Before u go and spend a ton of $ on a rad. try 2 find a race shop in your area that specializes in roundy round racers and try to price 1 through them,I paid right at 200 bucks 4 mine and they ordered it to the size I wanted with the inlet&outlet where I needed them,and I love it,it cools a 650 hp chevy w/no prob.
tHERE IS A RADIATOR OUT OF A EARLY TO MID EIGHTIES CORVET MADE OUT OF AL THAT IS AVAILABLE AT ALMOST ANY STORE FOR ABOUT 125. sUPPOSEDLY IT WILL FIT IN A Z CAR WITHOUR PROBLEMS. THE WEIGHT SAVINGS IS ABOUT 5 LBS. WHICH IS WORTH IT TO SOME PEOPLE.
Is who makes those units that arizona sells. I think you could get a better deal by contacting Ron Davis yourself. The radiator is a good unit, built for heavy duty use, and I believe it bolts in(the old ones used to) but it is also at least $100 more than other good AL units. Look for Howe, AFCO or Griffin they all make good radiators that like Flame said will cool high hp V8's for around $200. I'm glad I got my AFCO unit and mounting it was very easy and inexpensive.
First, contact AZ Z Car to make sure he is actually still selling them. A lot of stuff on his web site is no longer available.
I have debated constantly about the need and desirability of an alum rad. Even if money is no issue to you, it could prove to be a waste of money as well as reliability problems down the road.
Let me explain:
There are a lot of folks (like ZZZZZ in Arizona) who don't think anybody but non-street racers need a big radiator. Most everybody agrees that the stock rad sucks and even some of the aftermarket OEM replacements aren't much better, either.
Like the guy posting above says, you can choose from a number of Chevy radiators that will fit your Z with very little modifications. If an alum rad breaks, you gotta a bigger hassle trying to fix it. This is especially true with a custom.
My advice, get a JEGS or Summit Racing catalog and drool over all the opitons there. Then get back on this forum and get the lowdown on exactly which Camaro rad spec you need. Then choose from the catalog.
