Wiseco 440 Pistons for 4.25 Stroke/.055 Over

GTX JOHN said

On my engine I ran Hemi length custom rods
I will remeasure everything in a day or two.
I wrote on top of box 440 with 1/2 inch stroke
I cut the deck some but i do not remember how much.
The Hemi rods are about .100 Longer ( I do not remember anymore )?

That answers that question then. A stock Hemi rod is 6.86" long, but uses a 1.031" wrist pin.

So you had custom 6.86" long Hemi rods with a 1.094" 440 size wrist pin in them?


10.725" 440 Deck Height

-6.86" Rod Length

-2.125" 1/2 the stroke on 4.25"

.055" in the hole, so you must have cut the block .055" to get it to a Zero deck height.

Do you happen to still have the rods that you had these pistons on?
