I did put 302 internals into my 289 block. You do have to use special pistons (TRW forged 302 short skirt flat tops with eyebrows in my case). I then used a stock 302 crank (turned .010/.010), stock rods, and high grade rod bolts. This (.030 over bore) made a 306 with a bottom end good for 300-400 HP @ 5500-6000 RPM. Works for me. N2O2 ?. I don't know.
