    Correct the size is more important than the # of rows.

    I’m pretty sure my Dewitt is a 2 pass and so is the C&R im looking at

    Correct size of what?
    You want the biggest rows you can stuff in there. I wouldn't mind a two pass, but in reality a single pass radiator with 2 1.25 inch rows will out cool my current car quest made in China 4 row(with I believe 3/8 inch rows) radiator. While it's adequate, I want the extra capacity as I feel if mine ever starts to clog(even though I change the coolant yearly) it won't be enough.
    Looking at the size
    Brass: 3/8 x 4 would be 1.5 inches
    Aluminum: 1.25 x 2 would be 2.5. Inches per each tube.
    That's a LOT more surface area for sure. Just a ROUGH guess in the surface area let alone the better fin/tune spacing would be:
    Assume the core itself is 23 inches wide....
    23 x1 is 23 sq inches per row.
    Now assume there are 40 rows(on the lowside) 23 Sq inches x 40 would be 920 Sq inches more surface area.
    Aluminum total: (2.5x 23) x 40=2300
    Brass total: (1.5 x 23) x 40=1380
    That's 60 percent more surface area assuming a 2 dimensional figure (again rough math) this
    Edit:yes I know surface area is not everything, but we can know that it makes a large difference here.

    I'm been running one of these for the past 8+ years

    http://www.entropyrad.com/1970-1981...or-with-dual-hp-fans-and-aluminum-shroud.html

    I paid around $500 for it back then and can affirm its an absolute beast. I've had the car sitting in the drive thru for 20 minutes with the a/c on in 100 degree Texas heat and it runs a cool 190-195 degrees.

    I think the fans make all the difference, after having elec fans on both cars I'd never go back to a mechanical fan and shroud setup

    Interesting that doesn't look as wide as what's in my car right now!
    Do you know the dimensions? I'm curious as to how thick it is and how wide/tall it is. Now I need to go measure mine
