Love My A Bodies But I

Found an old English Fibreglass body Called A Reliant SCIMITAR you may need to google, I have three A body Australian , and my dilema is I have a pretty wild 440, that wont get much street use if I transplant it into on of my A bodies , So I figure Big Cubes Fiberglass Body 1000Lbs Lighter probably more like 500lbs when I kick the Ford V6 out , Gas is so expensive here in New Zealand that a Big block is not practical for long trips , instead I will use a S/B for street trips Cruises , I have heard of a Couple of Scimitars running V8s back in the late 60s But cannot find any info on them Your Thought would be appreciated as Thanx
