From: Leeds - It was 562.4bhp@28psi on Optimax, How much closer to 600 with race fuel and a bigger turbo?
to run something like 272 - 276 may require different springs etc.
John banks is using sti5 cams with good results.

Kurt,
There is nothing like good or bad for cams (or heads, or turbos, or........) It all depends on your wishes! An engine has to be build to fullfill your wishes. In my opinion anything above 400 HP is too much for a std. US STi block (for reliability), so US STi cams will do fine. (these cams also suit the 7000 RPM redline which should be about the limit for this engine to keep it in one piece)
If you change the internals and raise the rev limit, you could go for longer duration cams, etc.
Just my 2c.
Mark.

EMS, didn't you have some photos of vernier wheels a while ago. Did you do some work on gas flowing heads about 6/12 ?
I'm building an engine without the variable cam system I will not be able to use the US STI cams I think
