| depending on your vehicle, the newer small port jobs will outperform the C-1's on a 352. There is a lot of technical reasons why, but a book could come out of that. If you are keeping it #'s correct, then the compression (or lack of it) is what is killing you. You can install the bigger valves, but will need to notch the tops of the cylinders. This should be done on most any engine built as the flowcone is always torn apart from the walls close proximity. That head has a large chamber, and the compressed mixture is not that excited as if it would be with the smaller chamber styles. The hi rod ratio of these engines need a small intake runner, head port to keep velocity up. What is the car, and intended use? |
