A quick poll: The Plus 8 engine mounts are in 3 pieces, the top mount to the engine, the rubber bit in the middle and the cast bit to the chassis.
On your car, is the rubber mount bolted to the front of the chassis mount or bolted to its rear face?
Did the factory have a set position? I suspect most are mounted to the front but my ex race car is to the rear and wondered if this was a way of shifting weight rearwards a little.

Mine are definitely angled forwards.
As you have surmised most racers try to get the weight of the engine as far back in the chassis as possible. This will of course have changed the dimensions elsewhere on the car. Probably the most important will be the gearbox mountings and possibly prop shaft length.
When building a race car most series competitors (and almost all of those in Class A?) will start with a new chassis, and make the necessary modifications to it before starting to fit any drivetrain or body components. I suspect the gearbox mounting crossmember will have been moved back in the car a few cms, but it is also possible that the mountings have been extended from the original position (although I would think this unlikely)
One of Rob Wells race cars (ROB 8R) had the engine mounted so far back that I seem to remember that the gearbox change mechanism needed some modification so that it still fell to hand, but that is almost certainly a one-off.

Thanks Andy. Just to be clear are yours BOLTED to the forward face of the chassis bracket? Rather than to the rear as on mine?
Gearbox mount crossmember is original and in the correct place and I'm using a T5 box rather than the Getrag unit fitted, so gearbox mount and propshaft all have to change anyway.

Are you coming to the BHM breakfast meeting this Saturday , if so you can inspect my car (and others) there ?
Mine are definitely bolted through the chassis facing forwards.
