what's the most horse power that can be squeezed out of a stock non modded SRT-4 head.

I have seen 525whp out of a stock head/stock cams big turbo car

Good info any details on the rest of that build? Boost? etc?

I remember when the DCR Hot Rod was running, they had some sort of failure that required switching heads. Swapped on a stock head and ran near identical times and minimal loss of MPH(maybe 5mph or so). Depends on who's point of view if thats good or bad though.

Been too long since I looked at this stuff... Forgot whether this was SRT or NA
