Had motor rebuilt, putting back together, marked # 1 position on dist. when reinstalling does not line up exactly on mark. No adjustment on dist. Does computer adjust for this?

Yes - The computer will adjust itself.
Just be sure the #1 cylinder is at TDC of the compression stroke when installing the dizzy.


From the FSM...
The distributor is correctly installed when:
" the rotor is pointed at the 3 o'clock position
(2.5L engine), or at the 5 o'clock position (4.OL
engine).
" the plastic alignment pin (or pin punch tool) is
still installed to distributor.
" the number 1 cylinder piston is set at top dead
center (TDC) (compression stroke) .
" the centerline of the slot at the base of the distributor
is aligned to the centerline of the distributor
hold-down bolt hole on the engine. In this position,
the hold-down bolt should easily pass through the
slot and into the engine.
No adjustments are necessary. Proceed to next
step.
(12) Install the distributor hold-down clamp and
bolt. Tighten the bolt to 23 N-m (17 ft. lbs .) torque.
(13) Remove the pin punch tool from the distributor.
Or, if the plastic alignment pin was used, remove
it straight down from the bottom of the distributor.
Discard plastic pin.
(14) If removed, install the camshaft position sensor
to the distributor. Align the wiring harness grommet
to the notch in the distributor housing .
(15) Install the rotor.
CAUTION: If the distributor cap is incorrectly positioned
on distributor housing, the cap or rotor may
be damaged when engine is started.
(16) Install the distributor cap. Tighten distributor
cap hold-down screws to 3 N-m (26 in. lbs.) torque.

(17) If removed, install the spark plug cables to
the distributor cap. For proper firing order, refer to
the Specifications section at the end of this group.
See Engine Firing Order.
(18) Connect the distributor wiring harness to the
main engine harness .
(19) Connect battery cable to battery.

Motor has to be at top dead center of the number one cylinder. On the harmonic ballancer the bottom pulley , there are timing marks. Set to -0- on the compression stroke of the number one cylinder. If the dist still wont line up to what you want. Look down the hole , you will see a gear with a slot in it for the end of the dist to engage. You can reach down there with a long screw driver and rotate that slot to anywhere you want. If its a hexagon you will have to find some thing to turn it with. Once you get the dist seated and snugged down, you may have a gizmo called a shunt that you will unplug to adjust to the right timing. Some of the newer units just bolt down and like you said the pewter will do it for you. FjR68

Have #1 cyl. at TDC of compression stroke so I'll put dist. in as close as I can get it and let the computer do the rest. Thanks let u know how I make out.
