5.3l help
Oiling is one of the big weaknesses of these cars. I can't remember the name but there is an aftermarket windage tray I have seen on here that is supposedly way better than stock. Oil cooler will also help for sustained rpms.
If $$$ no object a dry sump system is for SURE the way to go (several grand IIRC).
Take it FWIW but the road race guys now run LS6 blocks instead of LS1's cause they don't have the oil starvation probs that the LS1 did probably due the windows cast in the block to enhance better bay to bay breathing. I am just trying to help but don't take this as gospel.
BTW I love it!!! A LS1 in a 240 will be a NASTY BEAST no matter what you do with it
