Cast iron vs alum block?
So, looks like I'll need to source a new block after very heating mine badly at the last race.
I am having a hard time sourcing a good clean used alum block, but found a few good deals on a cast iron block. Essentially the same engine, reusing all my original internals. The cast if block is about 80# heavier, but should be more stable and reliable. Thoughts on whether the weight is wrth the added reliablity ?
