The pistons are plenty strong.. Probe and Keith Black are other good ones for this too.
200HP nitrous shot.. You may want to blend some 110 octane unleaded race gas in with your pump gas to get
decent fuel octane.
Detonation from a lack of octane will kill and forged piston too.
@ 200 shot you want to consider the fuel octane. A 100 octane is good.
You will find it effective if when setting the valve lash cold.... to set it .006" tighter than the Hot lash spec
from the Crane cam card. When the engine warms up the lash will be just right.
Not much faith in Pro Comp products.
