ECU P4120534 Super Stock / Pro Stock / Nascar

image.jpeg image.jpeg image.jpeg All right. Here are the pictures of the gold box I have. I thought there was a part number on it. There isn't. But I did research the best sink on it, and I believe this is the 1980's gold race box.

I also know this was used on a street/strip car. I also know I've personally tested it, and it's only losing 1 degree across 10,000 RPM. I also ran it to 12k and it didn't lose any more.

IMO, even this box is usable for a street/strip car. Regardless of what Chrylser said at the time.
