does size matter???

For my car i'm going to go with a 427" stroked/bored 351 for the simple fact that with a large cam it'll idle better than a smaller engine, i'll have enough power to kill most vehicles, and although gas mileage won't exist it'll have plenty of torque so i won't ever have to change gears uphill and i'll make it a mid range engine so i don't have to wrap the holy hell out of it or boost the crap out of it, which hopefully will make for a very long lasting engine. If i had a choice between a BOSS 302 engine or a mild 460 i'd have to go with the 302 for the simple fact that they sound wicked and epitomize the muscle car era, but that would be very expensive and for me the 427 is a relatively cheap long lasting choice and i'll never wish for more torque because i'll already have too much....i don't even remember what i was getting at, oh well.
