273 Build

That is the original. There is "ac" stamped on top so Mopar must have used the air conditioning radiator for the hipo motors. I don't think I have a heavy duty cooling option. These radiators may be hard to find but I haven't checked. I never had any overheating problems before and I hope I won't have problems with the new motor. Mike

Great work, Mike. Glad you're taking the obstacles with good humor. May as well. Besides, taking the time to make sure it's right means more trouble free play time later.

MAX cooling was part of the A/C package and trailer towing package. If you have the build sheet, check for 492 for the Max Cooling Pkg. My HiPo had air so I don't know if non-A/C cars had the package. There is nothing in the literature to indicate that that they did. FWIW the Formula S package which included the 273 HP did not include Max Cooling.
