Dial indicator easier.
It doesn't matter where it stops the piston as long as it hits before the piston comes to the top.There's a lot he doesn't cover. I guess his piston stop stopped the piston without any adjustments?
I'm on to using a dial indicator, and had to go back to my old one. The one with the kit is a POS that moves the needle every time you zero. The "dial" is sticky AF.
That should work.Huh? I want the piston to stop at it's highest possible point, hence TDC? No?
The dial indicator will be slightly less accurate than the piston stop, from the slack in bearing clearances etc. Very minimalChuck I misread his post thinking he was using a piston stop so I deleted my reply. Although, the same principle applies to using a dial indicator. I prefer to measure .015 before TDC and .015 after TDC and split the difference on the degree wheel.
To the OP, Google piston dwell at TDC, it will lead you down a rabbit hole…

Excellent news.IT'S ALIVE! 2.0
Yesterday was the culmination of time, hard work (for me), and money.
I primed the oil pump holding 55 psi, poured some Sunoco 93 down the carb, cranked only two/three times so fuel got to the carb and - boom - it fired right up!
20 Min 2000 RPM - the temp never went above 180. Good oil pressure, running NOTICABLY smooth compared to 1.0 attempt when I F'ed up the timing. Throttle response is very nice, no stumble.
I bled the brakes today and added PS fluid. The Flowmaster tailpipes aren't behaving well with the H pipe from tti.
The ceramic tti headers held up through the process!
Nothing major to sort out, but I do want to get the hood back on before a road test!

Yup, something that many do not think about is the dwell of the piston at just barely before and just after TDC....and it can be plotted by watching the dial indicator and the degree wheel. It might surprise some at how slow the dial indicator moves during those times of sweeping through TDC and BDC. Your slowest piston speed is at the top and bottom and the fastest is through the middle of the stroke.The dial indicator will be slightly less accurate than the piston stop, from the slack in bearing clearances etc. Very minimal
