I would tend to agree. Using my Intakes as an example, we get the
following.
Stock 2bbl Iron intake: 42lbs
Aftermarker Alum intake: 15lbs
This yields us a 2.8:1 ratio.
I have a alum water pump on the way, once I get it, I will weight both and
let everyone know. The Alum block HAS to save more than 30lbs, that just
seems a bit on the low side now that I look at it. Probably means that the
iron block weighs more than 127lbs..
