When I originally bought my 47 I had planned to seriously hotrod it. I was building a 400 (Mopar, thank you!) stroker motor with 500 ci, aluminum heads and fuel injection - 540 HP and over 600 lb/ft of torque!
But at the same time I was driving the 47 with the stock motor, and I noticed something interesting. The car didn't accelerate well, didn't stop well, didn't go around corners well, but when driving it I was living with it's limitations and just mellowing out. Waving to people that waved at me, etc.
Then I considered how much I would have to reinforce the car to stand up to that engine without tearing apart, and changed my mind. I decided to build the car as a 50's hotrod with a tricked out flathead six.
It took me the better part of 5 years to figure out what I wanted, find all of the pieces and get it assembled, but I enjoy going for a ride in it every time I can. The Killer V-8 would have been something you would have had to be very careful driving, and wouldn't have been near as much fun. My flathead has a neat sound that gearheads appreciate, nobody tries to challenge me to race, it's just a cool car to roam in. I'm still very happy with my decision, although I am looking forward to putting front disk brakes on it!
