Well, i got another heatercore today, so thats a bonus - its half inch barbed, and a better design with more fins, so hopefully it'll be more efficient. Cleared it out with the new pump I also got today, 800lph, 1.6m head pump. total cost of pump and rad was 65nzd, 40US or 27ish BP.
This is the design I ended up going with -

And this is a rather bad scan of the first run at drilling it. My very cheap 100NZD drill press did NOT like this much, I can tell you
its definately a budget drill.

Well, I should have everything else set up shortly, should be interesting to see how it performs. And yes, i was in a hurry
ill be dremeling the gaps tomorrow, next time i do it (if this block performs well) i'll be making sure im a bit more accurate.
