Deck Height - One Cylinder is different, is this okay? Plus 7.3 compression ratio?

[QUOTE="cunning plan, post: 603429, member: 4090"] Thanks for replying Abel :D Interesting that it produces more power, is that because the spark can be timed to fire earlier in the cycle, almost creating a 'bounce'? Although, if you are using 7:3, then I will use it! :lol: :cry: this is something I was worried about. Brilliant, I will follow this to try and figure out what is the issue. I have also bought a DTI / Dial Indicator to help with identifying the TDC as I was going by feel and by taking a couple of measurements, using the average to try and get it right, but an indicator should take the guess work out and make it more accurate. :? Taking the barrels apart again does provide an opportunity to weigh the pistons I guess, like I said on the other thread you replied to, I had forgotten to do that. I did forget to mention in the engine spec above, that I am using the used Crank and Con-Rods from the engine, they are not new apart from new main bearings, so it is possible that the crank is not perfect. [b]IFFF[/b] it is the rods, I really, really do not want to take the case apart again. :cry: :sad0049: At that point, as a solution for this [i]'lazy engine that is a merge of new and old parts'[/i], could I just buy x3 wider shims to bring cylinders 1, 2 and 3 down to 7.3:1, along with a thinner shim to bring cylinder 4 down to the same? In my mind, that should match all 4 cylinders together and it should ensure the barrels are aligned for a good seal to the head, right? :Poke: [/QUOTE]
