Jray,

I apologize for being a bit thick headed here but I still don't get this part...... Are you actually plumbing the heater feed into the "intake" as in intake manifold water crossover? Or do you mean the flow goes into the "intake" on the timing cover/pump housing? May be that a picture would help me here... I have a '72 model so it may be the difference in the design of the timing cover/pump housing for the '68 is hurting my small brain
I don't know for sure that routing this one way or the other is affecting the temps but every little hindrance to proper cooling system function will add up.....
Anyway, if you could post a picture of this I would appreciate it. I'm constantly trying to learn here.
