my friend isrunning a 383 with srp forged pistons and trying to see what my ring gap should be, the motor was built last year and i just tore it down for inspection right now the ring gaps are .0025-.0028 top ring and .0030-.0032 2nd ring does this sound about right?200-250 shot.

 

i found info doing a search.

 

Mine is .026 top and .022 second ring.

 

2nd ring should ALWAYS be bigger than the top ring.

 

Straight from JE's site, scroll down to the 2nd page of each PDF it will show you the ring gaps for each specific application:
