NASCAR had nothing, not one thing, to do with the development of the CobraJet Engine. And that is a fact.
The cobra jet engine was the brainchild of the good folks at Tasca Ford.
A Dealership in Providence Rhode Island.
A Tasca Ford Employee Blew up his 390 that rested in the engine bay of his '67 Fastback Mustang.
While repairing the damage, the fellas discovered what happens when you put 427 medium riser heads on a 428 police interceptor motor.
That and a 735 cfm Holley carb.
The story goes, that while demonstrating the new engine to some folks one night, the local police pulled these guys over, and told them that if they didnt get that car out of town in ten minutes they would all be thrown in jail.
So, street racers invented the cobra jet engine. :thumbsup:
