Mark, he said in a previous post that he was going to run 2 13Bs. A Defiant iirc. Gordon, the distribution of power is about the same for the rotary with a bit higher exhaust portion. Properly ducted about 2-3 cubic inches of heat exchanger still applies.

Bill,

I don't think Gordon is running a rotary, so the 2/3 - 1/3 rule
probably doesn't apply.  I have no idea what the water-oil ratio of is
for a 4.3L Chevy V-6, but I'd bet that info is available somewhere on
the internet.
