It seems to me using a piston stop would be an easier way to find TDC; you only need to pull the #1 spark plug. Bring that piston up to the 0 degree mark on the balancer. Adjust the stop to touch the piston top. Reverse the engine rotation until the piston hits the stop from the other direction. See if the timing pointer hits the 0 degree mark again. Even if it doesn't, correct TDC will be half way in between.

I set the total timing on my 68 327/300 to 36 total with the vacume pluged ,my inital is now at 17 the car seems to be running very good. my question is with stock springs I am all in at 1700 rpm.Should i try and find heaver springs or different weights to get it all in a little later and what differance would it make.Thanks for all advice

It's not the weights or the springs, there's little bushings underneath that limit the amount of advance that can be achieved. Right now you're only getting 19*, that's not very much.

Yeah, this is the right way to find TDC with an installed engine - it's not possible to get any sort of reasonable accuracy any other way.
