I used a Port-and-polished B16 head with a 3 angle vavle job (that doesn't do crap).
I bolted it on my stock ls bottom end and it dynoed at only 175 hp at 7400 rpm. so that right there pissed me off. that i only gained 30 hp after a week of tweak and tuning and almost 1500 dollars spent. so then i went with ctr pistons, crowler straight high compression h rods, and honed out the cylinder. dyno read 192 hp at 7500 rpm. i bought crowler cams, titanium valves ( like an idiot), with retainers and keepers, and dynoed again at 196 whp at 7500. oh, i forgot, I had headers, intake, the basic boltons at the time as well as 93 octane fuel. by this time i was running around 14.8's 14'9's. then I got a MSD ignition control, air/fuel controller with manuel fuel regulator, vtec controller, 2 stage colder spark plugs (NGK), and advanced the spark about 2 degrees, with a small 50 shot of the NOS system, and dynoed at 214 whp at 7500 rpm. and thats when i ran my only 13.98 at 105 mph. Oh i wasn't using C/16 fuel during my dyno, but i did at the track.

If your friend is pulling them numbers then more power to him. My Ls stock ran 16.9 fastest run. oh and all that up there does not include the frame work.
