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

If you took .010 off the heads and .030 off of the block you would have needed shorter push rods or shim your rocker shafts. Did you do so?

It had the steel shim head gasket from the factory and I put a composite head gasket on so the should have taken up .020 of the .040 that was cut from the block at least that's what I thought. I hope I was wrong and the problem is just push rods too long.... and maybe a ruined cam.

When I take this car for it's first drive I think I'll bring a priest with me and drive it to my enemies house park it in his driveway then have the priest do an exorcism on the car so all the evil and demons go to my enemies cars ...... hahhahahahha

Or maybe have your enemy take it for the first drive

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?

---

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.

Ok I got my push rod length checker made and these are the numbers I came up with :

Stock rod = 9.292

Rod checker results from lifter cup to rocker cup :

intake = 9.203
exhaust = 9.210

Is this enough to cause all of my intake push rods to bend. It doesn't look like a whole lot to me.

The push rods are solid not hollow and the valves were cleaned and inspected when the new springs and locks were put on. The fuel system was clean and new fuel before fire up.

If I am reading this right all you did was change the springs and retainers ? if so your problem is the retainers probably hitting the tops of valve guides because that cam has a lot of lift , pull a spring and low at the stem seals , they should show evidence of being crushed between the retainer and the top of the guide .

Also a hollow pushrod is stronger than a solid one .

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.

---

I have to say, if it ran ok for 20 minutes then bent the push rods on the next start up with nothing else changing other than a fuel issue, I would have to agree with this, unless it started running bad during the first start up but after the 20 minute break-in period. It's a little hard to tell, he has 3 threads going regarding this issue.

I would imagine if it hydro-locked it may have bent a rod or two also.

gas isn't like water, if it sat over night the gas would be gone..he'd have to have a TON of gas flowing to do that wouldn't you think?

---

I didn't know it sat overnight before the next start up. It's a little hard to follow the exact sequence of events.

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.

Quick, take off the remote start and hide it so even you can't find it.

I hate to make this sound like a broken record but you obviously have a clearance problem.

1. thats a lot of lift for stock length valve guides and stock pistons and not checking anything. Did you degree the cam? If it is advanced it will reduce Intake V-P clearance. The narrow lobe seperation angle will also reduce V-P clearance. http://www.compcams.com/technical/FAQ/LSAproperties.asp

2. a cam that big probably should not be using stock rockers, pushrods and springs no matter what Hughes may have told you.

3. since you have pistons with notches it might be difficult to see collision damage. If you are looking through the spark plug hole you are looking right at the wrong notches. The ones that might have damage will be facing away from plug hole.

I think you will be pulling the heads and maybe the pistons.
