Re: heater water plumbing

A: It has a valve outside the firewall and I've seen the hotwater return 
line go to the intake on the back of the driver's side, then it comes back 
out at the front and down into the waterpump. If you plumb them so they are 
parallel then the intake may get too warm and vaporlock?

So I bought a 1983 "TSM" for my motor (258), but it's practically
worthless.  A flimsy thing with the bare facts and no useful
photos! What crap!

Can anyone give me hints on how the water gets plumbed? Is the
heater core full-flow? How does the intake manifold get plumbed?

My plan is to find some "Y"'s and plumb the heater and intake in
parallel. The 1970 heater has the cable-driven hot water valve.
Did 83 use a hot water valve or was the core full-flow?

I use "Y"s in my LP car, since the water-heated LP converter needs

water heating. I figured I'd do the same here.
