If it's your first car and your primary driver, you might wanna leave the 302 in for gas mileage sake... Cause if you're paying for your gas you're gonna suffer with a 351 or bigger.
A 351 can provide more than enough power for a street car, IMO. I would only use a big block if I were gonna drag race the thing... Not to mention they're a bit heavier than small blocks, so I would imagine the car wouldn't handle nearly as well with a 460 in it as opposed to a 302.

Are you doing your own mechanical work? If you have to pay a shop to do the work the it's gonna cost you plenty to swap to a different engine [:@]
& don't underestimate how much power you can squeeze out of a modified 302! Not to mention the small block is gonna be lighter than a 460 like FendrBendr said

RE: help wit a motor
You can get it out of a 302, but I hope you're going to do some serious research as to what you're going to need to do to get a 9 second car.
I mean, you're going to spend WAY more in mods than what you paid for the car and the car won't drive much like stock anymore. It'll also have a full roll cage and just about every major component in the car will need to be replaced or compeltely re-built with high performance parts. Engine, transmission, drive train, suspension, fuel system, etc. etc.
All that will cost a lot, especially if you want it to stay street legal. Easier and cheaper if it's going to be a trailer car, but still expensive.
Either way, I'd strongly recommend you do some searches in the forums and look at a lot of the signatures of the people on here with serious drag cars. A lot of people list their mods, times and HP numbers in their sigs. that will give you an idea of what you're looking at.
If you just post up a "how do I make a 9 second car?" post, most likely noone is going to take you serious and/or give you any meaningful replies.

I think it is a 331 maybe? They mostly come in trucks/suvs but if you bought one and put on a set of Cobra heads and a blower it would be a powerfull motor that would get better MPG than a pushrod motor
