Time to start the build... insight plz!

Hey guys,
Well im new to the mustang scene, but not new to mechanics by anymeans.

What exactly is the stock 302 block (roller motor), capable of handling without the block itself failing. This will be a street driven car, but i would like to see somewhere around mid 10second quarters with some wheels-up torque.

How do you guys feel about a 347 mated with a t-trim vortech? What are some companies to steer towards, and what are some to stay away from.....

Like i said, my goals are a street brawler, that (while i know suspension and tying the body together is a huge component, as much as tires are), id like to see it lift the front end skyward. What exactly am i getting myself into? Thanks guys,
Chris

Thanks for all the serious responses guys. I come from an import background, and its good to see a forum that isnt full of a bunch of punks. while im 'only' 19 myself, Ive done nothing but bent wrenches for a living for the past 5 years, so im pretty comftable.

As for buying a pre-assembled block...id rather build me own. its a pride thing.

I must say though, im a bit depressed with these stock blocks being limited to 500hp. I know i gotta watch my mouth, but thats just unimpressive, and quite frankly, upsetting to me. Im a B18C1 nut, and these 4 cyl blocks are so boost friendly, that it is not uncommon to see then hit the 600whp mark on a stock block (with forged internals, and heavily boosted, as to be expected, but with a unmolested block itself)

So lets take the to the other end of the spectrum. How do you guys feel about the 460? This car will be street driven, but its a straight-line performance mindset here. The foxbody just doesnt handle like my GSR did, nor my MR2, plain and simple, and never will. It turns like crap, and brakes like crap, even with being lowered, tower bars, and slotted rotors. Its milestones above a stock fox, but coming from my background, ive come to terms that this will be a straightline car, and im ok with slowing down for the corners (gettin old ya know )

Anyway, what are the opinions on the 460 swap? Im looking for something that i can build right away, with somewhere around a 5-8000$ pricetag as of right now, and then indefinately upgrade until i either get bored of the build and move on, or finally become content (yeah right!). Im a big fan of forced induction, so thats something to keep in mind....I dont have a preference as to carb or efi, but as much as ive gathered (im still a little green to the domestic scene. work with me!) that it seems carb'd is almost a more cost-effective way to go for big numbers. streetability in my opinion needs to be something i can drive 40miles on the weekend without it breaking. Thanks again for all the help guys. Its appreciated.
