BBC 460 cu. in., 950 Holley HP, edelbrock victor jr, edelbrock 355 cnc heads, 10.65:1, .600/ .630 lift solid roller, 245 duration @ .050. Heads are new and raised my compression from 10.25 to 10.65.
Ron,
When I retarded the timing my idle rpm didn't change much so I never raised the idle speed and therefor uncovered the transfer slot. I agree and was originally taught for racing purposes more timing at idle is better but don't you agree for the street you will need a curve in order to prevent detonation during normal driving on the street.
