Cams and top end - HKS 256 vs 272

[usmair]

Hi guys

I've got a stock bottom end 26 and I originally bought what I thought was used 264 cams.

When we went to put them in they turned out to be 256 cams. Due to time and money constraints I had to put them in.

That's the risk we take with used parts. I really shouldn't have in hindsight.

I'll have a Borg Warner 8374 1.05 getting tuned soon  and my goal is 500kw.

My mechanic is scaring me saying the 256 cams will dramatically limit top end and I'll be lucky to crack 450's

I wanted to get your thoughts on how much 256 will limit top end compared to say 272 HKS  drop in cams.

I'm spending over 20k on this setup and I will be extremely disappointed if I don't come close to 500 kw. 

Thoughts?

 Don't stress about it you can change the cams later if you really want without pulling the engine.

20k on a set up and you bought used cams?

 

As kiwirs4t said you can change later if need be.

yeah really regretting it, it was literally the only used part too

if its limiting top end badly i will change it but wanted to see if anyone had any experience with the topc
