you can do a 124" for 5000.00,98" for a lot less

Won't the longer stroke make it slower revving?

I was thinking the 4" stroke was already too much.

I know this both Apples-to-oranges and well beyond the RPM capabilites of a HD Big Twin, but as a reference point for my "pissed off"...

I have engine assembly experience and really enjoy the work so I'm looking to put this together myself.

HOWEVER, I'm new to V-Twins.

That said, I like high-strung naturally aspirated engines and would like to turn up the "angry" factor on this little 88. Not really looking for a specific power figure. Really more interested in the character of the engine. Fast revving, choppy idle, wicked bark, drag pipes (regardless of their poor torque)....

I'm very flexible but right now thinking a 97-100", gear drive cams, head work, ignition, carb, etc. Not terribly interested in opening up the bottom end.

What should I do to get there?

We have a recipe for a 98" that lays down 120 hp, SAE.

Setting all other options aside and directly addressing the OPs question, a strong 98" motor can be built for $5K, if that is what he wants and plans to do all the work himself; I have done it. The total cost did not include exhaust or new T/B but did include sending crank to Hoban Brothers for T/B/W. If the OP wants a "really pissed" off motor, static CR needs to be up near 11:1 or even a bit more with CCP above 200psi, good tune and, IMHO, 2:2 exhaust like Bassani Pro Streets or Rinehart Crossbacks; much better sound than 2:1 and those two will perform as good as most 2:1 systems as long as the components play well together. The OP can expect 115-120 numbers with the right combination of parts.
