It's from a good friend with this extra rad.I know it's good and no leaks because I put my inlet & outlet caps on it filled it with distilled water and pumped up the pressure on my radiator pressure I'm not a dumb *** rookie, I have built several race cars and many engines for customers for approximately 30 yrs.now.I am just asking a simple question to see if anyone has/ is running a 22" radiator with a big block. You don't have to be a smart *** dude..You know what,I am just gonna dump this abodiesonly site and use my own knowledge .It probably better than what y'all know anyhow.. Good buy..
