Editing Determining top dead center

Have a nice day Crosley. You're correct, anyone can edit. I edited only what I wrote.

 MUST BE A SNUG PRESS-FIT 

If the engine is a short block on the stand, you can determine TDC with a strap bolted across two head bolt holes, with the strap drilled and threaded and using an adjustable bolt/nut arrangement. 

If the engine is assembled, use the method described here, using a piston stop tool. 

/MOPAR, (60 ft/lbs on a SBC, 85 ft/lbs on a BBC). 

Another risk is in stripping the threads or breaking the bolt off if you use the damper bolt to turn the engine over. If you feel resistance, or if the bolt tightens more as you attempt to turn the crankshaft- you will need to use a remote starter switch or turn the damper by hand (plugs out) or turn the flexplate/flywheel from beneath the vehicle.

 The following tool also solves this problem. Remove the crank pulley and bolt it onto the damper/balancer .............

Before starting this operation, measure the outside diameter of the damper and refer to [[How To Make A Timing Tape]] or buy a timing tape which matches the diameter of the damper. Also buy a piston stop tool. http://store.summitracing.com/egnsearch.asp?Ntk=KeywordSearch&DDS=1&searchinresults=false&y=5&N=+115&Ntt=timing+tape&x=22

If using a camshaft with more duration, you may want to increase the ignition timing lead at the crank and limit the centrifugal advance in the distributor to achieve your total ignition timing. Ignition curve kits are available to customize the centrifugal advance curve in order to limit total advance when using more advance at the crank. 

If you are using a radical cam and/or a converter that allows the engine to come up past where you would normally limit centrifugal advance (about 2800 rpm's), you may want to alter the distributor so that centrifugal advance is locked out and put your total amount of ignition advance in at the crank. Of course, the engine will not want to crank against this much ignition lead, so you will want to install a momentary switch in the coil hot wire to disable the coil while you crank the engine. Once the crank is spinning, release the button and the engine will fire normally.
