What are the limits

[ForcedFirebird]

there are ways to improve the 3400 lifters, i'm actually working on a how-to video for this right now.

Where is it? Spill the beans, cause it will probably work on hyd flat tappets as well.

I'm having issues editing the video, it might work on flat tappets as well... not sure.

So can you buy solid lifters for the 60degree family somewhere or are they the same as in some other gm family of engines that you can borrow from? Also, has anyone seen any performance drop off in power at higher rpms that can be traced to the lifters and how did they know it was from that?

This is planned to be a multi-year project. I am trying to sell my car to start on the build first is getting the LX9 in the car and running. Then Turbo and get a base tune. Finally upgrade all of the parts put in custom rods & pistons, with custom ECU and 20psi here we come.
