looking for opinions for AN radiator hose conversion

[tmaleck]

The new shop is making progress on my 68 Charger. The engine and radiator are not stock. Black flex hose or the stainless flex versions A: look like crap B: look like crap. I've spent a ton on the engine bay and the motor and don't want to open the hood and see all that goodness connected with flex hose.
So I'm looking at going AN hose. I can readily find -20 (1 1/4" ID) hose and fittings. I seen some -24 stuff (1 1/2 ID) but it is scarce and double the price.
My question is -20 AN going to flow enough to keep my 440 cool. I have a 3 row Champion aluminum radiator with twin Spal fans on a custom shroud. I'm not racing or any real hard driving. I'm a bit concerned because the factory radiator used 1 1/2 and 1 3/4 hoses. Any thoughts?

Have you looked at Gates Power Grip clamps? I had to extend my top hose as my engine is set back 2 3/4" from stock.

3 feet should do both hoses. It is only 20 bucks more for the 24 vs the 20. Are you going to have male an bungs welded on each end?

I saw that. The fittings are the real cost. Earls is $160 average per fitting, vs Auto Plumb around $50. I can't find any other -24 fittings.

I went with -20 on mine for the upper and lower hoses just to be on the safe side. Car runs cooler than any of my other more stock-ish builds in my other cars with more than twice the power street driven.

Nice look. Did you use the Autoplumb stuff?

Mine are mostly Fragola hose and Fittings.
