Anybody know of a V8/V6 transplant or a convertible conversion HHR?
I wonder about making the 5.3l displacement on demand GP GXP and Imp SS motor and tranny to keep it FWD but get the V8 in there. Custom half shafts and mounts and such but that would be more easily done then the RWD alternative.
Not to mention all the electrical yada, yada.....
But the proof is there, the rwd v8 has been done. Im not convinced the fwd v8 version would fit.
It is interesting to hear of the development version with the 3.6 though. That engine does well even in a heavier camaro.

Look at all that room between the headers and the inner wells.

In this one you can see the rear end carrier they had to cut metal to make room for.

We sourced a prototype carbureted LS6 engine that was originally designed as a spec engine for a now-defunct circle-track series and decided it would make a great powerplant. Behind that we bolted up a heavily modified TH700R4 which ran to a 10-bolt rear out of a 4th-gen Z28. We modified and strengthened the HHR’s front suspension and added coil-overs and big brakes. Out back we modified a 4th-gen f-body control arm/torque arm setup to work in the HHR, of course adding better components and coil-overs for adjustability. In between the front and rear suspension we did a bunch of cutting and rewelding! We had creat our own trans and driveshaft tunnel, and build mounting points for the rear suspension. And just in case the 585-horses made by the LS6 wasn’t enough, we added a big NOS kit.
