Cyl no 1 is easy :-).. timing marks  algin them and make sure ya got
pressure at spark plug hole with finger wilst some one turns it over by hand
(I know not the best way..)  then the other cyl are 120deg ay in the firing
order..

	Hope no one minds, but I came to the sudden realization that I don't
know
	how to diagnose cars.  And how can I expect to 'performance tune' if
I
	can't even get a stock car back to stock? (hence the very weak gmecm
	tie-in).  O.K., I'm going to try to do a leak down test on an 1989
Chevy
	Beretta, V-6, manual trans, Front Wheel Drive.  I looked in the
service
	manual I bought from a dealer, and couldn't find directions on how
to find
	top dead center.  Any suggestions?  If no other ideas, I plan on
taking
	the valve covers off and moving the crank until I see both intake
and
	exhaust valves closed, and not moving.  I imagine if I don't get
exactly
	top dead center, filling the cylinder with compressed air is going
to make
	it move down, so I'll keep my fingers away from the belt, and mabe
see if
	I can 'lock' the crank from moving.
	Thanks for your time,
