Hi everyone, i wanted to provide some information to other members suffering with over heating issues. I struggled for years with my 383 ci 560 hp engine running hot 210-220* in Phoenix when the ourtside temps got over 100* here. I tried everything from springs in my hoses, adjusting timing, fans front and back. I replaced the stock radiator with a 3 row unit with a condenser in front and i still had issues cruising around town. It had two HD Spal 11" fans i even added a 14" pusher to the front and still had issues around town. In my drive way it ran 195-200 after 20 minutes and on highway it would run 200-205 at 65mph. As a last ditch effort before i was going to sell the car i tried a 2 row dual pass radiator from Sweet Componets. I know the units are way too expensive with their assembly frame and most people arn't willing or able to afford to spend really big bucks. So the issues was my 3 row with a condenser in front was NOT passing enough air through the radiator to cool the water down. It was just barely able to cool at 65 mph. So if you are having a similar issue try a dual pass radiator with dual puller fans. My temps in January had the engine running 170-180 barely. Now that the temps are hitting 100+ degrees i average 185-195*. Hopefully this my help others struggling with over heating engines! UUiXIGF1QvyO0dRhCjLbPA.jpg
I think that is the best looking radiator setup on the market. I was on a business trip to Phoenix and got to go to the guys house that owned Sweet Components, can't remember his name but a really nice guy. They were very reasonable at the time about 6-8 years ago. Long story short I have a Newman Car Creations chassis that was just painted and for his set up to work I would of had to notch weld and repaint that section. Wish I would of but I decided against it didn't want to have to redo things. From what I understand he sold the company and thats when the price doubled.
That Sweet radiator kit is VERY nice. Talk about doing it once and doing it right!
The only downside is the BIG price tag but in the big picture, with how much money is in that car, it literally made the difference between enjoying the car or selling it! It was probably still less than 5% of the total investment in that car. I'd say that's a good investment.
For those of you that are reading and thinking 'if only it was a little more reasonable', stay tuned, Cold Case is going to have a very impressive answer for all of you Tri-Five owners very soon.

I don’t think a non polished dual pass radiator would cost a lot. It’s the core support engineering that is expensive. Now that retirement came early, the owners of a the company I worked at for 15 years sold the company and mainly senior employees were let go on 5 minutes notice. So I know I could build one. It’s just 1” square tubing and some welding and you could build this setup for less than $1500. Like Ccas said this was a last effort to be able to use the car from June to Oct. So back to the reason of this post, if you are having over heating issues there are a lot of things to look at, if the car manufacturers can build a car or truck that never over heats in Arizona summers if working properly our classic cars shouldn’t over heat either. Feel free to contact me if you are having issues as I have learned a lot about the issue. Maybe I will work on a check list of things to check to solve over heating issues now that my days are free!
Don't see where to get this setup directly from them.
Hot Rods by Dean bought the manufacturing rights from Dave Sweet. They are here locally in Phoenix. But donít expect any help with the install unless you buy it from them and they do the install. You will need to find hoses as the lower is a 1 1/2Ē and the upper is a 1 3/8Ē. It is a nice looking set up but it was big bucks. If you live in a hot climate or have a high HP engine a dual row , dual pass is the way to go. I took car out to a cruise night in Phoenix itís was 104* and it ran 185 to 190 I am happy about that.
