I am just finishing off putting a BB in my 69.
The fan shroud I have decodes as a SB shroud, does any on know what the differences are between big and small block fan shrouds
I don't know what the differences are, but I'm running a big block in my '69 and using the small block shroud and radiator. The small block hoses even work with a little trimming.
the shroud has to fit the radiator it doesnt care what engine is in the car. If you switch to a BB radiator you would need a matching shroud because of possible differences in the dimensions of the radiator core and positioning of inlet and outlet necks.

Thats interesting, the car was a BB, had a small block put in it, the radiator is a BB unit and was running a small block shroud....
So on that logic it should still fit.

don't know the difference between BB and SB fans but do know that the early models used a 5 blade fan and the later years used 7 blades. my 75 is supposed to use the 7 blade but has a 5 blade instead
