That depends on if the TDC line on the damper are the same on both engines.

HERE is a Wiki page on the differences between the most common damper lines and tabs used on the SBC.

DETERMINING TDC will allow you to be sure the timing tab and damper are correctly indicating TDC. Once you have the engine at TDC you can put a new mark on the damper to align w/TDC on the tab you are using.

MAKE A TIMING TAPE to see what the total timing is, w/o needing to use a dial back timing light. You can also buy a timing tape, get one that matches the diameter of your damper.

THANKS..I WAS LEAD TO BELEAVE THAT THE TIMING COVER OFF THE OLD MOTOR WOULD WORK WITHOUT ANY CHANGES ALSO i AM CHANGING THE DAMPER TO A NEW ONE..SO I WILL HAVE TO THINK ABOUT THE ADVICE. ONE MORE THING. DOES THAT COVER JUST SLIP OFF OR DO YOU NEED TO REMOVE ANYTHING OTHER THEN THE DAMPER AND BOLTS.

Lose the caps, no need to shout. Im not sure what you mean by "slip off"
If you meant the timing cover to remove it you must remove the damper, remove the first five bolts on each side of the oil pan then loosen the rest and lower the oil pan. Next remove the timing cover bolts and the cover comes off. You'll want to replace the seal in the cover if you plan to reuse it.
If I were you I would use a eight inch damper with the 2 o'clock timing mark. Then I would get a chrome timing tab for eight inch balancer at the parts store that bolts on at the 2 o'clock position. Lastly I would buy a eight inch proform balancer cover. This cover can be had in many different colors. Plus it has the full timing scale on it in large size making it easy to set the base timing and full advance timing. However, if you buy the 2 o'clock chrome timing tab from the parts store you wont need to change covers.
When you get the new balancer rent the correct installation tool. The fit is supposed to be press fit tight plus it uses a bolt. Lube up the seal in the timing cover and the smooth side of the balancer. After you install the new balancer torque the bolt to 60 ft lbs of torque.
