just a curiosity question, do you need to sleeve the block if you only have forged pistons? say for example i have type s pistons and forged rods, does the block still need to be sleeved?

i understand the importance of the sleeves but are they necessary if only the rods are forged?

thanks in advance

 

no
only if the pistons are forged do u wANT TO SLEVE THE BLOCK

 

k! thats what i thought, but i was just curious to know the answer
