit the starter mount.
