The Nerd lucked into a deal on this 58 reprobate Plymouth. She paid 350 dollars for what was left of it. Six months ago, she got on the computer and rounded up most of the missing or damaged parts. The car original had the old Powerflo 6 engine. It had an unimpressive 132 horses and 131 of those horses were dead or very sick. She has been working on it behind closed garage doors. Being herself, she won't tell anybody what she as done to it, When the Nerd fires it up, It sure doesn't sound like a six cylinder engine. My guess would be a heavily reworked 340 six pack backed up with a modified torqueflite transmission. Mind you, that is only a guess.
