Once you did this, where was the timing line on the balancer in relation to the timing tab??

No problem- the same procedure is used from the 262 to the 400 SBC, as far as setting the valves on a hydraulic valve train and for wiring the ignition wires and setting the distributor in place correctly.

You first need to find TDC on the compression stroke in order to install the distributor correctly. Sometimes the damper line and timing tab are not correct- like if a different tab or damper was used.

To adjust the valves, I use the EO/IC Method:

In order to adjust the preload, the lifter must be properly located on the base circle or "Heel" of the lobe.

At this position the valve is closed and there is no lift taking place. You will need to watch the movement of the valves to determine which lifter is properly positioned for adjusting.

1. Remove the valve covers, and pick a cylinder that you are going to set the preload on.

2. Hand rotate the engine in its normal direction of rotation and watch the exhaust valve on that particular cylinder. When the exhaust valve begins to open, stop and adjust that cylinder's intake rocker arm. (Why? Because when the exhaust valve is just beginning to open, the intake lifter will be on the base circle of the lobe, the correct position for adjusting the intake.)

3. Back off the intake rocker arm adjuster and remove any tension from the pushrod. Wait a minute or two for that hydraulic lifter to return to a neutral position. The spring inside the lifter will move the pushrod seat up against the retaining lock if you give it time to do so. (If you are installing brand new lifters they will be in the neutral position when they come in the box.)

4. Now spin the intake pushrod with your fingers while tightening down the rocker arm. When you feel a slight resistance to the turning of the pushrod, you are at "Zero Lash". Turn the adjusting nut down one half to one full turn from that point. Lock the adjuster into position. The intake is now adjusted properly.

5. Continue to hand turn the engine, watching that same intake. It will go to full open and then begin to close.When it is almost closed, stop and adjust the exhaust rocker arm on that particular cylinder. (Again, when we see the intake almost closed, we are sure that exhaust lifter is on the base circle of the lobe.) Loosen the exhaust rocker arm and follow the same procedure described before in steps 3 and 4 to adjust this rocker arm.

6. Both valves on this cylinder are now adjusted, and you can move on to your next cylinder and follow the same procedure again.

DETERMINING TDC will allow you to be sure the timing tab and damper are correctly indicating TDC.

MAKE A TIMING TAPE to see what the total timing is, w/o needing to use a dial back timing light. You can also buy a timing tape, they're not very expensive. The problem is if you have a different diameter damper than what the timing tape is made for.

can i spin the engine around and set the timing line on H.B. in the deepest v and be on the compression stroke? also if the valves r too tight could that cause a foot or two of a gas cloud to spit out of the carb?

If the timing tab and balancer line is correctly showing TDC, you will be either right where you want to be, or 180 degrees off. That's why you want to either use a finger on the plug hole to determine the compression stroke, or remove a valve cover (yours are off now?) and watch the valve action to tell when you're on compression.

Having the valves too tight can cause a fiery backfire up through the carb. The timing being off will do the same thing sometimes.

When you go to adjust the valves, back off the adjustment nut until there's play. Then as you tighten the nut down, try jiggling the pushrod up and down instead of twisting it. This will help you to feel/hear when the slack is taken up. Once the slack is gone and you are at "zero lash", tighten the nut an additional 1/2 turn. Then go on to the next valve.

Sorry for interrupting. I didn't realize until now that there was a second page of the thread already in progress! My mistake, I'll sit back and shut up now.

You prolly have the valves adjusted too tight and/or the distributor 180 degrees out.
He said he just popped a cam in it. I'm betting he didn't rotate the engine 360* before he dropped the dist. in after lining up the dot's on the cam
& crank gear.

Keep that up, and your going to be looking for a car to put those engine's in after it burns to the ground. Find out what's wrong.

If you didn't rotate the engine (after lining up the dot's on the cam and crank gears) 360* you need to put the timing mark on TDC, pull the dist., rotate the engine 1 turn till the timing mark comes back to TDC and re-install the dist.
check rotor posistion and start your firing order clockwise starting with the tower the the rotor is pointing at. If you allready did that, look somewhere else and pay no attn. to me!

i got restless and did what u said turned the distributor 180. its tryin very hard but its still not running. i had it running for about 4-5 seconds but thats it. tommorrow ima mess with the distributor and find the right timing for it. hopefully itll fire right off and scream. this engine is very loud so far. 2 1/2 exhaust with 3 inch flowmaster 40s no crossover dual exhaust.
