Way cooler. You can put a 3.4 v6 in an Opel without destroying the car, but any of the V8 conversions.....well lets just say thats why you dont see these cars around anymore. Putting in a V8 means chopping the car up, tube framing the front and making the front clip out of fiberglass. With all steel monocoque construction, mine is 53 years old and doesn’t have a squeak or rattle anywhere (except the poly suspension bushings)
I had a Dodge charger model that I fubared the paint on, but I kept the hemi engine. The Opel GT model had a V6 or 4cyl stock option, But I thought it would be fun to put the Hemi just for a neat model car display.
