1300 pistons in 1600
Hi all,
My mate and i both have 1600 engines waiting transplant into our 1300 mk1's

, so we both have spare 1300 engines.
I understand the pistons from the 1300 can be put into the 1600, to increase CRatio.
Has anyone carried this out? is it worth doing? do we need to just put 1300 pistons in 1600 job done ???
Any help much appreciated
