We have several Genesis blocks already running on the street with great results. They have no over heating issues and run great. Matter of fact one customers has a 4.310 bore block that he says he has a hard time getting to run at 160 degrees. This engine is in a 67 Fairlane that is street driven all the time. If the people building the engine checks the block out that they are using properly and machine it correctly you have no problems.
I would rather have one of these blocks 3 to1 over the thin wall blocks that Ford produced. They are much stronger and can be bored much bigger. I have more coming in soon. Bring your FE up to 2004 with current parts that are much better than the original stuff. Good Luck, Keith Craft
