5.3 cooling question

im swapping a 5.3 into my yj. im thinking of using an aluminum stock style radiator from ebay * i know i know..but im really cheap* instead of a 500+$ conversion specific one from like novak or advanced adapters...anyone with a 5.3 who has NOT used a pricey conversion radiator please chime in with input...

the 2 im thinking are like these



now the first is factory styles...2nd is "conversion" style. im liking the first one for ease of setup.... but with either i plan on getting an adapter for plumbing in the steam port from the heads...any thoughts?

I have "heard" that an older Saab or Volvo (can't recall which, Google it) will nearly bolt in, and will cool an 8... I'm considering it after I build my SBC up. That would likely be a cheaper alternative.

For my swap we used a universal radiator from a race shop and welded tabs on it. It was around $200. It is cooling the 5.3 just fine.
