My wifes 1071 is having a restoration and I am getting organised for the engine rebuild.
It had the wrong block fitted but thanks to the forum I now have the correct one.
As its a worn +60 Its going to be sleeved back to standard and I really want to keep it as standard as possible so do not want to mess with compression ratio and have no interest in more power.
Does anyone have any advice on which Pistons currently available would be best quality in order to get back as close as possible to original.

1st job I would do it to sort cylinder head. Is it std? What size chambers? Then make decision based on std compression ratio.
If you are going back to std size bore, not 020, then piston selection will be more limited.
Are the small end on rods within tolerance? Some after market pistons allow the pins to be floating if rods are out of spec.

Hi , I should have said, cylinder head is completely standard .
Ref the Little ends though these will be checked and replaced if required by machine shop when all other engineering work is carried out
Its really info on available std pistons i am after

Hypertec pistons and Grant rings are perfectly fine for a std road going engine. We use them in 90% of our engines and have 0 issues.

I may have some NOS original BMC / hepolite pistons available
