    fluid moving past an orifice CAN produce a vacuum as molecules get dragged into the airstream. I believe the Dr said it had a check valve to keep from going the wrong direction when I was picking his brain on the matter.

        Ahh, if it is a venturi device then that makes sense.  That didn't occur to me.  I would be curious to see with a gauge or manometer tube to see how much vacuum it produces at different engine speeds/loads.

          Got the crank sprocket off.

          The carnage:

            is it a dual row chain for the cams, or is that sprocket strictly only for the oil pump?

              One row is for the pump the other for the timing.

              I'm glad I noticed these rounded off teeth. Worse than expected.

                Is that normal tooth wear for those? or did something cause it to wear more severely?

                  Not normal at all. The chain flopping around when the pump snapped had to round them off.

                      This is soo ghetto. hahaha. Why do this when you can go to concours and ask todd or burger to borrow them for the weekend or such. Not like they use them at the dealer everyday.

                          I will be getting the VAC harmonic dampener. I tried to order it today but they didn't have time to process my order. I called twice. Great products, phones... not so much.

                            Is anyone familiar with timing the S52 that could swing by my house and make sure I have it correct? Willing to pay $$$

                                      The headache is worth the outcome! I got a taste of the power and it is addicting. The only car that got me was that fox body 5.0 that was turbocharged and probably built. He got the jump on me and still didn't pull more than one car on me. Soon. Soon.

                                          Finally got into the garage.

                                          With my JB racing flywheel there is no flywheel lock hole so I just need to keep an eye on the tdc mark.

                                          The cam locking tool that I got was a little too narrow. So I'm going to watch that with my eye too. Sketch yes. I need to get this on the road.

                                          Got the timing set up and just need to torque down the exhaust cam bolts while there is torque on the tensioner.

                                          Then is is all down hill from there.
