I’ll second that. One of my first mopar lessons. I bought 70 Cuda 383 with a fresh built motor. The fuel pump diaphragm ruptured after one week of driving. It ran just enough to keep fuel in the carb but the rest went in the crankcase. I called the shop that sold me the rebuilt car and the first thing he did was pull the dipstick. His eyes got real big went the “ oil “ was all the way up the stick. He thought I ran it out of oil. Lol. He changed the oil and pump and gave it back to me. The warranty lasted about a week. I was stuck with the rebuild. It cost $800 for the complete rebuild AND a used 4 speed swap from the factory 3 speed. Took me all Summer of mowing yards to pay for that. Man, those were the days. Hamburgers for a quarter, too. Lol.
