661 Stroker

How much taller is a 395xp piston from pin to Bottom of piston?

I don't recall. I only did this one as a favor for a friend. I have no plans to mess with anymore.

Any side by side with a 395xp piston?
Looking for a 12mm pin piston and a 661 is a 12mm.

What exactly are you looking for?

Difference in skirt length between those 2.
I need a 56mm piston with a 12mm gideon.
395 has the correct dimensions in compression height and skirt length but it's a 13mm pin.

I will measure when I get home.

I apologize for the dumb sounding question, but what does a stroker saw have over a regular ported saw? Torque?

 

[Wonkydonkey]

Bigger crank and thus a longer stroke ? iirc ? And yes more torque


A stroker engine simply aims at increasing the engine’s stroke, or the distance covered by the piston. This is achieved by using a crankshaft in which the position of the crank pin is further away from the center of axis of the crankshaft’s rotation. This increases the displacement of the engine and generates better torque, improving acceleration and resulting in the faster rotation of the wheels of a vehicle.

Or in this case the pulling of a chain.
This seems like it's gonna be a fun one.

Balls!

Basically a big-big bore 660 with improved transfers heh
That crankshaft must be like "oh *s-word here we go again"

I thought you were out of the stroking business...

All things being equal, more displacement equals more power.

Also, more displacement in a lighter saw is always nice.

Two ways to do it … 1) Big Bore or Hybrid; or,

2) Stroker.

 

[lehman live edge slab]

Except some of the aftermarket big bores make less power than an oem stock size cylinder.

 

[MustangMike]

Most of them! Some of the Hybrids run awful darn good!

OEM bored out and plated is the only way to go.

How many you got now?

How many you got now?

A couple

You?

But the bearing is smaller, so the 13mm pin will fit into the same small end with it. Perhaps you need smaller.

How convenient. A moderator that thought wrong.
