360 HP estimate???

No, we built it as an NA motor with replacement TRW pistons/ring gaps. Then we discovered N20, we made several passes with a cheater system@125/150 hp jets and just that 1 pass with 250 jets (11.01), but we ran it on motor 90% of the time. Cheater solenoids only have a .093 orifice, so the 110n/110f jet 250 tune wasn't 250hp and the jetting on the kits was very rich back then. We encountered no problems at all with plugs (NGK7's) and we ran a lot of timing (36 total), with the 98oct leaded pump fuel we had.
If your gonna get a bit serious with it and run 200hp+tunes frequently with todays clean 5>10 smaller size fuel jet tunes, watch your timing and run 100oct fuel as its timing that kills motors with a lot of N20, then I would open your ring gaps some, otherwise I wouldn't bother if your only gonna run it every now and again with max 150hp tunes.
