Two machine guns strapped to the engine with plastic ties?...... defies reason and credibility......car engines are HEAT PUMPS....plastic ties melt at tempratures much less than the operating temp of a car engine....... I stopped reading right there.....
Maybe it was the intake manifold. They look a lot alike unless seen when the engine is producing high power and the exhausts tend to glow red.
Some heat ties are very heat resistant.
