I went with an Art Carr 200-4R three years ago. I have a 408 stroker, Dana 60 with 4.10 and 27.75" tires. It has a 2800 stall and I have loved it. I used the TCI adapter because that's what Art sells. It is one huge piece of aluminum. You will need to cut it down. I am having trouble this year, though. I'm spitting fluid out the vent. A lot of fluid and only when hot. I called Art and he said my cooler was crap and I needed a stacked plate cooler and that i can buy the same size cooler and get 5 times the cooling with a stacked plate. I asked him why it would all of a sudden not be cooling enough and he told me to just trust him. It didn't help. Then he said change the filter. No luck. I called a local guy I know and he says the converter is likely slipping or failing which causes a lot of heat. So I read up on it and sure enough, there's a lot of evidence to support this. I call Art and he says the converter will not increase heat. I tell him that from what I have learned it certainly will. He got all pissy with me. He told me to lower the fluid level a pint. I told him the transmission pissed out more than that on the way home last night. He is not very helpful and when I told him I had installed a B&M Supercooler he took me to task for not buying his. He said the B&M is too small. By that time I had had it with him and said, correct me if I'm wrong, but you said if I buy a stacked plate cooler I can buy the same size and get 5 times the cooling? This is bigger than my old one. He hemmed and hawed. I'm done with Art Carr. From now on I stay local for everything. I'm bringing it to the local guy next Monday. He says he can drive it and tell me if the converter is locking up or not. He also makes an adapter for the TV cable to throttle linkage that allows a tighter cable, more than all the way open at wide open throttle. He says it increases line pressure so the transmission shift points are better and the shifts feel better. He's going to install that for free for me.
