Unusual 70Z28 LT1 Fan Blade
 

1970 Camaro LEGENDS Judging manual and 1970 Camaro shows Fan Blade Assy 3947772 Fan Assy........as having SEVEN Blades..........

My 1970 07E Z28 (last week of production) has a non numbered, non dated (NO STAMPS) SEVEN blade blade that is different looking than the 772......

A Camaro Natl's 2nd Gen Judge has same fan blade assy on his 07E 70 Z28

Anyone reading seen this blade on another year, model of GM Car...........

Interesting!! Looks like a rare late ’70 Z28 variant. I haven’t seen that exact unnumbered 7-blade on other models, but it might be a late-production swap or leftover stock. My best guess

The fact that I (retired Camaro Natl's Judge) and a Current C Nationals judge both have 07E Norwood Z28's with this same fan blade makes me feel good about running the blade thru judging.....May never be explained as I think the 772 Blade is still shown in the 1971 Assy Manual......

Came on at least 1 1969 02C Baltimore built L78 Chevelle.


Henry did not think it was anything special.
Just the "plan B" type
