      LS3 intake options buy new or used?

      I just bought a GM Performance LS3 430HP long block from Summit. Swapping out cam and having Texas Speed do the heads. I知 primarily going to be doing Auto X, road course racing, and hill climbs in a 65 Nova with cowl hood and DSE everything. Looks like a new LS3 intake from GM is back ordered. Seems to be a lot of used ones on Fleabay in the $300-$500 range but they look beat up. Would you guys wait for a new one to come back in stock or go with something like FAST for an intake?
      Thanks for any input.

      I bought mine from a chevelle member with fuel rails for 275.00
      It was new off a crate motor.
      Don't buy used everyone wants as much as a new one frome jegs sells for 500 plus they went up were 314
      Minus the rails and injectors.
      72 chevelle.

      Lots of used ones out there i wouldn't hesitate to buy a used one in good condition or right price, especially if it gets you up and going vs. Waiting on parts. I often find them on Facebook marketplace.

      I would buy used, pull all the electronics off of it, then clean it to the absolute best of your abilities before you run it.

      I bought an LS6 intake for my swap and used a set of engine brushes I had along w/ degreaser and wheel/tire cleaner, intake looked brand new and I didn't have to worry about anything lurking inside the intake when I bolted it on.

      Brushes like these, had picked them up from Summit a LONG time ago, might be able to find something cheaper or use an old bottle brush you have laying around: https://www.amazon.com/Moroso-61820-...7346312&sr=8-2

      LS3 intakes with the "rod mod" flow just as much as the FAST intakes. Maybe check one of those out from a reputable guy. I can't remember the guys name, but he does them on other forums I think.
