theres about to be a 2nd stock blower lsj to break 300whp! first ride tonight on rebuilt motor (snapped a lifter) went from stock to CAI, dual pass opt b, h/e, full 3" exhaust catless, meth 75/25, p&p head w/ supertech valvetrain. stock cams, i/m, bottom end, blower, tranny. had injectors go static just before 6200rpm. friday the car will have gm stage 2 pulley and injectors with a full tune, no dyno numbers yet tho. hopefully by end of summer car will have 2.7/2.6 pulley with a tb spacer and/or blower spacer tapped for meth... thats when the car is hoping to see 300whp+

The timing on my car for that dyno was only 11* :/ . I had my timing increased and I'll try and dyno again asap. Big difference now, I may have it increased even more.
