If I was going to pull the cam anyway, I would certainly upgrade it a bit. The Slant 6 is so down on power to start with especially with a heavier truck. Oregon cams is your friend.

Does anyone know the best stock cam for low end torqueand fuel economy. I have found the engines i have had the hydraulic cam ones tended to be best but it may have been due to ither variables like wear and things. Or if anyone knows where i can find specs in the few diferent stock cams. Thanks |

Most of the factory SL6 cams were pretty mild... Do you plan to stay with the hydraulic lifters or change over to a solid lifter set-up? DD |

I have a few vehicles with the slant six and just noticed the hydraulic seemed to have the best low rpm torque. I am planning on putting a low miles 1968 225 into a nother truck of mine and while its out wondering which cam.will.give the best low rpm torque so likely the smallest one but im not sure i will replace valve seals and check it over before i put it in anyway. The truck will be just a daily use truck foe driving to and from work has 3.55 gears and np 435 trans is a 4x4 1979 |

If you are just swapping parts for a better combination, pull the 1968 camshaft from your swapper engine, and steal one from a 1972-1980 225 slant six... it is very slightly better... while doing this you will be money ahead anyway to install a new timing set and degree the cam while regasketting the engine... |

Ok thanks i actualy have many new old stock cams from a dealer that moved and noticed that the cams were different. Would you also advance cam or install at factory spec. The truck will likely never rev over 2500 rpm ever. |

I would set it at 4 degrees advanced since it's a truck that should give you a little more low end torque and not limit the rpm too badly (it's still going to run out about 4000 rpm anyway...). |
