Finally some Cam Degree Numbers - Now what?
I'm back, and have no idea what I am supposed to make out of the numbers. Here they are. If you recall I have been reluctant to pull the heads, and it was suggested I degree the exhaust valve on number one.
Reconfirmed TDC and very repeatable. The info I found on the 77B: Int and Exh durations 260* or 220* at .050" Lobe separation 111*, lift .325* Lash .014". I got: .050" open at 148* Exhaust starts to open @ 120.5* Exhaust starts to close @ 348.5* Exhaust is closed at 9* ATDC Exhaust Lash is .014" Is this enough to get a feel for the cam location? What else need I do. Exhaust centerline? |
