A nitrous 318

MY build is a standard ole 318 magnum build. Eq heads, weiand action plus, carter 625, under 230 at .050 hyd roller. BUT, I have a forged crank and some scat I beam rods. But all the stuff that would make a good strong street 318. Nothing crazy.

I am thinking about building a "stocker with intake and headers" looking engine, but with a shot of nitrous that will probably max out at around 250 for the spray. Figuring 300 on the motor (on a good day). Cam will be a custom cam, stamped summit roller rockers, and conversion studs to run chebby rockers on some EQ heads.

Planing on using ICON forged pistons, in a standard or slightly bored (.030 over, preferably .020 over), whatever it takes to clean it up if necessary and keep as much meat as possible.

Also want to use head studs and possibly main studs. Quality head gaskets, cometic most likely.

Anyway, What I am wondering about is the widened ring gap. If I am spraying those larger amounts I am under the impression that the ring gaps would be widened quite a bit. When you get to the midrange 150 to 250 nitrous power levels do the ring gaps get wider, causing street reliability or street aggrivation. Things like excessive blowby, fouled plugs. OF course I know that it will happen, just wanting to know how bad. I dont mind doing a little extra maintenance over the norm. Swapping plugs every other month is ok. Swapping plugs everytime I drive it ten miles wont do.

I always wanted to spray a motor, and right now I am in a pretty good position with the parts I have already to build a nitrous 318 that everybody always talks about but never does.

As far as a 360. I just dont want to go that route. I got another motor for the big displacement fun, really want to try a 318 challenge.
