Scody, sounds like a great set up, wish I had the room to run something like that, but I’m running this thin fan cause lol…I can’t fit anything else in there.
MV, running a shroud.
set up I have now with griffin rad and this fan is ok if the day it’s hot, but when it is hot I’m shutting it down due to heat after a short while.
let me ask, would I be better off running a 6blade 19”, or a 7 blade 18 or 17”?
is there a company or shop that builds custom fans?
Here's the one I am gonna put on Vixen next.

That motor will work with a fan clutch.
Water pump flange is same as stock 383 car.
Your clearance problem is from the radiator sitting too far back, aluminum pulley thickness (not much).
If you are running stock Trans mount, the motor probably isn’t shifted too far forward.
that hemi aint any longer than a 440 , there is enough room if u get it right . ditch the flex fan .
ur engine bay should be the same as my 68 barracuda ------View attachment 1715791314
mine is 3 1/2'' also , griffin 2 row, w/ 1 1/4'' tubes . cut the mounting brackets off and heli arced 1 1/2'' x 1 1/2'' angles flush with the front , to get that .Looks like a great set up. I have 3.5" between the cross support to the flat on the water pump pulley, how many inches thick is your rad/fan set up? Not sure why everyone keeps saying to ditch the flex fan, have stated and pics confirm I'm running a hard blade fan, and it's direct mount - I don't have room for a clutch.....but I agree if I were running a flex or a clutch, they would have been the first to go. I hear what you're saying about motors being the same size, but the tape measure doesn't lie, and what I have to work with total is 3.5" for a complete rad/fan set up.
If this round of small tweeks (puller fan, octane, timing) don't do the job, then in the spring its off to Wizard Cooling for a full custom set up that will fit with what I have to work with. I'm certainly open to ideas around how to create more room - I've considered a custom cross support that will allow me to locate the rad forward, I've looked at kits that will relocate the water pump to create room at the back end, cutting the opening in the cross support larger for more air flow - all options are on the table.

How much did that adjustment gain you in depth? Thanks.
dont remember but the rad. has to be right up against the cradle , no gaps.
A short fan clutch is mandatory , hayden 2947 i think --------
Have you checked the lower hose? It is possible to collapse the lower hose with rpm?Looks like a great set up.

Just covering all the bases
Way cool car!
Short fan clutch is mandatory. Short. So it'll fit. A long one won't.Why do you say a clutch is mandatory?
Make sure the hose is hot before you check it.Thanks! - Never thought of the lower hose, will check it out, but truthfully I think my issue is much bigger - or rather I simply nee more cooling capacity.
Make sure the hose is hot before you check it.
Run it up tp 2500 rpm when you check the hose.
Do a direct drive fan, you will lose 20% fan speed with a clutch set up.

That is does not collapse. I put a spring in mine just in case.What am I checking for on the hose, that it continues to flow, or that its not collapsing with rpm?
Kent hit the nail on the head.What am I checking for on the hose, that it continues to flow, or that its not collapsing with rpm?
For max air flow you can not bet a direct drive fan.I'm doing direct drive out of necessity, as it's all I can fit, no room for a clutch. I still don't understand why people are saying you need a clutch???? I think the DD set up has better pull and take sup less room.
You didn't read my response, evidently. Bob didn't say you NEEDED a clutch, PERIOD. He said he needed a SHORT clutch for HIS to fit.
