Hi everybody. My name is Eric. I have a 1973 Cuda I found in a field when I was in high school and I've been building and rebuilding it ever since. The car was raced before I found it and the original motor was gone so I've never been concerned with keeping it original. It has gone through many changes and currently has a new stroked and supercharged 440 in it. It started off as a mild stroker build but of course it spiraled out of control into what it is now. It has a forged crankshaft with H-Beam roads, forged 8.5:1 pistons, Edelbrock Rpm Heads with enlarged valves, Lunati solid roller cam with Lunati 1.5 roller rockers, 2" Headers, Edelbrock RPM intake with a Dan Davinci custom 950 Blow Thru carb, Vortech centrifugal supercharger running around 5 psi at 3000 rpm, MSD ignition boxes and electric fuel pump. That engine wasn't supposed to get that crazy but it somehow did anyways.
So one of the big problems I'm having with it is overheating. The engine can go from cold to 180 in about 3 minutes idling from a cold start. It runs fine until I get into traffic and the temp rises pretty damn fast. I'm kind of convinced the radiator is too small but several people have told me they don't think so. The radiator is a Wizard Cooling radiator that was custom built for the car. It has the same height and width as the stock radiator but it has 2 cores which is their thickest radiator. It has a built in shroud with 2 Spaul paddle pans. I have also moved the oil filters to the side of the engine compartment where they run through an oil cooler before going back to the engine. With all this being done, it still gets hot fast. I know the thermostat is in correctly and is a 180 degree thermostat. I'm pretty certain I have no air pockets in the system but I may retry to bleed it just incase.
So this was by far the biggest most powerful engine I've ever built so there is a lot I am still learning. Just wondering if you guys have any helpful tips you've ran into with big hp street engines in "small" cars. Thanks very much!
