new some help on info on a v20

[aussie]

ok thanks guys for the big welcome
ok one guy said its a 6 and the rest said its a four
i was hoping it was a ford four half a big block
i am a mechanic by trade so if i buy it i intend to do some mods to the engine is the head on it the same as a 460 big block can one be used
what is the power like of the engine do they plain easy never had a inboard for that reason
for the price on the boat its a good price for a baot of its size over here and these boats r not seen here like me exporting a strange car to u guys the price would be high
well this guy has not been responding to my emails only one told me its a car engine that was alot of help
ok can u tell me if these engines vibrate alot dont like vibration
and can we say definite its a ford 4
