The short answer is Yes.  The engine = mount I=20 build is called an S-beam

(Schertz Beam) mount.  The concept was = first=20 developed by Bill Schertz

and was modified by Paul Lamar and others = until it=20 evolved into the

present configuration.  The S-beam = mount only=20 supports the front of the

engine.  The rear engine support is = provided by a=20 adjustable  strut

that runs  from "someplace" on the back = of the=20 engine to "someplace" on

the firewall.  

 

I guess = which is=20 the =93front=94 of the engine is a relative term.  I conclude it = primarily=20 supports the flywheel end. It appears structurally very sound, but I = wonder=20 why there are struts along the engine bulkhead between the support=20 points.  Those would only be needed if the bulkhead (or structure = between=20 the attach points) was not structurally sound.
