What you have may work fine if you can keep the temp consistent....For the drags, not a lot of radiator & fan is required....Its the street that really tests a system....So for drag only, any universal 2 row 1" -1.25" tubes, typically a 31x19 will fit with a little work, and a set of cheap 12" dual electric fans....I ran that style setup for the last 20 years, until I put a Calais Hemi cast iron block in, and that damn thing is tough to cool on a 90* day....Switched to a 1.25" tube & spall 14" fans and a 50gph water pump...did the trick....
For me, I would find a wide tube universal rad that will fit, with a sheet metal shroud and 1-fan, and go with that...I like the Griffin ones best with the 1.25" tubes. Had Becool, and the Griffin way out does it. I had a shroud made for mine by Wizard cooling to gain the over sized fans, but for racing, one is all you need.
