Advice Needed - Can't Start Rebuilt 273

I read what you did and this is {{{what you wrote.}}}AND WHATS WRONG

1)I pulled the left valve cover and found TDC for #1 by watching the intake valve just start to open. Then I backed up the crank a bit to get the timing mark right at zero.

2)At TDC for #1 cylinder, there is some preload on the exhaust valve. As I understand it, that should NOT be the case, right?

THE REASON YOU HAVE PRELOAD ON THE EXHAUST VALVE IS BECAUSE WHEN YOU WATCHED THE INTAKE VALVE OPEN AND THEN BACKED THE MOTOR UP TO WHAT YOU THOUGHT WAS TOP DEAD CENTER ,YOU ARE ACTUALLY IN BETWEEN THE INTAKE AND EXHAUST STROKE FOR THE ENGINE.
THINK ABOUT IT IN THE RIGHT ORDER FIRST

POWER \ EXHAUST \INTAKE\COMPRESSION

TOP DEAD CENTER IS AT THE BEGINING OF THE POWER STROKE AND THE MARK ON THE DAMPER ,WILL LINE UP ON YOUR TIMING TAB.,
BUT IT ALSO LINES UP ,ONE MORE TIME ,WHEN IN BETWEEN THE EXHAUST AND INTAKE STROKE.
(((THIS HAPPENS TWICE )))I THINK YOU BACKED IT UP TO WHAT YOU THOUGHT WAS TOP DEAD CENTER ,BUT ARE REALLY IN BETWEEN THE EXHAUST AND INTAKE STROKE.
THIS IS WHY YOU HAVE PRELOAD ON YOUR EXHAUST VALVE.

1)VALVES ARE CLOSED ON THE POWER STROKE
2)THE EXHAUST VALVE OPENS NEXT <<<< PRELOAD ON VALVE

:hello2:YOUR IN BETWEEN THE INTAKE AND EXHAUST STROKE

3)THE INTAKE VALVE OPENS
4)THE NEXT STROKE IS THE COMPRESSION STROKE {{ VALVES CLOSED}}

DO THE SAME THING YOU DID BEFORE BUT DONT BACK THE MOTOR UP , KEEP GOING 90 MORE DEGREES CLOCKWISE TILL TOP DEAD CENTER.

THEN CHECK THE DISTRIBUTOR AND MAKE SURE IT'S ON #1 ONE CYLINDER ON THE CAP.
PUT THE WIRES ON GOING CLOCKWISE [ 1-8-4-3-6-5-7-2-}

:thumrigh: DOUBLE CHECK THAT YOU DID THIS RIGHT (WHEN YOUR ALL DONE WITH THE WIRES AND DISTRIBUTOR )BY ROTATING THE ENGINE OVER BY HAND AND WATCHING THE EXHAUST VALVE \\\ IT WILL BE THE FIRST VALVE TO OPEN AFTER THE POWER STROKE
,AND SINCE THE WIRES WERE PUT ON RIGHT ,AND THE DISTRIBUTOR WAS INSTALLED CORRECTLY, IT SOULD FIRE UP.

GOOD LUCK:salute:
