71 bb shroud question
folks, 1st question, is small block and big block shroud the same? 2nd, I have seen metal and plastic on ebay for same year, can I assume it should be metal only? (71 454)

Hi a,
During 71 production 454 equipped cars had a plastic shroud while a simple round steel fan shroud was used on 350 cu.in. cars which have an aluminum radiator.

A later car with a 454 engine and a plastic shroud.
A 71 with a steel shroud and aluminum radiator.

Hi PK,
I believe that for 70-72 production:
Only base motor, 4-speed cars had the steel shroud.
Base motor automatic, or base motor a/c, or base motor automatic and a/c cars, had a copper radiator and the plastic shroud.
All 454 cars regardless of transmission or a/c used a copper radiator and plastic shroud.

Alan

Just wanted to mention that 454's with a/c uses the 7 blade pointy finger fan blade along with the plastic shroud. Non a/c uses the 5 blade fan blade.
