,,,,,,,,,I would say the fan blade depends on the size of the shroud and the radiator hoses,,,,,,,,,you put the biggest one on that does not hit or rub. And I think the most common one is the 18" fan blade. And in case you are interested, a 6 cylinder shroud has a 19" opening,,,,,,,,,,

went out & measured mine- fan blade dia.= 15 inch -has a large type clutch also - I also have a fan blade with clutch thats a 16"=-a little-has same clutch on it - i do believe the 15 inch is the origional one .The pressure cap is a 14 lb. one - u can use also a 18 lb one yet the higher u go the higher the boiling point is raised. if ur @ sea level or near it id use the 14 lb one -Hope this helps,matt

So Twinpilot, do you have the stock 2nd Gen crossflow radiator and the V8 or 6 Cylinder type of shroud? These shrouds have a 19" opening for a 18" fan. I am thinking a person could improve on their airflow by filling that shroud opening with as much fan that will fit in there without rubbing. I think Livewire might be wanting to use a 6 cylinder shroud on his V8,,,,,,,,

Yes , I do have the V-8 shroud. The 16 " fan I have is actually a little larger 1/4"?? maybe and as i am measuring it across for diameter. it could be larger yet as the blades are not across from each other. I bought this gen2 1967 van about 1 & 1/2 years back and was totally disassembled - was a roller yet in primar & all doors, seals & glass were removed. So=== Im dealing with a disassembly that i didnt do- so im slow at all the mods & rebuild. I did get the 383 motor installed , just before the ice & snows hit us here . Will test fire in april /' may next. Currently -looking for some electric , fold down seats for the front cab area. Also if Livewire has a 6 cyl shroud?? there is a guy on ebay that is selling a alunimum shroud that is made for the v-8 vans. I almost bought that one -yet didnt need it & its still available,matt

Also- from experiences with fans & shrouds - the larger the diameter that will fit in the shroud- with about 1/2 - 3/4 " clearance is best and the fan blades need to be almost to the end of the shroud- Gives the usage like a Venturi effect.

Livewire I have a brand new fan blade that was the wrong size for my first gen if you need one.

I think Livewire is inventing a system to put in his 1st Gen,,,,,,using the 2nd Gen crossflow radiator, surge tank and some sort of shroud, and a V8 engine, so we pretty much got him covered with all the different parts available to him,,,,,,,,,,,,,and if that is the picture of your fan blade, Rich, thats for a waterpump, not for a clutch.

Denny Smith in IL has a 66 No-Door that he is putting a 454 in. He's using the cross-flow radiator & also the 6 cylinder shroud. Says it is a great fit with the 454.
That is where I got my idea to use the 6 cylinder shroud.
I will keep everyone posted. Brad
