If Burt Cherry is still at Republic HD in Stafford and you can get the Service Manager (Burt might be the Service Manager now) to agree that Burt is the only one to work on your bike, you might swing by Republic and see if Burt is available.

103" is possible with HD parts but if 107" is the target, you will need to provide cylinders and pistons. Increasing displacement without cams and/or head work will wake things up but you are leaving a lot of performance on the table by not at least installing a set of cams that will play well with a Stage 1 103"/107" motor; head work would be plus. JMHO.
