I have a chance to buy a sleeved C5 Block. It has about 100 track milesand seems to be in fairly good condition. My question is, the block is bored to 84.5mm sleeve. Will I have to get the blocked bored more when I go to put my pistons and rods in.

Thanks for any help

84.5mm is the farthest you can go so make sure that the cylinders are perfect. they may need a light hone but that is it. make sure you can get pistons that will for sure fit in the block too.

 

thanks for the reply. How can I besure i can get pistons that fit?

 

get the block measured and tell the piston company you choose you need a piston that will fit in each cylinder....you have to measure each cylinder though and get a piston specificly for that cylinder

 

Thanks for your reply man. I have a pretty good bit on knowlegde in alot of things but still a begginer when it comes to engine building.
