Checkout our recent dyno results from the PRC LS7 cnc ported heads! They make 30hp over stock castings & sell for bellow new gm heads!!

We've made over 750 flywheel horsepower with those heads on our TSP 454 LSX!

Wow, this has to be the most vague question I've ever seen asked on this forum.

What are your power goals?
What is the car going to be used for?
How much are you prepared to invest?
Are you planning to use power adders?
Do you want fuel injection or carb?
What kind of car is this going in?
Is hood clearance an issue?

Don't look around much, do you?? This kind of question is asked at least 5 times a day. Go to the GEN 3 internal engine and soak up the glory of the hourly "which cam" thread.

You're right, I don't look around much. I'm usually trolling the parts section trying to get stuff for my build. I have to admit though, I've even had a thread out there trying to get help finding a cam to work with my P&P LS7 heads.

People just have to realize there is no perfect answer to vague questions. Give us more info and we'll tell you what we know!

There might not be a perfect answer, but these things have to be damn close
