Have a look at the CPUI fan or case fan on youe computer....
u will notive that the tips od the fan blades are as close to the shroud part as possible...
This stops air spillage off the ends of the blades, dramatically increasing fan effiency
To me your pic looks wrong...there seems to be a huge gap between the fan blade ends and the shround????...is that the right shroud/fan combo???
Also check the radiator cap is good and at least 13lb (std is 15lb I think)
I have a 1969 Camaro with a 327 that I recently got back on the road. The motor was rebuilt a few years ago,
Did u get the headers on the radiator removed and cores manually cleaned....
This should be std proceedure as is new oil pump/water pump is when rebuilding a new engine.
But as I continue driving with some stops, it eventually gets up to around 210.
When one stops, there is no water moving, or very little, the heat of the engine heats the water faster hence the higher reading, then when one is moving again the temp drops...this is normal.
The first time it got to 210, the radiator overflowed some, but that hasn't happened since.
This is normal when the raditor is over full
