What's the problem, if you can do a single cylinder engine you can do a V8, just more bits to lose.![Smile :) :)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)

Still fighting with the next....Talking of which, one piston down and ...?

Replacement Con Rods have arrived.....looking sexy, test fitted to original pistons, perfect. Gudgeon Pins have been measured as have the piston pin holes, and after a quick clean with a bit of Scotch Brite to get the oxidation off, they are a beautiful fit with velvet smooth-ness....you know that silky machine fit...!!!

Why not fit replacement pistons and rings as well?
you can get them cheaper, but i would have done with a rebore£240.00 a set maybe the stumbling block.![]()
I hope you have weighed them, don't want it running uneven.Still fighting with the next....

To true Tony, I had to get high comp pistons from Israel for the E type, all that was available in this country was low comp.I just gave Rimmers price James. Suppose you could get them from an engine shop. But the days are long gone around here when you could go into Hepolite House on Brook St and get them or loose single rings over the counter. And they WHOULD be in stock unlike today were you get stuff a week on Thursday..
im not doubting anyones skills in measuring but where they are taken matters, very top of swept area at 90 degrees to crank is the greatest wear area, i usually fit h/c pistons (9.35)in replacement of l/c (8.13) unless insisted not toThe bore was measured in 3 axis within the top 20mm of the bore....all readings the same....and our LHE builds, re-builds and re-bores Aircraft jacks capable of 200+ Tonnes under test.....pressures inside are measured in the 10's of thousand PSI, so his bore measuring skills I would match against anyones!
So it is possible to use higher compression pistons in the engine with little detrimental effect??
I am always keen to learn from the more learned...
8.13 -1 is what you have now, 9.35 - 1 will be flat tops.I may have sourced a set of pistons..
So with the options of being 8.13:1 or 9.35:1 compression ratio.
Yep, the CR is stamped on the block....reading JM's posts, he seems to suggest that the high CR pistons would be a better option!
Thoughts from the floor so Adam can create an informed choice!
