I have to make a decision soon on what block to run and am looking for some input. Heads-up hemi, 65 belvedere trying to push the 1100 mark. I know the iron block will make more power, but it weighs a lot more as well. Is there anyone out there putting Worlds new block on a cnc diet? If so, any ideas on how light they can get? The one I saw weighed like 350lbs

There's no wheelie bars allowed so weight on the nose might not be a bad thing. I do like the repairability of alum and the light weight, so it makes for a tough decision on what way to go.

Thanks in advance for any help
