Re: 67-68 Hi-perf Z28, L78 5 Blade/4 Rivet fan
My untouched 67 L78 June Norwood has this fan but with 3" clutch mounting bolt circle. Yes, I'm positive. Any known untouched 67, 68 L78 cars with 3 1/4" circle??

How accurate this this data??? http://www.camaros.org/coolingsystems.shtml [/ QUOTE ] This info is the same as stated in MacNeish's '67 Z/28 book for part number 3871276; I have the correct fan clutch and a 69 7 blade fan will fit the clutch as it has a 3.25in hole and a 3in hole fan will not work. Oh what fun the GM engineers must be having with our hobby....
