Boost is pretty much air stuck in the intake because the engine can't take it all in .... I deserve a pulitzer prize for that fine piece of literature I wrote there lol

10 psi on a 100mm 427 motor is not the same as 10 psi on a 76mm 5.3......

I'm about to swap a LH6 5.3 over to my TA. I plan on using some 241 heads, LS9 Head gaskets, and my old blower cam. My P1SC will still feed it with about 8 psi. We will see how much it makes? I probably won't start in on this until mid August though.

Cool! Mine is 225/235 600+ lift I wouldn't mind having something smaller yet . The extra valve train noise is annoying
