The radiator?? Probably....7.2L is a bit more than 5.7.....but I'm sure there's more variables than just displacement. That being said, what's the published flow of those fans?? And is that a loaded cfm? I know there's a technical term for that, but in layman terms a lot of these cheap fans rate their fans with they're not pulling any load. Reputable companies publish it with no load and some sort of static pressure? applied to it. Someone with a giant brain can explain it better than I can. I'd be leary of their fan setup though. I'll be changing my radiator soon to something with larger tubes....even if it's 2 row.
