LTX and LSXPutting LT1s, LS1s, and their variants into Third Gens is becoming more popular. This board is for those who are doing and have done the swaps so they can discuss all of their technical aspects including repairs, swap info, and performance upgrades.
Make your own if you can. I had some 4" spectre aluminum tubing tig welded together with their MAF sensor welded in. You can get all kinds of bends. If you don't want to be that fancy you can buy rubber elbows from various places online, stick a tube in (Spectre makes one with the MAP mount welded in) and add a filter of your choice.

the MAP is mounted anywhere on the actual intake manifold.
The MAF needs to be in the intake pipe.
IF you have a radical cam, and are SD tuned, wire in an LS1 AIT and put that into the intake tube, or behind the throttle body in the intake manifold.
Was checking setups like this while scrolling through https://casinosanalyzer.com/free-slo.../Sweet-Bonanza earlier today. Cold air intakes make a noticeable difference if tuned right. Just make sure to log temps before and after for comparison. Helps to know if you’re actually gaining efficiency.

Not yet I am going to put the Radiator and fans in first and then take some measurements but I think that I will be going with Spectreperformance I called them and they are great to talk with

I keep a few cheapo silverado intakes in stock like this. Use it like a parts kit, not a direct fit part. Throw the filters away as they're huge and terrible. Buy generic K&N 4" for $30
Cut the mounting tabs off and polish the areas after. Mix/match couplers. Buy better worm clamps from lowes (dryer vents), they're much tougher than the chinesium ones
Can make some really nice intakes from those kits for not much money
