 I just met a girl a few weeks ago, and asked her the same question. She looked a bit offended. But I really wasnt sure (and I had to know the answer). 
 
anyway, i liked Barry's post on a 427??? crank in a 390 FE. Being pretty ignorant of engine details, can anyone tell me, bragging rights apart:
 are there any issues with this? special pistons needed??
Does it need a particular cam? 
how does this handle compared to say a 390 overbored to, say, 406? 
Im guessing it improves the torque considerably as well as hp? 
what is the upgrade cost compared to an FE390/406?
Finally, and I hate to mention it, (but at >$8 a gallon in the UK, its important)
how much would it drop the mpg going from 406 to 427? 
- realise this is dependent on the juice pedal, but using say similar driving style, %-age wise.
any comments appreciated, particularly if you have one of these specs.
cheers,
Kevin
