Cathedral Port LS intake
« on: January 12, 2021, 12:51:52 PM »
Working on swapping a 5.3 into another FB, has anyone purchased an LS1 style intake lately??  Seems like its a minimum of $300 to $400 now, Dorman doesn't make one anymore it seems either.

Rock Auto still has Dorman LS1 intakes listed for $325. I'm not sure how the Dorman LS1s compare to OEM, but an OEM LS6 intake is a good upgrade over OEM LS1. Looking on eBay, the prices for LS6 intakes have definitely gone up. I think I paid around $350 for mine 4 years ago. If the car is NA, try to get as complete of an intake as you can. Having to buy a fuel rail, regulator, injectors adds up quick. And FWIW, you can use DBC truck throttle bodies with the LS1/6 intakes to save some money.

That is the plan, can I not use the truck injectors though?  I thought you could.  there is also only 1 intake left, probably gonna have to snag it.

I think that'd depend on what style injectors your donor truck had. I think there are 2 or 3 different injector lengths used on the LS platform.

I almost pulled the trigger on the Dorman when the prices started climbing, I found one for like $400 on car-part or something. Really regret not doing it now... JEGS still has a couple at $780 or so.

At that price though, I'll just grab a used FAST 92 off lstech or something.
