1972 350 versus 454 distributor

[D S.]

If a person has a 350 distributor (1112050) in a 1972 LS-5 engine rather than the correct 454 distributor (1112051) how would this affect performance, if at all?

Thanks,

The difference between the two is the spark advance map - vacuum and centrifugal curves.

Do you have the specs for each?

Neither is set up for "performance". Both are setup for emissions.
