I remember reading somewhere the difference in weight between an aluminum head, water pump and housing, intake big block VS. a cast iron small block. Does anyone have this info. I remember reading it was within 5 lbs. of the small block.



No but here's a bump for you as this has always been an interesting question that nobody seems to be able to answer definatively.

I suspect that you could easily get a big block down to less than the weight of a stock small block using lightweight internals, aluminum heads, intake and waterpump housing, lightweight starter, headers, etc.

Of course there are those that will say "sure but the small block will still be lighter if you do the same things to it" but that kinda misses the point plus the weight gap would narrow as they got lighter.
