The book shows chev 4.3 L is a v6 chain driven and the valve timing is correct when the two dots line up with each other
if it is the ignition timing that you are talking about you are probably 180 degrees out in the distributor setting
no 1 piston firing lines the rotor button up at no one HT lead and not no 6
all engines regardless are timed of no piston tdc and chev engines are around the 12 degrees btdc for operation
Testimonial: "No most vs all of your 99 up models set at 0 +2 or -2 with a scanner. Mine will only set at -22"
SOURCE: 1995 escort what are the timing marks for timing belt
old fashioned method,no 1 pistonTDC remove rocker cover ,no 4 cyl valves on the rock and no 1 cyl open then look for some sort of landmark as i honestly cant remember where the marks should be.zetec the marks are on the back of the twin cams the grooves have to be horizontal with the rear caps remove the rocker cover and you will see it

there should be an acid mark (black mark) on gear, and yes cylinder #1 top dead center ps. make sure to disconnect distributor so it dont fire
SOURCE: timing belt broke on mazda 5
Think you have to put a flat bar across the back of the cam shafts same as the old ZETEC ford motors. Failing that are the vernier pullies marked with eithr O T or do they have a - or a . that line up with a position on the end of the cylinder head.
SOURCE: in replacing engine timeing belt,
no you will bend valves if not carefull. you can only turn over from crankshaft if timing marks were in correct position in first place.

I'm looking at the manual (68030 Haynes) and it shows that if you have the DOHC you make the 2 marks onthe camshafts meet in the center.
That would be at the 3 o'clock position for the left one, and 9 o'clock position for the right one. the crank sprocket and oil pump sprocket align exactly with the timing marks.
NOW, on the SOHC single cam pulley, crankshaft and oil pump pulley all are to be aligned with their index marks, centered, and the balance shaft is to be with the weighted side down to prevent vibration.
I've done the SOHC and the marks are fairly centered when instlalling. Once you've got the belt on in either engine, you should rotate the engine in the normal direction for 2 full revolutions and recheck the timing marks at all positions, readjust, rotate and recheck until set on the marks.
Good luck,
