Re: gap for plugs, for a stroker motor........................ Well...my Haynes says that LS1s were factory gaped at 0.060".....
I'm running 0.050" in my 11.1:1 compression H/C LS1 and that seems to be working for me........
I'm interested to see what people say (more knowledge). As I understand it:
People go with less gap as HP increases. But that’s usually with power adders like FI or Nitrous (higher cylinder pressures) right?
With increased CI, your not really increasing the cylinder pressure, you’re just giving more piston area (or stroke/leverage) for the given pressure to work against.
(my head hurts now.... 
)

(my head hurts now.... ) Would that make it run like crap?
No power adders at all, just N/A.

Re: gap for plugs, for a stroker motor........................ I'm really not sure......I would think it would loose hp if you got the gap too small....
the idea is to get the most gap possible (more spark) without getting it too far (spark gets "blown" out by cylinder pressure)...

Re: gap for plugs, for a stroker motor........................ The reason I'm asking this is because the second I changed my plugs and wires last week the motor os surging like crazy every time I come to a stop. It goes from 400 to 1,500 rpm and sometimes will stall on me.
And while cruising steady at about 40mph is will start to miss and jerk back and forth till I increase throttle, then it will smooth out. Someone told me at higher rpm's the energy will be enough to keep the spark from missing, but down low it will miss.
I gapped them to .045. TR6's.
Maybe I should pull them and go to maybe .053 or something?????

TR6's can't be gapped more than .045. I put the old plugs back in (TR55's) gapped to .050 and the car runs and idles like a dream.
