Hey all, I have a SBC in my 85 ext cab. The engine placement is far enough forward that it got into the radiator on it's first trail run. I've picked up a new rad (22" tru cool from speedway) and I'm planning on putting it in the back with a turaus fan. I'm trying to figure out the plumbing now. I figure I'll need an electric aux pump to help things along.

I've read around and have decided to price out both copper and hrew, but I'm wondering what size. I've seen suggestions going from 1" to 2". I'll be running rubber hoses up from the pipes to/from the block and the rad in the back, So I assume I'll be able to compensate for the different hose sizes there.

What diameter should I run the tubes down the frame?
