It's got a v3 onward cam belt tensioner, open deck with stock pistons . The piston crown type with the "hb" markings might help you narrow it down . As most engines I've seen have the hb markings underneath ,not on the compression side of the crown . Whv do you need to identify it ,bud ?

@GGMan Glad you got it sorted finally. The third is SRT 282 – Positive crankcase ventilation valve replacement. Interesting comment on acceleration. I'm a somewhat defensive driver and rarely us maximum acceleration, a firm right foot just seems to be a waste of good money under normal circumstances but occasionally it's needed. I've tried prior to the recall to use less than max acceleration and increase the pressure as the speed builds in an attempt to decrease the noise level associated with the CVT when the engine is max'd out. Never worked as the engine always wanted to be gu

Had mine done Break Pipes replaced ECU reprogramed for engine coils* And can't remember about the 3rd - think that was okay *What I have notice, is performance difference. I accidentally got up to 80mphs and the revs maxed out, it did not change into higher gear. Unsure if car maxed out at 80 either, as only notice speed due engine screeching at high rpms and not changing for a while. 🤔

Nice mate, I defo think its good idea to keep them standard and tidy, the parts are getting expensive now

Still really struggling to identify this block, any one got any idea.🤔 Here are a few more pics 911 does pop up any where when googling.
