Re: cleveland or windsor
Nope. You is wrong. The volume of the motor depends on the internals. Windsors came in 289, 302 and 351, and have been stroked to various other sizes. As have clevelands (although only 302 and 351 to start with I think).
The cylinder banks are closer together on a windsor. Clevelands are heavier which leads to an assumption that they are stronger (not sure about that though).
All modern Falcon V8's (EB on until the BA) are Windsors. Most being 302 (5.0 litre), although the T3 TS50 had a stroked engine.
Early Falcon V8's were windsors, and changed to Clevelands when they started making these in Geelong. I am not sure when the change over occured, but XA-XE are all clevelands. I think all the GT's were as well, although the XR's maybe not (as in XR Falcon in the 1960's, not XR8).
If this hasn't confused you enough, I am sure you can find heaps of info at GTFalcon.com and other sites with a search.
