Hypereutuetic pistons and nitrous??

I ran a 360 with KB 191 piston and 915j heads for almost 10 years
with out problem ANY PROBLEM

I ran it for the first 3 years with out nitrous
the last 7 years I race it with 125 shot of nitrous

the cr. was at 12.33 and hade to used race fuel
when was using nitrous

the engine was as follow

1973 360 block .030 over
kb 191 piston
moly ring gap to a non nitrous engine
but was kind a on the loose side of the gap recommendation
mp .590 cam
915 j heads fully ported
holley strip dominator intake

it ran 11.50 with out nitrous and 10.48 with the 125 shot

I sold this engine to a friend and wasnt affraid

I blew the heads gasket twice but never punch a piston out
the fix was copper heads gasket if I were new I would used mls gasket instead easier to install

dont be affraid to use nitrous but use it with your brain
timing retard,good fuel,colder plugs and read them
