What size coolant hoses?
I have the trans cooler lines/fittings/adapters as well as the Kool tool kit, assembly lube etc. I figured I'd better do this in stages or I'm going to lose track of what I planned on for adapters.

Thanks to everyone for their help. My mind was a bit boggled with visions of fittings and adapters dancing in my head. I spent the last few days searching for options to go AN for coolant hoses and kinda drawing a blank. One of the guys on a LS site said he uses 16 (top) and 12 (bottom) but that equates to 1"and 3/4". He has a stock LS but I still can't believe he's not having cooling issues because the factory outlet in the LS is 1 1/2" (top) and 1 1/4" (bottom) which equates to -24AN and -20AN. I'm not finding much in the way of -24AN hose or fittings. I'm concidering 20 (1 1/4") and 16 (1"). What do you guys use on small/big blocks? They're 1 3/4" and 1 1/2" correct? If you have or we're going to use AN hose what size would you use n a small/big block? I really want to match all of the other hoses and hard work I'm going to be putting into them. I installed the flex stainless corregated stuff from Speedway and I just don't like them.
To couple these I'm going to use the male weld bungs from ARP. On the pump I'll remove the stainless top outlet which is press fit in, cover the hole with a blank piece of aluminum, and move the AN bung to the top eliminating my space issue between the electric fan and the pump. Not much room. As far as the thermostat (which is on the bottom of pump), a couple places make AN housings. Then weld the appropriate bungs on the radiator. I'm loving my TIG by the way!
Thanks,
