This is how the cams were selected. The grubby worksheet shows flywheel HP at Bonneville environmental conditions. The numbers in squares are the highest readings in the columns. All are for the #813 all purpose cams I used for years and they are in good shape. I just need to realign the cam gears. The hybrid-sim method was used and it considers the wave action from the exhaust system and measured cam lobe profiles. Power was optimized for the range of 7,500 to 8,500 rpm
Option 1 are the cams with the slipped cam gears. Intake centerline is 97, exhaust centerline is 89, and lobe centerline angle is 93. The piston to valve clearances are pretty tight. HP is not exceptional.
Option 2 are the cams at settings Web Cam recommended a few weeks ago. Intake centerline is 107, exhaust centerline is 103, and LCA is 105. Good results with intake lengths of 10.2 and 10.7 inches. Up to 91 HP. Primo.
Option 3 are the cam settings on the cam card, 107 intake, 105 exhaust, and LCA = 106. Good results with the same intake lengths as in Option 2.
Option 4 uses settings recommended by the Hybrid-Sim method using 10-point cam data. Intake is 96, exhaust is 112, and LCA is 104. Good low end and midrange power. Not good settings for land speed hi jinx.
Option 5 uses settings recommended by the filling-emptying method using 10-point data. 104.5 intake, 115 exhaust, and 109.8 LCA. Not exceptional.
Option 6 uses Vizard's recommendations assuming they are for 0.050 lift. Intake is 116.8, exhaust is 116.8, and of course, LCA is 116.8. Nothing exceptional here.
Conclusion. None yet. The full race cams are digitized and they will be looked at next.
