I remember hearing a story that said the Pinto was more aerodynamic going backwards.... Well, they did make a cool looking F/C. I remember when they came out, along w/ the Vega, I think 1971. War story: when I bought my Pinto, I really liked the engine, 2000 CC 4 banger. I thought the Vega was the better looking car (altho they had lotsa problems w/ poor engine design. The block would crack) So my wild hair was to get a Vega & put the Pinto engine & trans in it. Heresy! Once at the old Irwindale, I raced my Pinto against a Vega. He got me off the line, & 17.0 seconds later, I passed him in the lights. We talked & he'd done the same w/ his engine as mine, ie: aluminum intake manifold, re-tuned the carb, etc. I had a Mallory distributor & Offy intake manifold. Engine was stock. I read Popular Hot Rodding articles on Project Pinto & that is what I followed w/ my car. Even had it dyno tuned by Ak Miller, 105 HP at the rear wheels. I think it was 1/2 second quicker than pure stock.
The guy who was runner-up in Stock at Lions Last Race was in a Pinto. He was running mid 16's w/ stock exhaust manifold (class was "pure stock", could only blueprint the engine). I think his name was Matt Esposito??? He did really well in that class in 1972. Also, Dave Benesic (Sp?) who won the race in a Buick I think, also did really well at local races. That class was strange, no headers, etc like today in Stock. You were allowed to run a cut out & that was it.
