Swing Arm Length

[Boomin Blaster]

I am looking into asphalt racing my blaster. Currently it is stock, but I plan on doing V-Force 3 reeds, RDZ Dragpipe, 32mm carb, alky, port and polishing. How long of a swing arm would I need to be able to keep the wheels on the ground with these mods. Also plan on running 22" tires and a 14/38 sprocket set. I am 5'10" and 140lbs.

A common length is +4" it gives it a little bit longer wheelbase, but if you want to ride wheelies, still very possible. If you are going to strictly drag, Im not sure, anything over +4 starts to look funny, and isn't really needed unless major hillclimbing or draging.
