Basically the ports( 4 venturi heads)(4V ) were hugh by factory standards and a lot of horsepower could be had at very high rpms . The 2 venturi heads (2V)were too restrictive by the same measures. Because the 351C engines were used in mustangs ( and others ) the factory did not want them revving to 7000 plus rpm where the ports started to work well. You could a few years ago buy a port plate that pretty much covered up about a third of the port ( looked similar to the jb welded port). Much better torque and horsepower was the result.

The Australians Built a new cyl head (called a 3V )that took the best properties of the 2 heads .

Some one needs to try it on the 229 and let us know.

I had a big block 351 Cleveland in a 73 Ford long bed Ranger custom cab. It was backed by a C6 auto transmission and a 9-inch positive traction rear axle.
