I'm going to install some 1.6 RR on my 70 Chevelle 350. I know how to install them, but I don't know the fire order in adjustment. Is there a help out site that anyone knows that I can look up.

Thanks Vinny

You dont have to adjust them by firing order, if you dont want to. Just go cylinder by cylinder,cranking th motor by hand or bump switch, and use the EOIC method (when exhaust valve is opening, adjust the intake, and when intake valve is closing, adjust the exhaust).Hope this hepled a little.

I said that wrong. I didn't mean the firing order, but as in valve adjustment order when at TDC. You can adjust these valves (8 of them) then at another turn of the crank (360 which is the other 8) you can adjust the final set of valves. It's hard to see the valves open and close when i'm laying on the ground turning the crank by hand. Since i'm doing it this way.

I copied this off a Corvette forum, guess it'd work for hyd. or solids.
"Turn the engine over until you can see the timing mark on the harmonic balancer. Using a piece of chalk or other visible marker, place three more timing marks on the balancer: one mark every 90 degrees around the balancer (one exactly opposite the factory mark, and two in between these marks: just get it pretty darned eye-ball close, it doesn’t have to be exact.)
· Remove the valve covers. You may have to remove some accessory brackets in order to do this.
· Rotate the engine over (either by “bumping” the starter or by inserting a socket and breaker bar onto the harmonic balancer bolt) until the factory timing mark lines up with “0.” Observe the pushrod for the exhaust valve on the #1 cylinder: if the pushrod moves as you come up on Top Dead Center, you’re on the exhaust stroke, and you need to rotate the crank one more time. If neither pushrod moves as you come up on the timing mark, you’re on the compression stroke and ready to go.
· Loosen the adjustment nuts on both the rocker arms for cylinder #1 using a deep socket and a ˝” drive ratchet. One at a time, adjust them as follows:
· Place the pushrod between you thumb and forefinger of your left hand (or right hand if you’re left handed…). Rotate, or “twirl,” the pushrod back and forth between your fingers and notice how lightly and easily it spins. As you do this, slowly tighten the rocker arm nut. The instant you feel the “twirl” friction change between your fingers, you are at “0” lash. STOP. Now, notice the position of your ratchet handle. Tighten the nut exactly ˝ turn from your current position. Do the same to the other rocker arm for #1 (when doing this, make sure that the friction you feel as you swirl the pushrod is not caused by your ratchet and socket pushing or binding on the rocker arm – keep things straight and aligned, and watch for false indications caused by your tools). That’s it for #1.
· Now, here’s the trick:
What’s the firing order for a GM V8?
1-8-4-3-6-5-7-2
How often does a cylinder fire in a V8?
Every 90 degrees
That means we can now rotate the crankshaft 90 degrees at a time, and go right to the next cylinder in the firing order for the valve adjustment, with confidence that both of the valves for that cylinder will be closed and ready to adjust.. So rotate to your next chalk line, and adjust #8 as described above. Rotate to the next line and adjust #4. After you’ve rotated the crankshaft twice over (using the starter and “bumping” is the easiest way), you’ve finished your valve adjustment! No oily mess, no worrying about if you missed a valve."

Rusty Bucket that's what i'm looking for. Thanks for the rotation of adjustment.
