hmm. 10+ years as a member of Stallion Racing as Research and Developmental specialist helps to see where
things hold to certain limits as long as the customer signs the waiver to hold me harmless
I guess you need to define the starting point to define weak. 230 ish to the rear tire stock 5 speed and adding 9 lbs of KB isn't exactly weak on an otherwise bone stock car. Remember this is the 2v we speak of, not a 3 or 4V. I've seen more centrifugal blower hit 375 plus and even as much as low 500s with head work, cams etc. but it takes longer to build up boost, unlike having 9psi at 2500 rpm w/ the KB
The powdered metal rods are the weak link in the mods. I do know of a handful of boys roaming the streets on 500rwhp on stock bottom-end 2v blocks. It can be done. It depends on how many times you plan to use all of that boost.
Seeing that I can't give away customer info due to being sued, there are plenty of guys right on here making over 500 rwhp 5L blocks

You have to remember that not all dyno numbers are created equal; air temp, baro, elevation an so forth all factor in and this is before we even begin to look at the platform.
