Lt1 rods?!

That admin doesn't know what he is talking about. All stock 2.8/3.1/3.4 rods are forged.

Pre-67 SBC rods are the small journal rods.

They are forged powder metal. They are not stamp forged from a inget of steel if. Maybe thats what the admin is trying to say.

[RacerX11]

I don't think so. Do you have some information that shows them to be powdered metal? GM didn't start using powder metal rods until the mid 90's. I have never seen any reference to the 2.8/3.1/3.4 rods being anything other than standard forged.

Yea sorry my bad it looks like they are forged steel. In any case they are obviously very strong and I have never herd of a story where one broke under power. It has always been due to a bad bearing welding itself to the crank and snaping the rod

lol... thanks for verifying that for me. this admin thinks that its teh L36 blocks that only got forged rods while our motors got shitty rods. I've tried convincing him otherwise but its a lost cause. and this is from a guy with a built turboed 660 (the admin that is)...
and thats why i only come here for indepth technical knowledge...

RPMs kill rods. Bad oiling as stated kills rods. Crower has some good rods for small jurnal SBC.
This will require bushed small ends for stock pins or costome pistons with SBC pins.

hmm... well unless their site has been down all day, looks i got anothe ban from that site... lets see if this one lasts longer than the 2 days for the last one... all this cause the moderator wont admit he's wrong and is now just outright lying to people... guess you're not supposed to correct moderators no matter how wrong they are...

no no no no no, he has a 3.8L, that would be a 690

i doubt they banned you, they didnt even ban me

[camaroman1181]

lol.. yeah, my mistake.. for soem reason, i keep thinking he has one of our engines.. and i dunno.. it would be stupid if i got banned for correcting him but i havent been able to log on to the site now for 1.5 days.... that seems odd to me... oh well.. i guess we'll have that...

what kind of rpms will a balanced rotating assembly take?

[sharkey]

balancing an engine doesnt make mean it can rev higher. it however will run way smoother causing less harmonics, and make a better running engine.

[614streets]

There is no such thing as a cast rods . If you know of one let me know all rods are forged.

[geoffinbc]

The 660 uses forged steel rods.
The 3.8L uses powdered metal

If that admin does not believe you or anyone he can take a look here

Make a mental note here kids....ALL RODS ARE FORGED. EVERY SINGLE ROD BUILT FOR A SBC AND 660 ARE FORGED.

Thats all i know for sure but i can assume every other manufacturer uses the same.

I think GM started the PM rods around 98? Anyways just a better way of building a forged rod.

Go aftermarket. Nothing GM made from the factory is better than you have right now. Especially some 30 year old rods from a swap meet. The correct rods from Crower run about 550 USD.
