Liquid fuel running down into the cylinders due to stuck floats can cause hydraulic lock and bend the the push rods if enough liquid was in the cylinders. I have also seen bent rods from this type of engine flooding also. that is why i never start a new motor with a used carb unless it was running the day before on my own stuff.

Ok I just looked down one of the cylinders with a bent push rod. I can't see any evidence that a valve hit a piston. The pistons have 4 valve reliefs in them so maybe I got lucky. Do any of the chain parts stores carry a length checking push rod ? or does anybody have a picture of a home made one ? I have plenty of push rod parts to make one out of ... hahhahahah




if you have a hollow pushrod you can make a checker , just cut an inch or so out of the pushrod and tap the inside for 1/4-28 and get 2 nuts and a length of 1/4-28 threaded rod .

Did it start and run ? Did it die right after starting , seconds, minutes ???

He finally posted that it ran 20 minutes. That changes things a bit...

I was under the initial impression it only ran for a few seconds.

Wow !!! I'm sorry I didn't realize that I did that.... Yes it did run for about 20 minutes then it started sounding like it had a fouled plug and it started again the next day after I replaced the plugs but still ran like crap. Here's link to the post that lead up to me finding out that the push rods were bent.

You said stock rockers and shafts. stock rocker ratio is 1.5 if you are lucky, most are less. Also this means you couldn't have adjusted the valves wrong because no adjusters on the stock rockers.
Your valve lift is just a hair over 0.500 inch. Your springs are good to 0.600 lift IF (and only if) they are set up for installed height of 1.800". But that info comes off the spring box. Was the installed height measured?
I seem to remember stock bigblock heads having a shorter installed height than that.
I keep coming back to either coil bind or retainer running into the valve guide/stem seal. Your seeing no indication of collisions on the piston tops, and the fact that you haven't told us all the intake valves are leaking because they're bent, leads me to think it wasn't valve/piston interference. So what else could it be? Best answer lies on top of your heads.

I'm making a push rod length checker now. I'm hoping that my pushrods were just too long and caused the problem.

when it was runnig for 20 minutes was it a clicky clackety mess? did it run ok? if they were too long you probably wiped the cam. Have you drained the oil yet? Drain it and toss a magnet in it, then pull it out. Or if you have a magnetic drain plug..well you'll know when you pull it out and it looks like Beaker from the Muppets.

It seems to me if the push rods were too long, it wouldn't have run good for 20 minutes. I would think it would go south within seconds...

It was a little noisy but not real bad .... it was after break in and after it started sounding like it fouled a plug that #1 started clattering which made me go look at oil pressure but it was ok. The clatter from #1 made me think that it was #1 that had the fouled plug.

What I was thinking, intake stem to guide clearance but not sure how they got the intakes too tight & not the ex (which run hotter). keep us abreast. Been thinking of a borescope, do they show a clear shot? NO P/V touching right? Just before I hit the OK submit button it hit me that I bet there was a collision

Yea I had a clear shot of the piston and there is definitely no damage on the piston at all. I didn't get to take a picture before my neighbors 10 year old son grabbed the remote start and pushed the button chopping my camera of in the cylinder. I'm in the process of trying to get my camera out of the cylinder with my old borescope. so I've been looking at this piston for the last hour or 2 and it has no damage on it . Man I should have taken up gardening. Hhahahah

Holy crap! Are you freaking kidding me??!! Lucky your fingers / arms weren't near anything. Man, this is just a bad time, you can't make this stuff up!. Good example why disconnecting the battery is a good idea. But cripes, you shouldn't have to worry about that type of hazard.

it's not your pushrods. I'd almost guarantee it.

if the pushrods were too long, then you'd have lifters bottomed out and hanging valves open.

who's valve springs are they? Hughes recommends their own springs/retainers to run with their cams, especially with the whiplash cams.

put a good pushrod into the valve train, and slowly crank the engine over by hand, again and again, let us know what you find. does it crank over smoohtly the whole way? do you feel anything binding up? can you visually inspect the valvespring/valves to ensure the coils are not binding up or the retainer hitting the valve guide?

That's how this whole project has gone so it was no real surprise to me. I'm telling you this car is possessed. 2 weeks ago I jacked up the front of the car to purge the air out of the motor. I was going to the back of the car to put gas in it getting ready to start it for the first time and it fell off the jack. It took out the billet aluminum crank pulley, Radiator, aluminum fan shroud, electric fan and the tranny cooler lines. I have never had a car even come close to falling off of a jack before this car. Just about everything on this car has had to be done twice. Things I've done dozens of times on other cars have to be done twice on this car. I was thinking of putting a cross in it but I'm afraid it will burn my house down ..... Hhahahhahhaha

I bought the whole Hughes setup.... Cam, lifters, springs and retainers. They told me that my springs would be fine because they only had 50,000 miles on them but I bought them anyway. I had them installed by a machine shop that has been doing work for me for years with no problems.

I think I will leave the camera in the cylinder and get the push rods checked and measured because it sounds like the heads are coming back off anyway.
