I've been weighing parts, and they are not as heavy as people think. If you use the aluminum parts available they can get pretty light. Nothing cheap about them, but you do not need a lot of aftermarket parts.
X2 Dosen't take much to wake them up . My 354 was 40 over good cam and scored some Chrysler heads that had been bowl hogged . It made 450 HP.
If I would have kept it , I would have opted for Hot Heads aluminum heads. That would have lightened it up a bunch.
