Who makes a hemi-style head for a chevy small block, please post a link.
His block will support about 500hp, i don't know if i'd call 500hp weak though, that'll be plenty.
All his internals are already forged parts. His rotating assembly is balanced to within .25 of a gram.
As far as cast iron blocks being weak, i'm not entirely sure about that one. Nascar's use cast iron blocks and push like 750hp and rev out to like 9 grand.
Aluminum blocks are lighter, but still a casted block.
We recently met a guy that was running at least 500RWHP on his cast iron block, soon he hope to push 1200+ on that same block.
As far as that billet aluminum block, how do you have water jackets for cooling without casting the block? Mind power? :shrug:
