Need a plan - component selection for restoring 68 340 that runs on 91 oct
Roger. I'm gonna guess the .050" lift intake closing angle was put in. The 'advertised' intake closing angle needs to be put in for that calculator.
And you might as well throw in some extra, to compensate for the time from advertised to no-longer bleeding-pressure, cuz .008, or .006 or .004 ain't closed yet. And few there are that know how much to add. I sure don't.........
I thought I was doing pretty good until
Wyrmrider showed up. Of course I knew about that ramp, but I had no idea it was so large, nor varied so much. Yeah that was a humbling moment.
I first noticed the discrepency in 1999,by accident,during a LeakDown test. When the TDC piston flipped backwards and the pressure blew off,and the Leakpoint was way off scale. I reduced the test-pressure and snuck up on the advertised ICA. Crimminy, I thought, My cam is in wrong; how is that possible? It wasn't off.
But there is a silver lining to this.
