hi all hope you can help
I'm building my block back up Cosworth 205 block on a 0.5 over bore with mahle pistons so I've had the engine shop look over the block
and they have said the bore clearance on cylinder 2 3 4 is 4tho but number one is 4.5tho at the bottom and near 5 tho at the top he said this will be fine at that but I would like to hear what you think before I start to build
get an second opinion first
thanks Chris
