Re: 7 Blade Clutch Fan F/S

I will take it depending on the diameter. I need it for a 1972 SBC 4x4 truck.

Re: 7 Blade Clutch Fan F/S

I will have to pass. I need a smaller fan for the 4x4 shroud.

Re: 7 Blade Clutch Fan F/S

Newcomb is correct I use a PO box for USPS. Do you have any way to confirm it will bolt to a 67-72 fan clutch? If not could you post spacing dimensions for the bolt holes across from each other and the diameter of the center hole? I've got a spare clutch for a 72 that I'm going use in my 3100. I don't have a good fan for it.

Re: 7 Blade Clutch Fan F/S

It's always been my understanding that a GM clutch fan will mount to either a BBC or SBC clutch, no difference. This fan measures 2 1/4'' from bolt hole center to bolt hole center going from corner to corner. Measures 3 1/4'' hole center to hole center when measuring as in a diameter measurement ACROSS thru the large open hole. Hope that helps. Center hole of fan measures 2 5/8'' in diameter, forgot to include that.

I can confirm the BBC/SBC with my local parts store guru tomorrow. He KNOWS his parts, been in the parts business for nearly 35 plus years. fit

Re: 7 Blade Clutch Fan F/S

Spoke to my parts guy this afternoon and he confirmed; the fan WILL mount to either a SBC or a BBC water pump with no problem. Thanks for the interest, let me know.
