View Full Version : Is the 772 Fan for 350's & big block? Jim J Mar 5th, 02, 06:33 AM I'm putting together a 69 and have a 350/300 hp. I want to get it right. The books I have indicate the 772 fan is for 302-396-427. Is it also correct for 350/300hp? Its a Pace Car, but I wouldn't think that matters. Thank you in advance for the help.

My car is a non A/C car. To be correct I should look for a 5 blade right? KevinW Mar 5th, 02, 02:55 PM Hmmm? I think it would be the 4 blade. I think the 5 blade was the clutch fan for 67 or maybe 68s, but I'm not sure. Kevin Jonesy Mar 5th, 02, 03:35 PM Jim J Kevin is correct. The correct fan is the 4 blade type for your car. The original GM part number is 3927791 and was used in conjunction with fan blade spacer #3927792 JohnZ Mar 5th, 02, 03:41 PM Without A/C or K02, the L48 got the same fan as the base V8 - the 4-blade 3927791 with the aluminum spacer. With A/C or K02, it got the 7-blade 3947772 (or 3956684) fan and the clutch (3946049) - same as used on the Z/28. ------------------ JohnZ CRG '69 Z28 Fathom Green [This message has been edited by JohnZ (edited 03-05-2002).] merch120 Mar 5th, 02, 04:39 PM I have one of those fans and spacers with those numbers if you are interested. Well, I think I do. I will need to double check the numbers, but they sound very familiar. The fan and spacer has been blasted and is already painted. X77D80 Mar 5th, 02, 05:48 PM My 350 pace car has its original Harrison radiator (2 row) with four blade fan (and spacer). It actually pulls air very well. Though you do get a little more fan noise as compared to a clutch fan. ------------------ - John - 69 Z/28 (http://www.camarogenerations.com/memberfiles/firestone.html) 69 Z11 (http://www.camarogenerations.com/memberfiles/firestonez11.html) Camaro Generations (http://camarogenerations.com/) Member WCA Member Jim J Mar 7th, 02, 07:26 AM This is info I couldn't find in a book (I have a few) Thanks for the help |
