That's ok, I wasn't sure if my price was out of line or not. I'm curious to know also what some minor differences may be.

Rick's pricing is in line with the market. I just bought one for the same price, which is high but what decent parts aren't? the difference in this fan and other 5 blade, 4 rivets is: a 3.25in bolt pattern vs. 3in normal; a 2 5/8" diameter fan clutch hole. These blades were used due to higher rpm on the Zs and L78s.

The vet is 3 1/4 also is it not??? I am not sure on the center hole dia. The vet one on the auction also confirmed
3 1/4 once it was taken apart??. Still not seeing it maybe it is just me

Good question, I don't know anything about vette fans, just what I read about these fans and that they were only used on camaro z28 abd L78. I know these are a specific part number, would have to go check, so what part number is the vette? Would GM have two diff part numbers for same part depending on vehicle???

Unfortunately I have no books to check the vet part number for the fan may be someone else can assist there. I do know the vet used the same DG water pump pulley as the 67/68 Z 3770245 since I just sold a NOS one to a vet guy for his small block and he was real interested for me to search through my fans.
Also I think we had a 68 l-72 and a regular 68 396 350 hp with this fan (3871276). I remember looking for a replacement clutch unit for the 396 and the replacement ones would not fit the fan blade but the one off the 68 l-72 worked.
We don't need 3000 dollar fans currently running on or put away for old 68 BB , if that is possible.

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??

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....

According to my car, not very accurate. Maybe the mech lifter cars were supposed to get the 276 3.25 bolt circle fan - mine got the 562 3" bolt circle.

OK I need help from the 67/68 Z-28 crew since I am still not clear on this 3871276 fan.
Today I got a few minutes to dig a little into my fan pile and found some of these as I thought I would.
5 blade, 4 rivets, front marked "front" with a "H" opposite it
One blade with a "W" inside, 18" diameter, 3 1/4" bolt hole centers, 2 5/8" center hole. This particular one was painted white by someone that is what you are seeing.
Is this not a 3871296. It is also sold pending payment but I have more.
