Did I say that?

No, the chassis should be ok for the Rover engine.

The bit about the pinto and the Rover V8 being the same weight is a bit of an urban myth, probably the fault of the internet.

The rover block weighs a little less than a pinto engine, which means that the dressed V8 is 25kg or so heavier than the pinto. It's still a light engine for it's power.

The V8 gets lighter and the pinto gets heavier everytime I hear this yarn, to the point that someone told me that the Rover engine was "about two thirds of the weight of a pinto" yes it's got a lighter block but a huge crankshaft, 8 pistons and 8 con rods do weigh something!
