350 timing and carb help

i put a "3/4" cam in an 84 350 in my rs. the cam is a crane energizer 10017. need help setting timing, valves and also wondering if an edelbrock 600 is too small of a carb to run on my engine? thanks for the help everyone

Re: 350 timing and carb help

  1. Remove the valve covers.
  2. Identify the number one cylinder. Turn the engine over until you see the number one cylinder exhaust valve rocker arm JUST START to move from the closed position to open. You may need to turn the motor over a couple of times to reach this point, but do not turn any further.
  3. Locate the intake valve.
  4. Using the thumb and index finger of one hand, grasp the intake push rod below the rocker arm, and rotate it back and forth (clock-wise and counter clock-wise successively to be sure there is no remaining pressure on the push rod from the rocker arm as you loosen the rocker arm adjusting nut.
  5. Using the other hand, while continuously performing step 5, with a 5/8 socket and ratchet, tighten the rocker arm adjustment nut slowly until you feel a resistance of motion on the push rod.
  6. This will be the zero lash adjustment point. For hydraulic lifters, tighten the rocker arm adjustment nut 3/4 of a turn. For solid lifters, back off the rocker arm adjustment nut until your feeler gauge just fits under the contact point between the valve stem and the rocker arm. Fine tune the adjustment by checking it with a feeler gauge just slightly thicker than the preferred clearance to be sure the clearance is not greater than it should be. If the larger feeler gauge will fit, it needs to be re-adjusted. A lash tolerance of 1-2 thousandths of an inch in the valve adjustment for solid lifters would be acceptable since it may be difficult for someone who is in-experienced to be more precise than that.
  7. Turn the engine over until the intake valve opens and then is almost closed.
  8. On the exhaust valve, repeat steps 5 through 8 for the exhaust valve adjustment.
  9. Repeat this procedure for each cylinder. Be sure to do each cylinder sequentially, either following the firing order, following the cylinders numerically, or in the case of a V8 doing one side of the engine at a time. I prefer to do one side of the engine at a time.
that will take care of vavles,to set distributor timing make sure the rotor button is piontiong to #1 spark plug wire on the compression stroke with pointer on balancer pointer is on the right mark, when installing cam did you line up dots on timing gears?

and no 600 edelbrock is not to small i dont care what anyone says, but i run a 600 edel on my 383 with way bigger cam than that... a smaller cfm carb will give better fuel milage, and quicker off the line while still having plenty in upper rpms, where as a bigger cfm gives more high rpm pull, and worse gas milage, (i have a 750 i run when i feel froggy but everyday the 600 is my favorite) its all really in preference im not diss anyone or any carb just giving you my thoughts on the matter, I love my chevys....
