Or change fuel injection systems. Some guys do what i think is called a 411 pcm swap. You might look into that. If you don’t want to spend the money on a aftermarket FI system. I was going to take the old Holley system out of my stocker. And put it in my bracket car. Then put a newer up to date system in my stocker. But there is no more 1/4 mi bracket racing here anymore. So I just left it as 1/8 mile it’s fine. You could try different PCM’s of the same part number. As some do get a tick more rpm before the quad drivers lock up. But you could spend a lot of money and not find one.

Learned that ODB1 limited to 7000rpm
LT1 ODB2 Limited to 7200 rpm
Trying to find out if the TorqueHead is a legal replacement?
