I have a 65 b body street car with a 71 340 in it .
For the last couple of years the engine temp seems to be getting higher and coming up more quickly and if left to idle will boil over.
Over the road the temp will drop to 150-170ish..
I have replaced the stat, the coolant , the water pump , have checked the timing , changed the cap .
It makes and holds pressure .

I plan on changing the stat again as I have had terrible results from stant stuff lately. Been having good results with MR G stats.
I was going to pull the radiator and see if I can flush it .
There is no shroud and I will put one on.
There is no fan clutch and would like to put one on.

Questions.
Are all 22" small block shrouds the same ? It has a parts store radiator that has the tabs for the shroud . If I had to guess I would say its a duster 340 radiator .

Best source for a reasonably priced shroud ?
for a driver ?

Does anyone know the brand and # of the shallowest clutch ? I have seen it posted from time to time but never jot it down
Thanks
