Guide for properly lining up TDC w/distributor position
Doing the HEI conversion on my 68 Cutlass w/rebuilt untested engine. Can someone please provide a guide for lining up the engine for distributor position. I've read that #1 cylinder has to be in the compression stroke.
If this is correct, is there an simple way to tell when #1 is in the compression stroke? Is it a matter of pulling the valve cover and watching the valves move?
New to this so please bear with me.
Thanks
Dave

You can remove the valve cover ,watch the #1 intake close and then rotate engine to line up timing mark to TDC. Drop in dist. with rotor pointing to whatever wire you want to be #1 plug wire, then install wires in cap as per firing order.
Or you can remove plug, rotate engine with finger over plug hole and feel the compression.
On a clean engine, fresh VC gasket, I prefer watching the valves. I leave valve covers off when I prime the engine to see oil, then stick in dist.

Correct, you will need to set the HEI to around 20º initial. Your timing tab likely doesn't go that high, so use a dial-back timing light or mark the balancer with white paint lines for 10º, 20º, 30º, and 40º.

stik your finger in #1 lightly, turn over the engine with the dist cap off and watch the rotor, when it blows your finger where is the rotor pointing? start #1 wire there and go counterclockwise the firing order.
