Freshly rebuilt 350 not starting!

Did you put the shortblock together, too?

I did. I got it machined and put everything back together myself.

Maybe time to call a guy. Sometimes a guy needs to know when hes over his head. Itll probably be cheaper in the long run too.

Yup. I was thinking the same thing. My mom was gonna take it to a classic car shop

So did you prime the oil system before you adjusted the valve lash? with new lifters they are probably not full of oil so as you cranked the engine and it got oil pressure the lifters pumped up with oil and cause the valvetrain to bind and bend the pushrods.

This might be my problem. How do I prime the oil system?

Pretty self-explanatory, you need a tool to manually engage the pump with a drill. Spin the pump for a few minutes before running the engine to get everything oiled up properly. If you didn't do this, it's no wonder things aren't going well, ouch.

You need something like this.

Could I just use an old distributor or a flat head screw driver for this? And how do I know when it's fully primed?

Not really. I mean I guess you could in an end of the world type situation, but you'll be sitting there cranking it by hand for literally a week. You'll see it coming up under the rocker arms when everything's primed.

So I'll break down my method for you. Sucks but gonna have to pull the distributor, disable the fuel and spark, also pull a valve cover off. MAKE sure the rockers are not over tightened so the lifters have room to pump up. Then use a tool like df2x4 posted it goes down into the dist. hole and spins the oil pump. Watch for oil to come out the top of the push rods then turn the engine over 90degrees at a time from the crank pulley bolt. Now set the lash. Re enable the spark and put the dist back in. I'd crank it like that till oil pressure shows on the gauge and then hook up the fuel.
If your willing to gamble a bit with your new engine (I do this on used engines and crate rebuild motors) you could just leave the rockers loose and crank the motor over with no fuel and spark till you get good oil pressure. Then set lash. My biggest thing is to make sure your not putting fuel in the engine unless your trying to get it to run you could wash out the cylinders and dilute the oil with gas which isn't a good lubricant for a fresh motor. With a new engine and your issues I might be tempted to leave lash a bit loose and once the truck runs for a 5-20 minutes to break in the cam set lash right. It will make some noise but loose lash wont bend push rods.

Looks like I took to long typing.

Thanks so much! I will do this. Any way to tell if I already have gas in my oil?
