Default What is the length of a series 2 rod?
Title says it all, does anyone know the length of a series 2 3800 rod?

I hit Wikipedia but it doesn't give an exact length.

Thanks!

Is a cool spec sheet. Can the torque curve be upped to follow the increase in HP with tuning? Whats it running out of @ 4400? Just a non-tuning newb question.

I find that odd. The sheet is showing 205HP, which should be factory spec for a NA. L67 should be in the 245HP range.

Sweet thanks!! That'* bore, stroke and . . . . . . I thought the rods got shorter in the series 2 because of the shorter deck height?

Thats a rod length of 4.725" for the S2 and 4.125" for the S1, are those flip flopped or am I?
