im thinking of getting a 22" radiator for my camaro so i can move it back a little closer to the engine. My idea is to get it closer to the fan so i wont have to run a SHROUD, and if its further away from the bumper the radiator shouldnt receive too much damage from a wreck. ive seen a camaro with this setup before but was wanting some more input on it, also is the 22" radiator gonna be big enough?

My experience has been that the most important part of the cooling system is a well designed shroud.

If you're married to this idea of eliminating the fan shroud, build a shroud between the grill opening and the front of the radiator. This will direct all the air flowing into the front of the car thru the radiator instead of around it. That will help under green, but it won't do a darn thing for it at idle.

Don't even think about running without a shroud. To get any kind of efficency out of your rad it has to be properly shrouded. As for the 22" being enough rad, it all depends on how much power (heat) you make. If your stock you might get by, but if its modified very much I think you could be in for alot of overheating headaches.

sstocker31 my engine is mostly stock, no port work, 462 heads bowtie intake it has good rods in it and flattop forged pistons im running a crane 490 lift cam.... you still think the smaller radiator WITH a good shroud will be ok? oh yeah and i dont run a nose piece so the engine gets plenty of air to it

I would run a should and keep the radiator as far from the fan as possible. If you get hit and the fan goes through of hits the radiator you are done not true if you get hit and maybe just get a hole in your radiator. You could fix that with jb weld and run the main but a shroud is a must or your came will be a bust.

Yes I think you will be ok for cooling if you set it up with a proper shroud. Make sure the fan is about 3/4 the width of the blade inside the shroud and only leave about 1/2" space between the outside edge of the fan and the shroud.

Been running 2years now without a shroud. 22" rad, 1" from the fan, nose closed. I do have an air dam under the nose tho. On a heavy track it will get up to 230, but on a normal to dry track stays about 200-210.
