hey guys,

Iam going to pick up my 351 shortblock this weekend. It has pistons that i can't use. I was wondering ifI have to balance the rotating assembly afterI install new forgies? i dont know if it has been balanced or not right now.It's not a need to do is it?

I am asking the guy now if the assembly was balanced for the setup it has now. So i read if the new pistons are a difference of up to 50 grams it should be fine, and no need for re-balancing is needed.

 

ok the crank has been balanced before, but if my pistons are within 50 grams heavier must i re-balance it??

 

Man, i would get it balanced regardless. But that is just me, i would not want to assemble that engine then find out you should have done it.

 

ok, i don't think it would cost to much.

 

ya i'dbalance it anyway, even if i was told its ok not too

 

What would you guys think it would cost?

 

at the most... $300

 

They can weight match the pistons to your old ones and press em on the rods, its a one day service. $80 +
