Bob Tasca got so angry that the Ford brass couldn't ( & wouldn't) come up with anything better than the lowly 390, and his race team was getting spanked week after week, they raided a car in the lot (reportedly a T-Bird) for the short block, a 428, they kept the 390 gt heads and cam, and the next weekend at Epping New Hampshire, they walked over all comers!

Shortly thereafter, Ford rolled out the 68 1/2 Cobra Jets.....

I grew up 30 minutes from Tasca Ford, it was THE place to be if you were a Ford guy in the late 60's.. everyone was welcome to drop in and talk with the crews... The Cobra Jet teams all gathered there during the eastern swing.. it was Nirvana for a car crazy teenager!
