99+ stangs are NOT forged.
You can tell your uncle he is wrong.
Cobras have forged crank and the rest I'm not sure but GTs, definately not forged anything.
You can put a SC on stock internals no problems, all depends on boost #s. Of course there are plenty of people with 10lbs and maybe 12 or more on stock internals but I don't want to go that route.
8lbs on stock or 12-14 or so on forged if I can manage the $$ to get a kit and have my engine torn down. But now the stroker/big bore kits are out...
