vac sleeves and pistons

kenbob · Aug 8, 2018

A used parts place has a set of pistons for a vac but are 3 3/8 instead of 3 1/8. If you go with the bigger set do you have to rebore the block or are the sleeves just a little thinker.
Thanks in advance.

Sleeve are different but still fit into the same block no need to do any thing but have the correct piston to match the sleeve. one is the stock size and the other an over bore size
