[lian]

hi im buy a set of used ss pistons and the ownwer says the mesumnts are .5mm

for the bore how much more is that then stock \

thanks all the info i can get is the better

and i wanna get a mild port done

what are othert things im gona need to do

crank weld?

all my parts are in my profile

the bore would be 64.5mm or .020 over.

I wouldent buy used pistons when you can get a complete topend wiesco rebulid kit for like $150. Getting your crank welded would help if your running more compression than stock. It wont give you power, but it will prevent your crank from seperating.

Buy a new top end kit so you know what you got.

Wait to bore until after the porting...makes for a much better outcome.....Jim

Since we are on the topic, do you have to bore after a port job or can a hone do just fine?

same thing, you wouldn't set up a jug in a bore stand for .020, you just hone it all out.

It's a better Idea to do all your porting and then have the jugs honed to their finished size.

what problems could accur if i i went with used pistons

[lowriderb]

piston failure.. and this is what could happen if you had one.. blown cylinders/head, shot crank, broken cases, crank seals, ect..

 

its a bad idea to buy used pistons.. unless your in an extreme bind i wouldnt use them..

 

 

and even in an extreme bind i dont think i would run cast pistons if they were given to me..

ya thats not a very good idea to run used pistons ...
