I have a pre-LP Gallardo and I’m interested in swapping out the stock sinter metal rods with forged H-profile rods. I see that there are two different versions of pre-LP rods.

07L105401B until 4LA01476 and 07L105401D from 4LA01477.

Are there any dimension differences between the two versions?

And do you guys who have done a pre-LP rod swap have any tips and tricks for me? 😊

There is no dimensional differences in the rods in the 5.0 engine that I have ever seen or heard of so not sure what the alternate OE numbers reflect..

What brand or who is supplying the replacement rods?

The cranks are very weak and no doubt it will not be straight when you remove it.. I check them between dead centres and straighten them as easily as hitting them with a large copper hammer, they do not take much to move them

You will need to balance the crank at a minimum

Have built a lot of these engines over the years

Thanks for the information. The crankshaft thing is a little scary. How do you handle the crankshaft when you measure it? Do you have a jig or do you place it in a lathe?

My plan is to buy the the connection rods from a local expert here in Sweden. Auto Verdi is the small company called. He has been making connection rods since 1988, including some Gallardos.

Another thing. Can the exhaust manifold remain on the cylinder heads, when removing the cylinder heads?

Ahhh nice, Auto Verdi definitely has a good name with their products..

I always had Crower make the rods for us, and ran these Titanium ones in the race engines.. Pictured far right.. How nice is the 3 sinter metal rods on the left.. lol.. 4th one along is a Crower maxilite steel

The Ti rods saved us 1kg over the stock sinter metal, and reducing weight on these bottom ends is handy

Yeah I mostly leave the manifolds on the heads when removing them from the engine block..

Wow, the three rods on the left have had a tough life 😆
Titanium rods are engine porn 😄
I’m happy to hear that you have heard of Auto Verdi all the way in the other side of the world 😊

Can you leave the cam phasers on the camshaft when removing the cylinder heads?
