I ran a Omni/Horizon radiator in my SB for
a number of years.. was OK but heated up on
the return road.. on yours the biggest factor
is the small fittings going to and from the
block.. you can change the to copper so they
are smoother on the ID

Like Dartsport540, I ran the ShoGun system on my old car with -10 lines and I could let that car run in the heat of Vegas for a long time. For a bracket car I expect it to sit and run for however long and not have any cooling probs. You go rounds and they start running you back to back.... you gotta be ready. I did run the ShoGun "bilge" pump and my Mirada had a radiator similar to an A body replacement piece. Dodge Dynasty electric fan with shroud.

I used to have one of those Durango pumps at work, but never got a chance to put it in a bucket and see how much fluid it would move. It was noisy, but still worked. I was kind of curious as I've heard of people using them on race cars.

Pics of cooling system. I have ran this system since 2004. Friday night at the track , I had to change the remote water pump. It started getting noisy. I did have another Shogun Z pump in my trailer . Works Good again...

Nice thank you very much.

Check out the stewart EMP inline water pump. One serious bad mofo of a pump. I had a CSR on a hot running motor once. Didn't want to get a bigger radiator, or do much else for that matter. I put one of those emp inlines on and dropped 25 degrees, just from increased water flow.

So instead of screwing around with that scirocco radiatior i went ahead and ordered a lightweight 26"x19" two row dual pass griffin with AN inlet and outlet. For pump i got a allstar 20-25gpm pump and i am going to use -12an lines.

I am going to pull that shogun manifold and drill out the restrictor in it. Should have good enough restriction with the dual pass radiator.. I will just have to come up with a good fan setup for it. Will probably hit up junk yard and find something.

Note, the Dual pass is not a plus for cooling in your application, and if possible, you may want to reconsider, ie, for one, it doubles the radiator water flow restriction vs a single pass, almost like taking two steps forward, and one backwards, IMO

I would like to hear some discussion on that subject. If anyone has input or discussion on dual pass radiators.. Worst case I can return the radiator i have coming. It was a shelf radiator not special made for me. Another reason I chose the dual pass was the inlet outlet would be on the driver side. Which would make things nicer looking and less crowded.
