Ring Gap, Piston To Wall Clearence, And Recomended Spark Plug To Start With.

Here is my setup:

383 Stroker (Eagle Cast Crank, Eagle I Beam Forged Rods W/ARP Cap Screws, Speed Pro 12CC Dish Pistons, Perfect Circle Moly Rings, Clevite 77 Bearings)

SLP Cold Air Induction Kit
Auminum Intake Elbow
58MM Throttle body
Elliot Intake Manifold Porting
LE2.5 Heads 54Cc Chanmer (LE3 MUNUS Bigger Valves)
236/236 @ .050 Cam
LS7 Lifters
CC Chromemoly Push Rods
1.6 X 7/16 NSA Roller Rockers
Mid-Tube PaceSetter Headers
Gutted Cat
Flowmaster Catback - 80 Series



I am not posative what I should be seting my ring rap to but I will be running a MAXUMUM of a 200 HP shot of nitrous. I Will run a 100 shot on the street a few times a week, 150 on a special day, and 200 at the track. I know nitrous use effects what ring gap should be, so with these pistson what would you recomend?

I also dont know if any of this effects piston to wall clearence. The box says minimum clearence .0010. but there is a piece of paper in the box that says that the DuroShield coating on the pistons will mess up clearence reading, it says not to measure the skirt and compensate for size.. It says to bore the cylinder to the recomened bore size listed on the lable, it also says that doing that will result in proper piston to cylinder wall clearence....Does that mean not to measure it at all???? or to measure the top?. Hmmm.

One more question, What spark plug would you use if you just build this engine?. Thanks

Call Perfect Circle and get their recommendation.
Simple as all apps are not the same.
.035 with proper heat range plug.
