Ls intake lq9 6.0 - The 1947 - Present Chevrolet & GMC Truck Message Board Network

There are more than 2 intake types, but your correct that there are only two port Styles. Rectangle port and Cathedral port.

What about it isn't fitting? Are the runners not lining up, or something else?

The coolant (steam lines), were not hitting on the bottom of the intake? Longhorn

Don't forget about the LS7, which is also unique.

Ya but doesn't the LS7 use a rectangle port also? You can put the LS7 intake onto an LS3. The runner design is made for higher cube cars, but I don't know if I'd say its another port type. It'll interchange, just not necessarily make the best power on a sub-400ci engine

The ls7 will not fit the ls3. Different port locations.

Yes, it does use a "rectangle" port, but LS7 heads are completely different than LS3 heads...larger intake and exhaust ports, different valve angle, larger valves, and as homemade87 pointed out, the port and intake manifold bolt spacing are different.

No sir. The shape of the port is quite different.

Left to right:

CATHEDRAL
RECTANGULAR
LS7
