Hi, just letting yous all know I have just finished the block, and it turned out really well. I am very happy with it.
Rodger - I got some rust prime from super-cheap, water based green stuff made by septone and it worked really well. I will post up some pictures when the engine is finished, I will probably put one in this thread, but they will all be up in the thread of my car. I will post up the link here when the engine is in.

Thanks to all who gave input!!
