Not bad but in the 60's and 70's it really could not compete against the 392 Hemi,426 Hemi and the 440 and 440 sixpack of Mopar in drag racing. Ford only built a select few cars for drag racing and there was a reason. And once The 69 Daytona and 70 Superbird came in Ford lost its spot in Nascar as well and it went even more down hill after that.
