Need Help with "Degree Timing Tape"
Ok I bought and stuck on the Degree Timing tape on the damper, my objective is to set the total timing at 3,000 RPM. What do I use as a refference point to read the 35 degrees at 3,000 rpm. Do I use the "0" degree mark on the factory flange andline that point up to the 35 degree on the tape ?????????

yup..the 0 mark on the factory scale is used as a reference point. Rev the engine while shooting with the light and set dist so the timing reaches the desired setting. make sure to go beyond 3000 to make sure you dont get more. You want it all in by 3000, and no more after that.

Re: Need Help with "Degree Timing Tape" (Jvette73)
Sorry I disagree. You don't want to line up the 35 degree mark on the timing tape with the zero degree mark on the harmonic balancer! You want to line up the zero degree mark on the balancer WITH the zero degree mark on the timing tape, and then set your timing at full advance for 35 degrees, all in by 3000. However, that's a pretty greasy environment and the tape might end up flying off. Plus you have to be certain to get the right size tape for the size harmonic balancer you have. Installation is a little tricky.
Much better to get a Fluidamper that has timing marks all the way around. And you can install that with the engine in the car, by the way. But it's pricier. You get what you pay for.

Just as a side note: Did you find true tdc before puting the timing tape on? That is a good time to see if the damp has slipped or if your timing tap is off. Proably won't make a huge diff but if you are off by a deg or two either way you might get pinging or not all the power you can get.

He's not talking about degreeing in a cam :D . He is using a timing tape because his stock balancer only goes up to 10 degrees or so. Personally I went out and purchased an advance timing analyzer gun to avoid all the headaches of timing tapes and new balancers.

Re: Need Help with "Degree Timing Tape" (vette_c5c6)
C5C6, have you already recurved the distributor so that all your advance is in by 3,000 rpm? If not, setting timing at that rpm will not result in total occurring any sooner than it did before and you'll have a bogus setting. Many stock distributors don't achieve total advance until well past 4,000 rpm and some don't until over 5,000.
As far as using the tape, why not just mark the balancer at where you intend your total to be? Measure it's circumference, divide that figure by 10, and put a mark on the balancer that distance from the 0º mark. That will be 36º. With a little calculation you could adjust the mark to be at your goal of 35º but, considering that there's that much margin of error involved anyway, I wouldn't sweat it.

I think Bearcat mis-read your question and thought you were asking how to put the tape on the wheel. If that was your question then his response would have been correct. I mentioned 0 mark on the "scale" as a reference point for setting the timing. He responded to my reply and changed "scale" 0 to 0 mark on the "balancer". Two different things. Bearcat is certainly entitled to speak for himself but i think it obvious he just mis-read your question. No biggie..we do it now and then. :cheers: :D I was kinda vauge in my response so that might have thrown him off as well.

Re: Need Help with "Degree Timing Tape" (vette_c5c6)
Just to close this off, I did check the timing @3000 rpm and guess what It came in at 35 degrees and when I hooked the vac hose to the ported side of the carb the total timing was at 55 dgrees at 3,000 rpm. That is right on I did not have to adjust a thing. I guess the mechanic that set-up my 75 did is magic. Thank-you all for your response.
