The heads have only just been reconned judging by the cleanleness of them compared with the rest of the block.Quote:

Why u ask because there is that much piston clearance there was piston slap.
I now have a delema do I rebore and fit new 20 thou rover pistons, or do I rebore to suit the pistons and crank I have already that is a 4.2 stroker in my shed? As this is my sons car that I gave him I am trying to help as a dad. I also have a brand new reconned 3.9 complete long motor sitting in my spare room ready to fit. So do I give my son the 3.9 and keep the 4.2 for my original untouched 3.5 currently running in my 89 vogue on gas that will need repowering soon.
As I said I have a delema and I dont want to be a meanie.
There is another option as well.
I also have a buick 300 crank brand new pistons and rods complete with flywheel and harmonic balancer, this will give app 4.3 with a 10 thou over standard bore.
I will have to think about it for a few days
