I'm making this thread to ask questions as i do my LS swap. I have my new engine. LQ9 block out of a 2004 SS Silverado, 55k miles, stock bottom end, 0821 heads, comp cam 273 LSR cam, Ls3 intake, 90mm TB. It was in his truck and i got to hear it and go for a ride….so i know the combo works…there has been questions on the PTV clearance on this set up. He did the build and never did a PTV check, and has 1k miles on this set up with no problems.I now the water pumps need to be changed and was thinking maybe electric?? I'm waiting for Holley to finish their 1st gen LS swap kit (Brent made me aware of the upcoming kit) before i change out the oil pan.
