Yes. But I would roll it around and get the timing mark on the damper where you want the initial timing. Say, 16 BTDC or whatever. Then before you drop in the dist. look at the clocking of the intermediate shaft down in the dist. hole. It should be very close to North and South in the engine. If it's not, make it so. Take a big flat head screwdriver and twist it CCW and it should disengage from the cam gear and you can rotate it so when it drops back down the slot in the gear is parallel with the cam. The gear will turn the intermediate shaft when it goes in so you have to be "in front" of where you will end up. Mark the #1 terminal on the dist. cap down to the body of the dist. Drop the dist. in without the cap. Make the rotor point at your mark and loosely tighten the dist. clamp. Put the cap on and check 1-8-4-3-6-5-7-2 COUNTER clockwise on a big block. On a factory type dist. with a vacuum can, the can should point up towards the intake and #1 should be close to about the 5 o'clock position when looking from the pass. side of car. This is a big block?
