So... For Michael and any other crazies out there that might be considering something like this... here is what my cooling system consists of.... its very similar to what i ran very successfully for ~ 3years, but now even more simple and now effective after shifting the cylinder head steam lines to the water pump's hot side..
RED - cylinder head steam lines (1/4" heater hose):
OE-type hard lines that tie the heads together, one on the front end, one on the rear.
"T" at the rear high point with a 1/4" NPT bleed valve, coming off the rear steam line.
"T" at the front to tie the front and rear together.
3/8" NPT to hose barb to tie line into hot side of water pump.
1/2" NPT plug for cold side of water pump.
WATERPUMP:
OE-type corvette style pump.
heater hose bungs removed - crush them in a vice and pound an awl/screwdriver between the housing and mangled bung, twist and remove. Drill and tap for NPT.
