engine parts

[ctx46]

Does any one know where a person can get alum pistons & rods for a 3.4 DOHC? Im going to be doing a performance rebuild next fall in my engins class and I want to start gathering parts...... oh yeah and roller lifters,

 

For those who are wondering I want to bore it 30 thousants over, new pistons, rods, re-grind cams, shave heads (to make a 10.5:1 compression ratio), turn crank & micro polish, thicker bearings, total seal rings, P&P on entire intake setup including heads.....

any other suggestions are more than welcome....
