LQ4 intake swap for a 4 bolt 90 mm TB

[genXhunter]

Was thinking of using a 90mm (actually 88mm) throttle body off a newer 6.0 & 6.2 truck engine with the 4 bolt pattern but my stock intake is for the 3 bolt throttle body. Does GM make a 4 bolt intake that will work with the regular cathederal port heads on the 5.3L? If I had a 6.0, I'd use the L92 heads and intake swap but don't want to go that route just yet. I've gotten 375+ hp so far out of my 5.3 with a small cam, headers and slight mods but am looking for more. My truck is a 2006 model. Any help in this matter would be appreciated.

my 2007 GMT900 is a four bolt TB cathedral port intake. The LS2 intake also works for a four bolt TB and is cathedral port, 90mm also.

search "TBSS intake"

Has anyone ever done the swap? Is it worth the trouble? I already have the 90mm 4 bolt TB but have nothing to use it on. Where can I find one cheap?

There are many on here with LS2 intakes. I had one on my previous engine, Quik has it, TxSilverado I think has it... many if you search.

The throttle body is the easy part... or having to install the Intake and TB combo... but you need the Dr X adapter harness to make it work......

...this is what the LS2 swap looks like and is exactly the same as doing the LS6
