410 LA small block will not rev past 6000

Thank you for all the idea's! I'm going to play with them one by one, and see if something fixes it. I for sure have came to the conclusion I need a bigger and solid roller cam if I want to play in the 6500+ RPM range anyway. The car is such a hoot to drive now not sure I want to do that in fear of loosing low end and possibly the EFI not playing well with the cam. I never meant for it to be a drag car just a fun stick shift street muscle car, and that it is.
