Last month on America's most overheated car...
No fan shroud, car got real hot down the road, and overheats when I hit
highway speeds. It is a fresh rebuilt '68 Pontiac 400, I have a new radiator
(now 2nd), water pump (3rd), and I'm on the 3rd thermostat.
Decided to take it on the highway. As soon as I hit 4th gear, a small
explosion and sparks greeted me with radiator fluid and smoke pouring out
the end. Found my water pump (2nd one) had sheared off and cut my new $$$$
radiator to pieces.
The suggestion was to get a fan shroud. I did.
Same thing now, except my newest water pump has held all the way to 2000
RPM. Yeah, I'm actually scared to take it any higher. The gauge goes to 250
(rally gauges) and at 35-40 Mph I get 3/4 to Max on the gauge.
Could it be my timing? I have it set at 12 degrees, but when timing by
sound, it ran better way out towards (I'm guessing) 30 + degrees. It has a
street/strip cam, don't ask for numbers, it would take a month to find it in
all the paperwork.
I'm trying the timing, and if it doesn't work, either take a gallon of $3.65
gas and end its evil hold over me, or pay someone to haul it to the crusher,
(It really is an evil car, I have stories), or park it for another 10 years
for another poor sap to sink $$$ into it.
Please help or send priest for an exorcism
