I have a 9" 3500 stall art carr convertor in my car now, i was wondering if i should upgrade it. I am upgrading everything else, the engine is a 252, with fully ported gn1R heads, 220/220 513/513 hydraulic roller anderson cam, 70 mm throttle body, extreme fmic , 67/65 billet journal turbo. I am keeping the 2004r in the car and wanted to know if my comvertor is good for my application. Or should i change it?
