Before you try another take a good flashlight and have someone turn the engine over to make sure the pushrods are not rubbing on the block or heads. I had some major grinding to do on both my Keith Black block and the 440-1 heads but I am using 1.6 rockers.

Well the heads/ pushrods / rockers and spring package all came from the same place all new !!! PtoV was .110 intake and .140 exhaust ... I'm not blaming Best Machine here one bit so no one twist that! They have contacted Trend and I am sending the whole lot to trend to be analyzed ... I have about 180 miles on my engine I believe it will be on my new odometer I installed. Once and if the pushrod was to blame we will go from there !!! Best Machine has been top notch to me from day one when I first bought all if this...

I would tend to think its a break based o9n some some of meterial issue or during the heat treating process. I believe Trend buys there moly tubing in 21' lengths. ( maybe rolls but I dont think so) Once they determine what lengths they need. the tubing will go thru an annealing process. Thats usually about 1-2" from the finished end of the required tube length. I'd have to guess, they may find a problem in that arena. john is a good guy at Trend, and he will get you an answer for sure. It will be interesting to see what they find.

I have seen Smith Bros. do the same thing, I had one break during a pull on the dyno, it broke the top off of a Crwoer roller lifter and ended up guaging the cam lobe  On eof my freinds had the same thing happen on another set of Smith Bros but it broke at the very top under the ball cup end, mine had a defect in the material where it broke  I now have Mantons in all of my motors, PM if you want a set.

See if you can look thru the spark plug hole with a good bore scope , check the exhaust relief in the piston for a contact mark, You wont always bend a valve with piston to valve contact, We broke a push rod in the middle like that pic of yours, turned out to be a guide that was too tight, I ran this engine for 2 weeks on and off at the shop and it was fine, broke the push rod on the return road after the first pass, I ended up pullin the heads cause I couldn't find the problem, I bought a good bore scope the next day

no bore scope here .... Im just gonna have to wait and see what trend says as they are gonna inspect them over! Its hard to believe a ptov contact (if the valve hung open like you said) wouldnt bend a valve but snap a thick "Trend" .135 wall HD pushrod so clean like that... youd think the valve would bend and pushrod bend before that happened to a "Trend" pushrod... should know something from Trend next week!

Though would not expect such a heavy duty pushrod to break without some type of excessive strain to be induced to it....

got ahold of my buddy a machinist and engine builder and he brought over a bore scope  neither of us could see anything on the piston or the valve! Neat tool to have! laid a straight edge across the retainers etc. and all are straight! just trying to be as fair as possible here... we will see what Trend says and go from there now!

That break looks like its brittle material... and it would tend to break in the middle like it did... I would be waiting for Trends to say something(or call them)

That to me looks like a brittle break - could be the steel was tempered wrong
If the steel was tempered wrong, ALL of the pushrods should be replaced..
We had a similar problem a couple of years back with some Crane ductile rockers..
Defective tempering process.. With the stress the valve train takes not worth the risk..
Just my $0.00..

No word back from Trend yet?  I worked in a specialty steel plant and it never took us that long to test our product. I surely hope Trend is a company we can still trust to make a great product.

Thanks Pete, Good to hear that. Its to bad people want to blame someone else before they make sure everything on there end was ok. Its not like we all haven't messed up a time or two but I guess pride enters the equation. Trend has been a trusted name in the racing world for a long time.

If you roll the 2 pieces on piece of glass or surface plate, do they apprear to be bent?
You may need to dress the burr at the edge of the break.

I'd start looking at the entire valvetrain before making any calls. How close do you run to spring coil bind? I'd throw an adjacent pushrod in the problem ho le and measure lift, watch trajectory during motion. Take a spring compressor (jesel-style) and see what addl. travel you have until C/B via the dial indicator. Get back with us.  If you bought the parts seperately and married them together then, unfortunitly the burden of responsibility lies on you (the end builder).

I still have never seen one snap in the middle like that. I used to run 3/8ths .135 wall manleys and never broke one.
I now have 7/16ths .165 walls and picked up 700 rpm. So my old ones were flexing.

I knew it!!! It was Supercomp's fault all along for not making certain you understood what he told you. I doubt he'll let you throw him under the bus again. I will give big props to Bigtime for being patient and helpful. I doubt this post will change how you operate but, as a business I personally would not do business with you based on how you've been posting during the whole process of your build. IMO you have bashed BEST, and Trend and then backpeddled. Yet the truth is not out. Noone, including you, knows what the real reason of the failure is because you have not taken the correct steps to validate measurements during building. I really hope you take this constructively and we move on because it appears you have built a cool car there. People here have been willing to help with good advise etc. so, you can do it yourself, and save or have some satisfaction.

It took about 5 seconds to blame Trend and 3 weeks to finally admit he screwed up. What's the big deal, we all have and will hopefully live to do it again. Live, learn, and try again. You have a very nice car that runs great.!!! Now go enjoy it.

HardcoreB...... plese re read what I posted all above! Show me one time where I bashed Best Machine? look through all the posts how I said this had nothing to do with Best Machine from the get go! I also talked to pete and also said this had nothing to do with him! Yes I went by what supercomp said but clealry stated "I" missed it regardless and it was MY fault "Yep sure did... I missed that one all my fault"..... you twist it all you want I dont care.. obviously your pro Best Machine by your sig! which shows your attiitude and mis reading of posts.. you "edited" this out of your quote for some reason??? "Yep sure did... I missed that one all my fault and it had nothing to do with the pushrod deal !" Have a nice day!

...(do a search hardcoreb). They sold me the heads... then sold me the T&D rockers. the T&D rockers they sold me would not clear the spring package they put on the heads (yes I posted about this in the past) I sent my heads back and Best Machine made it right! Great company thanks Pete
That's how I remember it happening. Someone help me dig up that old post. At first you were flipping out, all mad at them and even named the shop. Look I'm not here to go back and forth...just want to move along and enjoy or not enjoy your progress. All I'm saying is please think about how people are going to perceive what you post before you submit. And I recognize that every once in a while someone's gonna be offended by what you or I say.
