A look at the Manley stroker pistions,
Part # 608005c-4


I had a customer drop off a set for a build. Manley always seems to have a pretty piece in the box.

The box claims that that the pistons weigh in at 296-297g

Out of the box they were appox. a gram heavy 297-298g .8g to be exact

The wrist pins were close .2g from high to low

Now placing the wrist pins in the piston, I was able to get .7g from high to low.

Not much needed for balancing on this set.
The light piston and wrist pin weighed in at 395.1g

Some slight polishing brought all 4 pistons to 395.1g

The piston diameter was close too I found a mere .0002 variance.

The spec sheet.

Back in the box till they are ready to be assembled on the rods.

Looks gorgeous, I have a similar setup, and my machinist (old school v-8 guy) was very impressed with them.

What snail spool said goes the same for me.

I am not impressed. They are far to light and thin to be able to do anything serious with. When will people understand lightweight and forced induction do not go hand in hand.

Forged...The point is to match the weight of each piston and rod with each other......

I bought some Wiseco pistons some years back with the same results. Apparantly they had under gone some changes in quality control and raise the price a bit. Every piston weighed the exact same and was the same diameter. I gave my block to my old machinist with the pistons in a box(so he could bore the cylinders specifically for each piston) and he bored it and gave me the box back with un-marked pistons, saying there was no need to number the pistons, they were all exactly the same. That was in 2008. I still have the motor.
