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.

If you are happy with the way it drives and performs.... leave it alone.

What is the fascination with 6500rpm? It's just a number.

Would you be happier making the same HP and TQ at 500 more rpm than you do now? If so, you'll need more gear and you will just be tougher on your parts, especially valvetrain.
