Does grinding down ls6 intake ribs make it weak enough to crack? Hey guys,
This weekend I ground down the ribs on my ls6 intake to fit the stock ls1.
I was just wondering if anyone has seen an intake crack or break because of this?

Since the ls6 intake swap was the first mod I did, I guess at the time I didn't feel comfortable grinding down the tabs.
Now, I'd have no problem doing it, but I'm glad I bought the ls6 coolant crossover tube/plugs, as they're considered a superior design.
You'll be fine either way.

Much easier/quicker and can be neat too to just take a wood chisel and a small hammer and just lightly whack it on an angle where you want the ribs to disappear, nothing to it.

The ribs are casting ribs. They are there to keep the intake from shifting during the manufacturing process and are what was used to align the intake when they mated the top to the bottom. Just like the casting tabs on your block, they serve no purpose to the finish peice.

Ohh now I see, so I could still use my ground down intake if I ever go FI right?
also does anyone know if that bottom plate of the intake serves a purpose? I kind of nicked it with the grinder in a few spots, not bad at all but took maybe
.020 of material off by accident.

personally, id rather grind the ribs down or make my own coolant lines out of AN fittings and some braided line.
