FORD > 1968 > THUNDERBIRD > 7.0L 429cid V8 > Fuel & Air > Carburetor. I pulled this motor (and C6) out of a 1970 Galaxy. Those early 429/460 engines have been purported to make much, much more.

I have a 1970 passenger car engine in 'Ice' (my '73 Grande) and I am making 500 horsepower with gobs of torque with a relatively mild build. The 1971 CJ block also had four bolt main. The 68-70 429 blocks are essentially the same except for the fact that the 429SCJ blocks for 19 had four bolt mains. These heads also come with adjustable rocker arms. The 429CJ/429SCJ/Police heads have a combustion chamber of 73.5 cc with 2.24'/1.725' valves. These heads are considered much better (for performance) than the later 72-78 heads as the later heads have much larger combustion chambers.

These heads have a combustion chamber volume of 75.8 cc and utilize Intake Valve of 2.08' and exhaust valves of 1.66'. These early heads can be identified by the casting numbers C8SZ-B, C8VE-E and D0VE-C. That does not mean the 'regular' heads are not good as they can make some serious power and TORQUE. As Tommy stated, the comparison between Mustang 429 heads and more 'run of the mill' 429 heads comes down to the fact that the Mustangs all used the 429CJ/SCJ heads.
