ok. i have a problem. wanting to fire motor today, went to set the valves, got all done, and you could take every single rocker arm off of the pushrod they were so loose. any answers for this??? went by the chart in the speedway motors catalog, which i have done before with no problem. i also checked to make sure i started on the right stroke and that was correct. i ran a 355 last year and switched to a 383 this year and am using the same pushrods. do they need to be longer??? PLEASE HELP ASAP.

Shouldn't need to go longer. Sounds like your cam timing is off or you just started on the wrong stroke. Reset them. It should be good to go.

Check your timing gear and make sure it is lined up right I had this happen once.

I tried one of those charts years ago and it was too much trouble. On mine I put a button under the hood so I could bump the motor over. Just go one cylinder at a time. When the exhaust is just starting to open, set the intake. When the intake is almost closed set the exhaust. Takes longer to pull the valve covers than it does to check the calves.

He's checking his valves not his calves. Look in the back of a chilton book for something with a sbc. You line up your balancer with your timing mark set half the valves then rotate it once and set the others. I can't think of the order off the top of my head.

you can do it that way but the best and most foolproof way is the EOIC method, when the exhaust opens do the intake, whent the intake just closes do the exhaust. Do it 1 cylinder at at time. This ensures that you have the lifter completely on the base cirlce of the cam. The other way may work for stock cams but with long durations, different ramp profiles etc, you may not be guaranteed to have the lifter on the back side of the lobe.

I went for a long time thinking when the timing marks are lined up, I was at TDC on #1. After having to pull the distributor out and turn it 180, I figured out that when the timing marks are lined up, I'm at TDC on #6. DOH!

Yup got her painted this week so all I have to do is build the motor and and letter it and couple little odds and ends. How you coming on yours just email me so we don't fill up his thread.
