I think what your asking is where should # 1 plug wire be for firing order? #1 cylinder at top dead center (TDC) on compression stroke. Distributor rotor should be pointing at # 1 plug wire. If it's 180 degrees out, you might be on exhaust stroke. Thumb over spark plug hole will let you know what stroke your on.

    If you have rocker cover/valve cover off already , all you need to do is look at the valves above #1 cylinder . Both valves should be shut, and piston at TDC with timing mark at front pulley aligned with indicator on timing cover at TDC. If cover not off, use compression tester to confirm piston is on compression stroke.

Need firing order diagram for a 1970 302 boss motor. What cylinders are number what? It is a Torino but you do not have that listed below.

Pistons 1-2-3-4 are front to back on the passenger side of the engine and 5-6-7-8 are front to back on driver's side. The distributor turns counter clockwise and #1 piston is the first on the driver's side of the clip at the back of the cap. The 2 clips should be at 12 o'clock and 6 o'clock, standing at the front of the car. The firing order should be 1-5-4-2-6-3-7-8. I got this from Chiltons. Hope this helps.

Installing distibitor 1997 5.7vortec

with # 1 piston (front piston on drivers side) on tdc compression stroke place distributor in pointing at the front of the drivers front tire as it drops in it should point roughly at the # 1 piston as it rotates clockwise as it drops in , the cam gears have to mesh so dont force it . if it wont drop into place try a small bump of the starter while applying light pressure down on the dist.it should drop into place and then lock it down a bit . get #1 piston back on tdc compression stroke make sure the power wire is off the dist . the big red 1..you dont want it having spark yet. if it goes into place then set your cap and wires back in and time it with timing light .remove vacum hose from vacum can on side of dist and plug the hose off then use timing light and set to what factory says , usually between 4-8 degrees btdc. 1-3-5-7 piston numbers front to back drivers side ///// 2-4-6-8 front to back on pass side firing order is 1-8-4-3-6-5-7-2 and the dist should have #1 pointing at the drivers front corner of engine. start # 1 plug wire there and work clockwise next spot clockwise on dist is #8 plug wire and so on.. good luck
