Timing Question, Dialing in.
I have a 1969 350/300 engine and I just replaced the original parts with the following:
Edelbrock - RPM Heads, Intake, 600 cfm RPM Carb
Crane Cams - XR-1 electronic ignition, Cam and lifters(113902). Cam specs (http://www.cranecams.com/index.php?s...02&lvl=2&prt=5)
New Timing Chain and pushrods
Plugs - R45S
Headers
So, I am trying to set my timing. I set it at 8 (factory specs), then 4. Did not have much power and vacuum was only about 10, at these settings. Also would not start when hot.
Next, I tried setting the timing when the vacuum was reading the highest. It read 15. I checked the timing and it was at about 15. I thought "yikes", but went for a test ride anyways. Wow, lots of power and seemed to run really good. Hot start seemed to not be a problem. So, with these weird setting is this just telling me that I have another problem elsewhere or with my mods, do you think that these setting are okay?
Thanks in advance -
