I found out the other day the block which I not long ago rebuilt is actually 40thou over (it's getting rebuilt again by the pro's this time lol).....but as I was told it was std bore when I bought it, I put std rings on the pistons and never bothered to measure. The gaps did look a bit big but figured it just must be right as I haven't done many b4 so don't have anything to compare them too.

My motor still made 174rwkw. I guess with smaller rings the compression would of been down a bit and would explain why it did smoke a bit. Does that sound right? So really it would of made more power if I used the correct rings?

174kw in what is the same as having a knackered motor is pretty decent!

There was no markings on the pistons which is another reason I just assumed they were std lol.
