I'm am looking to replace the radiator in my 67 Camaro (manual transmission).
Currently it has an aluminum aftermarket radiator that I bought largely because it was fairly inexpensive at the time (20 years ago). It works fine but has some issues I'm not fond of.
First off it has no petcock to drain the system ... have to pull the lower radiator hose to drain. Then it does not appear at all like a factory radiator. I also don't like how it is mounted on the core support either, a bit of a hack job. I don't think the connector nipples are the correct size.
I think I'd like to simply go back to a factory style radiator and resolve all of this clutter.
I see there are 20.75" wide radiators and 26.25" wide radiators (looking at Classic Industries catalog). I assume these widths are the core size, not overall radiator width. The opening in my core support is 22" wide. My current fan shroud is 21" wide at the front (radiator contact/seal point). Width of current radiator core is 22"
Living in the Mojave Desert where summer temps regularly range between 105 and 115 in the daytime I want to have the cooling system capable of handling about anything in that regard. The engine is a rather mild to moderate build. Aluminum heads, hydraulic roller cam, full length headers, 2.5" Flowmaster factory style exhaust kit (meaning transverse muffler) etc. ... but not *Hot Rod* by any serious means.
I figure I'll go with a 4 row radiator no matter what just to maximize the benefit on that count.
Here are my questions ... Do I gain much by going to the 26" wide version considering my core support opening is only 22"?
I see some 1/2" holes in the core support that I presume are the factory radiator mount points?
I understand the aluminum radiator scenario with the larger tubes and all that, but if a factory copper/brass radiator will serve my purpose, I'm ok with that. I actually have a big Griffin aluminum (factory fit) on my Mach1 with the 1.25" two row core.
What is there here that I ought to know before I go out spending money on parts?
Any input appreciated. You guys always seem to toss something out at me that I had not thought about and usually it is helpful ... so toss me what you have to offer.
