I have a 69 Ford Mustang 302 with a 4 barrel carburetor. The car has a 3 speed transmission. The original owner swapped the v6 for a 302 Boss motor. He left the 3 speed original transmission. Now when I drive about 45mph and up the rpm's are high at about 3000. I wanna drive this car on the freeway at 75mph. What is the cheapest way to do this? Thanks in advance!
1969 Ford Mustang Coupe 302 4barrel high rpm's at 55mph. How do I fix this?
