The LBZ rods are ambidextrious. each one will work eaither way. and i just took pics and sent them to paul showing a offset on the big end of the rod instead of the small end, that makes sence now. :hug:
First aluminum duramax rod!!

harmonics can creat a audiable noise in a high performance engine, and aluminum absorbs sound much better than steel,by absorbing impact transfer to the crank hence lessening harmonics/sound/ and wear, while increaseing HP.
Most engine builders will agree aluminum rods are good for these things:
Weight reduction
Harmonic reduction
less teardown due to bearing wear---less harmonics
absorbing impact much better than steel, hence lessening the noise of combustion
Correct,
Ti would have been nice too, but the cost is crazy i was quoted $7500 a set after a 15 set build!! thats a 115K buy in
so i tryed....but Ti would have been sweet.
I should correct myself. When I said the small end was offset, I didnt mean that the step was up there. Not really sure why I even said small end On a buick rod the offset it just above the big end. Although the D-Max does look to be a off-center motor there is just more material on one side of the big end to make the offset. Doesn't look like there is a transistion in the beam itself.

I agree with this statement. But this is because they "flex" a little. It is also common for bearings to last longer with Al rods (as long as the big end remains round) but the rods don't last as long. Not trying to flame about flex....just that its the reason they do the above quoted things.....kind of like the difference between firing a pistol with your elbow locked or with it slightly bent
I was told the rods were interchangeable. You can use an LBZ rod with an LB7 piston and vice-versa. Now I'm more confused.
Pictures of a stock rod for those wondering about offset. the centerline of the rod itself is not offset (Pin to big end), There is a difference on one side of the rod (Crank side). The rod has a chamfer/fillet, and that is the side that is closest to the crank. It is extended out further then the other side, but not making the rod itself offset. The rod bearing still sit's centerline with the pin end.

Wow! Impressive.
Wish I would have thought of that.
Can't wait to see the rest of the build.
Stick around, you may learn something
Although I doubt any of the heavy hitters will learn anything from this thread I think there is a lot of good tech for the average guy. Heck I just learned that our motors are off center.

i remember 2 years ago at merchants spring fling- i talked to you about aluminum rods and you told me it wouldnt work because we have to spin a 80 lb converter. Care to discuss it now? I think that the engine will rev up alot faster and more rpms are to be had.
keep in mind the motor these rods are going in isn't going to have a converter ;-)

Wade say's!
"ill post pics of the progress as it comes together on dmax central, but to answer it's still in the chassis shop getting the ---> linco <--- mounts put in. and a few other goodies. Should be up and race ready some time in may. Engine and all!"

WICKED DIESELS
you need more fuel
dude your graspin, a clutch and flywheel are alot lighter than a TC and much easier to spin.

Yea i wish you did too! Good thing Mike shelton listened....:hug:
