    Best aftermarket cam for a stock 350 vortec EFI

    I have a 1997 Cheverolet silverado 1500 z71. It is a ext cab (3 door) shortbed. I have the FIPK K@N Intake system as far as anything bolt on and thats it. I am looking to get some more power out of it. I am really wanting to put in a aftermarket cam along with the headers I am getting ready to install. Could anyone give me some ideas about a good cam that will work in this engine. Considering the fact it is a EFI it may mess with some things. Thanks

    Where abouts in Kansas are you? I'm in the KC area, in Overland Park or what some call the Shawnee Mission area.

    Anywho the stock Vortec cam is pretty decent makes great low end torque which is what a truck needs. Maybe try getting the upper and lower intakes and heads ported; i'd say LT1 top end equipment would be a step up but I don't know for sure if it'll bolt up without complications. You're already getting headers, i'd assume you're getting longtubes and adding a mandrel bent true duals with a crosover which will help a lot especially with a built motor. Also try some 4.10 gears if you haven't already, the best performance part you can get for the money, guaranteed to work it's not a gamble like a lot of performance items.

    LT4 or ZZ4. The LT1 cam is a waste of time in a 350 vortec.

    Watch lift closely so you don't go beyond the supposed limit of .480 or so. And I'd swap springs with ANY cam swap. You can buy the LT-4 used in perfect shape for $50 - $75, use the difference between that and an aftermarket cam to buy new springs.
