  • 1986 Volvo 240 camshaft questions

    I am looking into upgrading parts of my 1986 Volvo 240 and have my eyes on IPD's VX sport cam. This is my first car and my first 'build' so I am pretty unfamiliar with most things. I have IPD's high flow exhaust kit in the mail right now, but I want to do the camshaft after to get some extra HP. My only concern is if the car will pass the California smog test. The car just got smogged last week and it went perfectly fine, but my dad has concerns on whether or not the IPD VX street performance cam (https://www.ipdusa.com/products/8771...230-ipd-115454) will pass. I read on another forum that the K cam was seen to be the one that had the best shot at passing in CA, although when I search for K cams, the VX cams pop up. Are these the same? As I said, I am pretty clueless so far, so these questions might be very silly. But this is how I will learn! Any answers/advice would be very helpful!

    the K cam has a higher lift and more duration than the VX cam, I would think the VX cam would pass a emissions test easier than a K cam.

      This helps a lot, thank you. The VX cam looks like it will be better for me. Regarding the lift, do you think I will need new valve springs or do you think I will be fine? I obviously don't wanna damage any parts, but I see that most people are usually fine without new ones.

    springs will be ok but I'd check for the proper clearance, you may need to replace some shims.

      You will DEFINITELY be changing valve shims
