Exactly. If all you are concerned about is going fast in a straight line and no creature comforts BIG BLOCK!
You can make 500hp with a stock short block 460 and bolt ons. If your savy and and lucky at the swaps and E-bay you can make way more than that for alot less than it will cost you to get it out of a 4.6
I was making 750hp with a stroked 429 and I did for less than 8K
Big Blocks make WAY more torgue with ease, that's whats gonna get you that low 60 foot time
Stock shortblock ,stock heads ,stock cams.
