On an LSX fooling with your intake can be an HP adder on the LT1 it's basically just there. It's not restrictive and doesn't add or restrict power to the engine so fooling with it is really pointless unless your increasing the TB size and ports for bigger heads. Like others said it's better to play with it only to match it to your big heads. It's kind of the reason the LT1 is a yesteryear motor. It doesn't breathe like an LSX does. If we're talking engine only...The LT1 responds to Head porting, big bores, and big cams that's where you want to put your money in.
I have a HIGHLY modded lt1 Intake that will work with lt4 heads (welded material above roof of runner) plus many other things if you or anyone is interested!! I'd sell cheap, just collecting dust in my shop

Do you still have this intake? Hey bro I’m trying to pm you but for some reason it won’t allow me to. Do you still have this intake?
