Reboring a linered block

Post by WNX700H »

Can anyone advise what the maximum rebore is on a std linered block? Also can such a block be offset bored to 1380 ?

I wouldn,t go more than +20 on a block fitted with factory size liners . You can push them out and go to 73.5mm / 1380 but there is not room to offset the bores so you will have very little for the head gasket to seal on .

Much better to fit the thicker westwood liners , they can go out to +60

Also

Liners where fitted when they had casting blow outs in the factory so fitting liners got rid of the holes they had made in the casting

So i've been told
