Wont aftermarket rods not influence the lubrication of the cylinder walls? Original GM rods had oil thrower tabs on the outer side (crank side of the bearing pocket) most aftermarket rods have nothing? Will I need to modify the rods with oil channels or the crank before use?
I give the video a 9 out of 10. Well done. You did miss out on the discussion of billet rods and what hp or application one should consider switching to them.
Hrmms. I found you cant even get i-beam rods unless for a heavily built 6g72. For a 6g72 if your trying to go high rpm n a build your best bet is h-beam rods. Also H-beam rods even though they are made from steel still weigh less than OEM forged rods because they use better steel like 4340. So you can use less material and still have a stronger rod. Just not as light as aluminum.
Very good summary, other than the billet steel Vs machined from forging. More detail would have been nice, but that's something any builder should be able to build [sorry] on what you've primed them with.
I have yet to see an aluminum con rod that has stretched!!! After miles of abuse and if this myth was true then why don't pistons stretch??? There made from aluminum to and are under the most harsh conditions in the engine
The aluminum rods in my bbc blown alcohol will get about .002-.004 longer after a few hard seasons and twist also a little , plus on a street engine they are susceptible too early fatigue stress cracking from the heat expansion and contraction plus with the normal Engine physics . they get replaced before one breaks usually ,
Alloy rods are drag race only. They stretch, bend and break. And have a very short service life. And in fuel applications are used as a shock absorber as they absorb far more shock than steel.
@@unclesquirrel6951 … Your observations based upon the data collected from your real world blown application are typically right on the money. But alloy rods with more extreme dimensional changes can surely be blamed on the squirrels 🐿
@@pizzandoughnutspage7817 only thing that changes is the heat differences. Aluminum expands when hot that is the only reason they might do that. Why don't pistons stretch????. Also you should never beat on a cold engine with aluminum rods or you will spin a big end bearing and that is the reason they have a pin to hold the bearing in place till the engine and oil are up to temp... not because they stretch.
Yes the rod bolts are actually the ones that fell on the exhaust intake stroke.
This was very well done. Most people don't indicate that rod/stroke ratios work hand in hand with cylinder head flow values and cam timing events.

Thank you for watching!
Excellent!
You forgot to inform us of the difference between pressed in and free float rods
Which one should l used in a 496. Thanks
Dave!
Dave’s not here! 😂😂😂🤣🤣

Now to find aftermarket rods for a Toyota 3ZRFE. 🤔

Thank you for watching! We appreciate your feedback.
What's the deal with the rod bolts going in from the wrong side?
IF you refer to the threads in the cap style it is usually to clear the pan rails and bottom of the cylinders.
Special designed rod for stroker applications. Used to help with pan rail clearance in high stroke applications.
VW & Subaru engines have rod bolts on the other side.
Personally I blame squirrels
Squaids, they're some real s**t.

If you check out companies that manufacture aluminum rods you’ll notice their made slightly shorter because they do stretch!

H-beam rods are really cheap I don't know what this guy's talking about he's never looked in his own catalog I guess
its cheap for the american engines , but for Japanese and german engines it's a bit expensive
