David Vizard, Uncle Tony's garage, Unity motorsport. Mission impossible Dodge 302 Head porting

OK wow!

Seeing what I see here it sure looks like David chose the Heavy 645 Bushed Floater Rod for the 340s.

It has the wider neck just like the 645 press fit here on the right.

The left rod is the Lightest Mopar Rod, the 782 with the narrower neck.

Pretty obvious to see with this comparison picture.

So David started with the heaviest rod to do his grinding lightening work.

David's 318 build rod here:

Looks and shape, looks like the heavy 645 in the top picture on the right.

Interesting . . .

Seems the lighter 782 rod has a better advantage, and it is lighter to begin with before any grinding.

I think he's doing it because he can. Other than time, it costs next to nothing. It will lighten the rod a bit but not really enough to make a horsepower difference. It's like removing casting flash on the block, it's supposed to make the metal stronger but when was the last time you saw a Mopar rod break especially along the middle.
