Hey guys,
I am having a 2270 built, 78mmx96mm. We are using the 163/86b webcam and 2.0l heads. Dellorto 45s and msds headers. I am trying to decide on the right compression. The build is aimed at aggresive street use. I want to have as much power as possible and not have to run an external oil cooler or have any problems with detonation on 93/4 octane gas. I have heard anything from 8.5:1 to 9.5:1. Please let me know your thoughts. Thanks, Andrew |

I decided on the 45s based on some research done here on the forum.
I consulted the engine builder as well who thought they would work fine, or that they could be configured to work very well. He did not think they would be too big for the displacement. most 2270 kits suggest EMPI 44s no? |
