A stock engine can make that power if you want it to and be just fine.
Small pulley like 2.8 or maybe smaller, big injectors and fuel pump and run E85. A powerlog and 3in downpipe for exhaust. I'm sure they still make headers but they were kinda blah all those years ago when I owned them. Then do a semi wild camshaft upgrade with valve train upgrade. That should get you a bunch of power.
If E85 wasn't something you could run you'd have to do an intercooler with meth injection to keep intake temps down.
