Re: Camshaft sizes
The most common size is 21-3/8" long, and they seem to work the best.
Honestly, you need to evaluate what you want to do with the engine, the modifications (current and planned), and how you want the vehicle to behave. Then you can select a cam profile best suited to the application. The transmission, axle ratio, weight, fuel use, your driving style, and the induction and exhaust systems will all drive the cam choice.

Re: Camshaft sizes
Im just doing exhaust, rear gears (3.90 to 4.10) then a programmer to set max power and decent fuel economy (11-13)

Re: Camshaft sizes
Will this be carbed? Automatic? Higher stall RPM converter?
If you are staying with TPI, 3.90-4.10 gearing may be a little steep. You'd be in the sweet spot for torque/power for all of about 40 feet. Well, maybe that's a bit of an exaggeration, but tall gears are not all that well suited to TPI. And cam lobes that work well with engines in front of tall gears typically don't work well with TPI. With TPI, even 3.73s are a bit of a stretch. You can still choose a cam that will maximize the lower RPM power of TPI.
If the induction system is changing, the gear change would make more sense. At that point, a different cam profile would also make sense.
Up to that point, there are some pretty good cam selections for an L98.
