Hi all,

I have decided that that puff of blue/grey exhaust in 1st and 2nd is getting a little too obvious and new pistons and rings will be needed.

Question is this - Should I rebore to ft oversize 250 pistons (I assume they are available) or do I have a rebore to take 280 pistons?

An you rebore a 250 block to take 280 pistons?

I'ed appreciates your collective views.

Thanks

Dan
