What is the maximum rebore size for 260? The workshop manual says 60 thou and I have seen +60 pistons for sale.
My engines bores have some quite deep pitting which might just clean up with a 40 thou rebore but wondered if 40 thou wasn't enough whether boring to 60 thou would cause any reliability issues.
If not I will have to find a replacement bock or engine.
Thankyou

260 Rebore
There is a lot of information about the ford 260. Ford made the 260 and other sizes using the thinwall process to save weight. Great for a builder, not a rebuilder. The 260 can be rebored however 60 thou would be very risky. Best option is either resleeving the block or finding a replacement, easy in the USA not so were you are possibly.
