Well, your looking at about $5500 for the KB for about 390-400RWHP..or the mongoose kit with the novi 2000 for about 3700 (like stated above) and pull at least 350RWHP and easily as high as 375...If you take it to Tim at MPH, he could probably get that non intercooled novi to push just as much power as the intercooled KB....and on the KB, I hear of people blowing their engines all the time with them, probably due to the fact that at almost anytime you hit it its making 9PSI (or whatever you have it pullied for) until you let off the gas...the novi makes peak boost at whatever the highest RPM you shift at...as in the higher you shift, the more boost it will make(different pullies will increase or decrease boost at any given RPM) ...but with a stock block I wouldnt go over 5500RPMs just to be safe.JMO BTW.
