piston differences question

[davenichole]

i have several blaster pistons laying around that all pretty much look the same, except for this one here on the left. any idea in what application that one would be used for? the ports, obviously are bigger and higher. also, the design around the wrist pin is different.

I could be wrong...But it looks to be a "Vito's 240 cast piston".
I have a "piston map" of that piston.

 

[joeak47]

On second thought...It looks to be forged. Perhaps its a "Vito's forged "super stock"?
The vitos pistons have the windows cut higher in the piston.

 

[davenichole]

well, no. it is only a 68mm. not the 72mm of a 240.

 

[joeak47]

Vito's forged super stock pistons come in 68.00 and 68.25MM...

Thats what it looks like to me.

Does it have the "exhaust port" relief cut on the piston crown?

vitos also have the wrist pin cut down like the pic shown i am going to have to agree with u here

Do you have a picture from the "top"?

that it does. whats the purpose of the 'windows" being moved higher? does that work on a otherwise stock engine or does it require other mods like a stroker crank or long rod or cylinder port work?

The piston on the left looks like a forged variety to me.

The piston on the right is a Wiseco. The one on the left is a Vito's super stock.
