The KB kit running 9psi intercolled is right at 5K now would that be cheaper than goin N/A and parting and polishing along with boring and buying cams and heads? I know that the trick flow heads are like 2K and the comp cams I was looking at are 600 I don't know what it would cost for a machine shop to bore my motor out so has anyone done this?? and for installation I know that would be pretty pricey?? Also has anyone bought the KB 2.1 and installed it themselves??
