When did the Ford 302 V8 engine come out?
Ford’s 302 V8 engine first appeared in the middle of the 1968 production year. Like all V8 engines, the 302 is equipped with two cylinder heads, each covering four cylinders. Within each cylinder head are eight valves. Over time, the valves may fall out of adjustment, resulting in a gradual reduction of power and fuel economy.
What is the valve size on a 1967 Ford high performance head?
Valve and port size is identical to 289-2V/4V heads. The 1967 289 High Performance head has slightly larger ports with the same valve size. The 221/260/289 combustion chamber looks like this, wrapped tightly around a pair modestly sized intake/exhaust valves.
What was the RPM of a 1969 Boss 302?
Of all the 302 engines, only the Boss had solid adjustable lifters all others had hydraulic lifters. On the distributor side of the equation, the Boss utilized a dual point, vacuum advance distributor with RPM limits of 5,950-6,050 in 1969 and 6,050-6,150 in 1970. The street 302’s and the Tunnel Port used a single point vacuum advance distributor.
When did Ford change cylinder heads and valvetrains?
Beginning May 2, 1966, Ford changed both cylinder heads and valvetrains on 289 engines. Prior to this date in production, Ford had pushrod guide holes machined into the castings. However, from May 2, 1966 on, Ford found a cheaper way to make 289 engines.
