between the frame rails it is 29" with the lip removed at the top of the rail, the core is approx 1/2 wider ( 1/4" per side) than the opening, that a is un cut core support opening and it was a origional slant 6 car if that makes a difference in the core support, the one I ordered was 555-52018, the info says Ford but it is Ford/Chrysler and also it has NO trans cooler built in but does have a bung for a drain petcock, I am building upper and lower mounts like I have done for the other one that was in the car I think side mounts could be made also.

The actual core 18.5 x 28 The 31, is to the outside of the cross flow tanks.

And IMO, doesn't matter how close your fan is to the rad, It could benefit from a shroud.

I have a brand new A body/small block ECP radiator with dual fans and controller I'd be willing to sell. No coolant went through it. Didn't work for my particular application (don't ask, nothing to do with the radiator) so I ended up going back to my old rad and modified that instead of cutting up a new one.

I was gonna send it back but never did, just sitting in my garage.

ECP rad.

Fan controller

Thanks for the offer but the hose fittings are in the wrong place. I really would prefer a cross flow after all the info i recieved.

Anyone have a linc to the guy that sells champion radiators on here. Cant find his ad.

I didn't think the champions were cross flow.

If you google champion radiators he comes up. IIRC he's in California.

I just googled it and couldn't find him.

Any thoughts on this one? Will it cool big power without weighing 500lbs?

There is a Griffin cross flow for sale in the race parts classifieds...

I seen that. I think the fittings are wrong. Outlet needs to be dr side and inlet on pass.

Wish i knew someone who had tried that one.

Sorry if I missed it but what is the application here? Guessing big block A body?

511 filled with victor heads in a 67 barracuda.

I'm alittle afraid of that one all thou I'm not totally afraid of the double pass with 55 gal water pump. I'm currently waiting for a price from champion on a double pass just to see. its just so tempting to get a $150 crossflow, which might be enough.

Here is the one I use - fits perfect works good!

I'm not a big fan of the cross flow and like I said, not a big fan of the multiple pass radiators. Stewart may not have been totally correct with the 16 times more pressure number but I'd bet it's not that far off.

You don't need pressure to cool the engine you need flow. Making the coolant travel further decreases flow. That is always bad.

Just hate to see you spend your money twice.

I'd call some coolant people and see what they say.

Been running the 2-row cross-flow Griffen for at least 14+ years and a Moroso drop in water pump and it cooled good enuff to romp in Vegas during 114+ heat and in the Hesperia Ca desert I live in. My new Moroso w/p makes it harder to come up to temp but that's a good problem to have.............REAL WORLD TESTING..........Not mag read.........

I had a 22" factory radiator in my 70 426 hemi cuda that would creep up in warm weather and traffic and replaced it with a 22" 3 row champion and it stays cool now. Fit was good only had to drill 1 lower hole. Mike

I will take a look at this tomorrow when I have some time. thanks for your info guys. I'm going to give wizard a call tomorrow to see what they have to offer as well. thanks again

I was just looking and measuring the area I have for a radiator. I have a lot of moving stuff around to fit a large cross flow in there. trans cooler and lines will have to be moved. It would be easiest if I could make a down flow work.
