LS3 Intake on Cath Port Heads With Adapters! The LS3 intake is arguably the best factory GM intake ever made, but does it work with cath-rec port adapters used for LSA blower installs? Anyone else ever tried or tested this? The answer is it will bolt on, but the LS3 intake with adapters makes less power (by 18 hp) than just running a TBSS or Dorman LS2. I wanted this to work so bad back in 2018 when I tested it, but it just didn’t pan out. Get a cath port intake! Make sure to check out the sales

83 reactions | Another corvette back for some boost. This time in the form of a LS3 C6 corvette. We did the cam package on this car a few years back as well and now it’s sporting an AA corvette supercharger kit along with some fueling mods to support e85 all done in house and pushed the car over that 700whp mark! #totalautoperformancellc #sslsxtuning | SS LSX Tuning and Performance | Facebook
