I bought a 280Z clutch and fan from someone on ebay. I restored the clutch and the fan and tried to mount it on my '71 240Z. I have a new 4-row rad in the car and a 280 (F54) engine. The fan assy is too thick to mount in the car. It is about 5/8" thicker then the 240 fan assy. Maybe I got a 280ZX assy. What do I do? Is there a thinner or shorter clutch for the 280.

Maybe the 4 row rad is the differance..?

as you probably know the 70-and I thought some 71's came with the metal fan and the clutch was diffrent , I also have read from looking up on building a stroker motor that the f54 had some clearance issues , I know on my 72 I have a 4 core and it fits fine with the 72 and up plastic fan / older clutch

here is the link reguarding it , if you scroll down it talks about fan distance and you might be correct in the thought that you might have a zx one , good luck

Take a look at the metal mounting surface of the fan. If it's at the front edge of the fan it's a 280 unit. If it's recessed down towards the bottom edge it's a 280ZX-810-Maxima fan. Being recessed will make it sit farther forward to clear the longer crank pulleys that the ZX etc. had.

Aha! It set down in the plastic. It is a ZX fan. It is 2 7/8" thick and the stock metal/clutch assy. is 2". I need the correct fan assy. Thank you people!

Get a 280 fan and you'll be fine as long as you're not running a 3 row crank pulley.
