The L67 rods will not work w/ L36 pistons. I'm 99% sure that is what the dude/dudet that relied meant. So if you buy these rods you'd need L67 pistons too.

but...if they're cast iron are they any better than what we have now?

[mrbako]

because the l67 rod is cast iton...the rods they are talking aobut are l32 rods...please read !!!

The L32 has hot-forged "powdered metal" connecting rods, also the L67 in the 2004 Impala/Monte Carlo may have these too from what iv been reading. There may have to be some machining involved to safely avoid problems if you do not have a stock setup.

pardon my ignorance, but what engine is the L32?


Also, say you had a stock, N/A 3.8 in an fcar, and you wanted to reinforce it a bit in preperationg for putting on a powerdyne supercharger. Do the L32 rods require any modification to fit in our engines as replacements for factory rods, or can you even put them in without a supercharger, and run the engine as normal? Im thinking if i have to rebuild my engine before i have the cash to buy a supercharger, i might be better off with the L32 rods.

They do look better, and the design of the cavity in the middle appears to be better suited to prevent premature failure.

The new L32 is the name for the "Series III 3800"

The old L32 was the 3.4L

I have a set of Intense 9.5:1 pistons which I was going to install pretty soon, so which rods are going to work with my set up. Intense says to use L67 rods with their pistons. Will the L32 rods work with these pistons or do they need to be modified?

[GTPprix]

L32 Rods will work perfectly with intense pistons, in fact I was the first to use the Series III Rods in a series II [img]smile.gif[/img]

[ssms5411]

Thanks for clearing it up for me , now I know what to get. What about main bearings still same as L67's. This is what part # I have 12480819.

Yup, they are the same. I'd use the Clevite 77 line main and rod bearings, those are also available from INTENSE.

This is great info, thanks for posting it. I just tried the link to clubgp, I guess it's down right now.

Do you have any photos or more info on what needs to be clearanced for these rods to work in a Series II motor? I need to start getting my parts list together, don't think my stock bottom end will like this new Procharger unit for very long. :D

No problem just glad to help, let me see if i can dig up the pic for you. The piston end will need to be clearanced ever so slightly on the top radius if using forged pistons, nothing 12 seconds and a grinder cant fix.

Heres a link to the photo:

Are they forged around the piston and crank?? The rest of the Rod looks cast Iron..

[GTPprix]

Whole rod is forged, those areas are the only machined parts. The rod is Hot Forged Powdered metal which has a similar appearance to cast iron.
