I'm not aware of any requirement to do anything to the engine, other than bore to suit. But while you're about it, a balance might be worthwhile (but, as I said, not essential AFAIK).

Hi all,

Thanks for the offer for the pistons but I've managed to find Weisco forgies for $900 new from someone... with rings, etc... Never been used..

I've done a lot of research lately and have noticed a bit of a common trend in opinions in regards to Aries pistons.. I've been told that they are a bit louder then other forgies.. I mean, all forgies have the potential to knock when cold but they are a lot better now with the silicon compound... aries don't seem to have as good a reputation from what I've heard...

Anyone else heard similar?

P.S... if you're going to put new pistons in, you'd be stupid not to balance and square deck the block while it's apart..

I'm in the process of getting all of this done at the moment. The block is in as we speak.. Torque plate boring is the way to go.... shot-peening the rods, new rod bolts as well caus they stretch...

My crank is just getting a polish caus it doesn't need machining..

Reason why these pistons you have for sale are no good is because I'm not boring it out that much.. 1mm is 40 thou I think, I'm only going 20 thou.. (.5mm)
