i assume that was a later ls2 intake manifold with rec ports compared to the cathedral port 243 heads. i also assume you know this by now, but i figured id throw a comment out there anyway.
Its actully an ls6 intake I could not believe it either but they have the rec ports as well, you can tell its gen 3 intake because the one sensor is on the back of the intake not the front plus google lll XD. learned a lot since this old video lol 😅
@@vincesettineri well, i just did the checking because i was very confused myself, apparently i forgot the car manifolds do have a square shaped port although still a cathedral port design, unlike the truck manifold, which is shaped exactly like the head's ports, and uses the cathedral gaskets.
