Ok, first of all, the difference between lobe separation and intake centerline is NOT the ground in advance. Lobe separation is just the degrees of separation between the intake and exhaust lobe centerlines, it has nothing to do with advance or retard of the cam grind. The 106 degree intake centerline is the reference that the rest of the cam card specs were taken at. Meaning, that when installed at 106, the IVO, IVC, EVO & EVC specs will match the cam card's given specs and the cam will operate as advertised, no matter what advance was ground into it at factory. If you want to shift the power band down, advance the cam, to shift it up, retard the cam. Intake lobe centerline should be the very first thing you check after setting TDC on your degree wheel because if that isn't set right, nothing else will read right either.

That is the correct way to find TDC, a dial indicator does not account for bearing clearance which is taken up by compression pressure !

Okay so question here cuz obviously I don't understand what I'm looking at, what is even the point of doing that the chain is attached to the gears and that's where it goes like it doesn't matter that you spin the engine and look at this degree that degree it doesn't matter ,at the end of the day the two marks got to line up Cam and crank and then the chain goes on so what are you trying to do put the tooth one tooth off I'm not understanding here?

How do know how far to adjust the piston stop? So if you get both degrees once you spin the engine.. Then adjust the piston stop again, up or down so the piston stops either down further or up higher..will you still get the same numbers once you divide the two numbers?

You didnt take into account the rocker ratio which would change your estimated valve lift after the lifter and pushrod you made. If you have 1.5 or 1.6 rocker ratio then the lift would be .009 or .010 depending on the rockers of course.

Old Griz Agree, he did not derive a number by adding .050 before peak lobe lift with .050 after peak lobe lift and dividing by 2 to get the number to compare to intake centerline which is the most common way. (Not all cam cards have a number at .006 lift)

@sterlingarcher8441

Actually you are verifying the cam makers work.. A builder already knows if he wants the cam advanced or not.. He is just checking it first to see if the cam was ground correctly. It is rare they are off but it does happen. The timing chain manufacturers are actually the main culprit of a cam being out of spec.

Degreeing is really only for high performance, competition scenarios and or checking to make sure the cam is degreed like the chart says it is. Most consumer/street grade cams are ground with advance in them making the cam just a swap part. Non street, high lift, low LSA cams ground for high rpm need degreeing so there isnt detonation while zipping down the drag strip at 150+ mph with boost or nos.

He was 13 on both sides when he rotated in both directions until he bumped the stop so if he took the piston stop out, and cranked the motor over until the pointer was at TDC on the wheel, he would also be at TDC on the piston too.. So he actually did verify TDC... But there was no reason to move the wheel to 0 (TDC) because once he knew the degree wheel was dialed in, he just needed to verify at .006 that the wheel was at 29 degrees which is what the cam card says..

he was not bringing the piston to TDC when it hit the piston stop. The piston was stopping 13 degrees short in either direction...Therefore the degree wheel was already zeroed. If he had taken the piston stop out, the degree wheel would be at zero when piston at true TDC. In effect he found TDC by coming shy of it 12.5 degrees from either direction and divided by 2. which would be zero degrees on the wheel.

First of all greetings, the video is regular, explain why ... you do not show how you should place the gears of the time chain! Must explain if they should be placed point with point, ie is placed as if a tree le cams original, in their videos is already placed the plate or disc of degrees and does not specify or show how to place the gears with the chain weather! Thank you. It would also be very helpful to publish a video in Latin Spanish, and also where it shows in a fast and effective way how to degrade a camshaft in v8 engines.

At 1:14 you say the piston will stop just before the top of the stroke (with the dead stop in). But how much before the top does it need to stop? Is this critical? Meaning, how far do you turn that bolt to protrude past the bottom of the dead stop plate? Would be very grateful if you could shed some light. Thanks.

The distance of the "stop" isn't important (within reason) as long as it remains in that position when you rotate the crank the opposite way and the piston nudges at the same stop point. The "stop" is providing two positions on the degree wheel that are easy to see and then the middle of those positions is the top of the piston movement. You could find TDC using a blank disc, as long as you mark where the piston stops in each direction and then divide the two marks. Of course using the degree wheel is needed for the rest of the process. We need to do this because the top of the piston stroke cannot be seen as the piston does not move perceptibly, for quite a few degrees of crank movement, as the crank pin passes through TDC. ... Hard to explain, hope this helps.

Or you could use the dial indicator to read when the piston is coming up. When the hand starts to spin the other way you've passed TDC. Back up past the highest reading to take up any backlash in the timing chain. Now rotate to the highest point and that is TDC.

Just a quick fact to note, when using your degree wheel to verify camshaft orientation: Many aftermarket camshaft manufacturers include a "break-in coating" on the camshaft lobes, to aid with initial wear at start-up. While the lobe profile is ground to very precise tolerances, the coating on the cam lobes is not necessarily "evenly applied". If you are noticing a "one degree" discrepancy between the specs on the Cam Card, and your degree wheel, it very well may be the result of non-uniform coating on the lobes.
