Timing Mark Options
I need something to rig up or buy for my LT1. Is anything available that works on a SBC and our motors? Tired of struggling with finding TDC on #1 every time I move the cam sensor.

Pretty much going to have to make something. I plan on making a small plate that will bolt to the timing cover then tap those holes to line up with an adjustable sbc pointer. Some people have said certain holes actually line up but I've not checked to see if it's true or not

I bought a cheesy adjustable Mr Gasket one from the parts store and gorilla glued it to the opti cap. I used a white zip tie to extend it over the belt and allow belt changes.
I can post pics tomorrow.Last edited by 96LT1355Z28; 04-25-2016 at 10:19 PM.

I have the gmpp opti block off plate which has a timing marker on it. Not the most accurate and it's off by about 7 degrees but it works.

The hub isn't keyed, so technically it can move a bit and throw the numbers off, unless you have a keyed stroker crank with a keyed balancer.

Here's what I made from this pointer, after doing some trimming I glued it to the opti cap and used a zip tie to extend it. The zip tie gets it closer to the balancer and flexes which still allows the belt to be removed.
