7000rpm camshaft?
7000rpm camshaft? What kind of specs should i be looking for if I want to rev around 7000ish with my LSX 427 build. Or should I not even rev that high, I have heard the L92 intake quits flowing around 6200ish. What do you guys think?
If you could be more specific about your whole setup that would help make recommendations more accurate. Vehicle type, weight, trans type, rear gear ratio, header size/exhaust system, intake system would be a good starting point. Driving style will also be helpful.
To help get a 427ci engine rev to over 7000 you should consider running the LS7 heads instead of the L92s due to the improved rpm capability of the LS7 intake manifold.
Good luck with your build.

LS7 Carb Style or Composite?
I've seen both setups make power over 7000rpms on 427ci engines. Also I've flowed both style intakes and they both have similar flow capacity. I guess that leaves the runner lengths to determine the actual power peaks.

now what skews this is when you enlarge the port diameter of the runner and increase its volume...... I bet that offsets things just a hair huh?
I'm trying to get the truck down to like 4100lbs. I got 4:10 gears with a M12 T56 and 265/75/16 tires. The engine is a 4.125 bore and 4" stroke. Running 11.5 compression and looking for 1 7/8 long tubes. I like the idea of the LS7 heads and intake, but I can't justify the huge price difference between those and the L92's. I will probably put 150 miles on per week.
