Technical AV8 Radiator to fan distance

Morning All.
I am looking at putting a full hood on my 30 AV8 and it taking some measurements I have found that the top of the radiator is laid back a little over an inch to far to allow the hood to be fitted. In the current configuration the fan is about 1 inch from the rad.
If it move the top of the rad forward I will have a bit over two inches between the fan and rad.
My question is, how much will this harm cooling (especially if there is a full hood fitted)?
Thanks for the info.

1" is the gold standard I believe. At lease that's where I put mine after a lot of research on it.

 

A shroud would help , but two inches should be fine.

 

Can you post pics please?

 

Add a descent shroud and it'll cool better than ever even if the fan is two yards behind the radiator.

 

Here are some pics

The hood measures 30" down the center

Current position of fan is 1" off rad

Top is laid back a fair amount

Any one have a pic of a shroud mounted... I am interested in how it is secured around the top.

Thanks again

Try it before investing in a shroud. Aluminum radiator? Should cool well. Any cooling issues now?

Yes. Aluminum radiator. No cooling issues now aside from hot days in heavy traffic...gets into the 200* area.
Just cant figure why it was assembled this way. The tabs at the bottom of the rad sit flush on the crossmember now. If I move the top forward would I need to wedge the trailing edge of the mount tab? It will be raised up off the crossmember a bit.
Thanks again

I'm building a 30 with an 8BA and a 32 grill shell with the stock hood and have about 1 1/2" fan clearance, I had a 28 with a flathead and had a couple of inches clearance and it never cooled quite right.
