Does anyone here know how much a standard 351 piston weighs. Need to have a new set of .060 pistons and am looking for something with close to stock weight to eliminate re-ballancing.
Has anybody seen a list showing what differn't pistons weigh.

 

Get the pistons balanced. Don't skimp, your engine will thank you for it.

 

I was thinking of ballancing the whole rotating assy. But I have rebuilt several motors using stoclk replacement pistions with no problems. But it occurs to me that .060 has to weigh more then stock and if I use anything other then cast pistions it will be off also due to piston type.

 

cast are heavier than hypers and forged. but anyways i use hypers in my mustang motor without rebalancing and it is the stock balance and bored .060 over also. no problems.

 

What kind of rpm do you turn? I don't want to be cheap but I don't want to waste money on ballancing if it is not required. I would rather invest in a head upgrade. On the other hand my truck spends alot of time at 2800 to 3200 rpm when towing so I could see where good ballance might prolong bearing slightly.

 

probably around 2100 while cruising although i don't do much of that.
