The NCRS judging manual states the fan blade assembly for all big blocks with or without A/C is part number 3888366 with 5 blades attached to each enter reinforcement with 5 flat head rivets per blade. I've been searching for an original or reproduction fan blade for my 1967 427/400HP with A/C. However, several of the websites I've seen advertise for this part number state it's only for 427s without A/C. Is there any difference between a big block fan blade without A/C and one with A/C?
Thanks,
Brian
