With this price range for cast iron I'd rather rebuild my stock "prone to crack" ones. I'm was wondering are there any aluminium ones in that price range even if flow numbers would be worse then TF or Edel but better then stock.
I'm not trying to be cheap, but shipping and taxes will at least double the price for me :-(
