    I'm considering installing a cam in about 2 weeks. I was just going to replace the timing chain, but am considering a cam also now. The truck has over 170,000 on it. What I'm wondering is if I'll have to remove the entire front of the truck, or if I can just pull the radiator and move the a/c cooling system out the way. If I have to remove it, I may reconsider this. Also, would it be possible to remove the header panel and just lay the cooler out of the way?

    If any body has any knowledge in this, please advise. Thanks guys,

    Corey

    Corey,

    I have asked this question on a couple of occasions but haven't had much luck with replys. It appears to me that you can remove the grill, top of the shroud and the radiator and carefully support the trans and oil cooler, and have room to work. I would really like to know what cam you are going to use. I am researching cams, intakes and headers at the present time and plan on doing the work durning spring break. Do you have any good suggestions for headers?
    Edlebrock has an intake, cam combo that looks pretty good and you don't have to modify the chip.

    Do you have the part numbers for the Edelbrock intake and cam?

    Cam - 3702
    Intake - 3704

    The numbers are right, but I did it from mem so I could have reversed them.

    I resently went to the com cams web site they actually have a tech department that you can email with your specs and they will give you a recommendation. This is what they recommended for me with 350 4:88 39" Swampers and a 700r. Part number 12-235-2. This cam has a duration of 254/262 and at .050 of 210/218. The lift of the cam is 447/462 and it has a 110 lobe separation. The rpm range is from 1000 to 5200. My K-5 is 1986 so there may be a different cam for the newer K-5. Hope this helps.

    well there is a way to get a cam in without removing the whole front end,,,
    if you pull out your cam it will more than likely hit the support post on the front end where the rad. is,,,
    you can however "trim" this outta the way with a sawzall !![​IMG]

    I've done this on my '75. It doesn't look like the dimensions have changed much on the newer K5's. I had to remove the radiator and get the a/c condenser out of the way before I could get the cam to come all the way out. [​IMG] Just needed a couple more inches, but the condenser was in the way.
