Engine size difference v8

hello

on my previous thread i . was talking about a 3.5 or 3.9 v8. It was the carb version that i saw turbo'd but anyway is the 3.5 and 3.9 the same size and they are just bored out larger? . As you will likely no it is fairly tight underneth the bonnet. atleast for the spark plugs .

replays would be welcome

regards

exactly the same but 3.5 bored out an extra 200 thou to fit wider 3.9 liner ,4 litre 4.6 ,4.2 and 3.9 same size bore different strokes
