383 or 440 Dilema

This decision could also be affected by what aussie A body is it going into and the legalities of engineering it . A 383 may be legal out here for engineering purposes but a 440 may not be. This can sometimes favour a 383 or 400 being used (can always stroke it and they wouldn't know).

The formula is 5 x weight in kgs (on registration papers) for engineering purposes.

Eg

Would have to weigh 1442kgs or more to be legal with a 440

or

1255 kgs or more with a 383

My VC valiant early a body 66 model weighs 1350 kgs on the papers so I couldn't legal engineer a 440 into it and get it registered.
