Ill get a pic up of mine in 2 secs.

I got mine direct brand new from Mountune 2 years ago so they aint copies or anything like that.

I have had issues with my block cracking in the cylinder walls and after closer inspection my block seems to have thiner walls than two other older 200 blocks we looked at.

I have ran my block for over 2 years now at various power levels and only really had the prob on 500 ATW spec which i guess is similar to most peoples 600 bhp engines as these are measure on the engine dyno, so anything under this power I would say they are ok.

Any other questions?
