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 |

Head temps around 325F and AFR avg around 12.8-13.2. I also had Tangerine headers and an external oil cooler, btw. But I think 45's might be a bit big. Anyone else have thoughts on that? |
