If you want your motor to live, you'll need a stronger block, like an FMS block.
A good set of "worked" aluminum heads.....~$1100 for the heads, and I guess a couple hundred more for the work.
Some type of power adder (turbo, nitrous, supercharger)
A tranny that will live behind that power. I suppose a Tremec at minimum (~$1200) or maybe a T56 (~$3000 with all the conversion stuff).
Yeah, it's gonna take some cash. I left a lot out.
Good luck, though!
