L88 cam in L78?

[Born30YrsLate]

I'm still trying to figure out all this camshaft stuff...the question I have at this point is that the powerband for the 396/375 cam is 4000 rpm (2500-6500) but the powerband on the L88 cam is 2600 rpm (4400-7000)...what makes the powerband so short in the L88 cam?

Also - the next motor that I build is going to be an L88...I will be using the 074 heads and 198 intake as well as all the other correct parts for this motor, now after reading about the L88 cam I'm thinking that I don't want to use factory cam!.....What is a good cam that I can use instead of the factory L88 cam for a good powerband up to 7000 rpm?....this car will be driven on the street mostly and that won't be very often and maybe a couple passes at the track. This motor is coming with the car I'm buying which is why I'm building this L88 and I'm looking to get at least 525 peak hp between 6500 and 7000 rpm out of it.
As a side note the motor will be backed up by an M22 and 4.56 posi and will have either 255/60R15 or 275/60R15 rear tires if that helps any?...... As always everyone's input is greatly appreciated...... [img]/ubbthreads/images/graemlins/beers.gif[/img]
