So you believe that the cam is so much out of phase that it bottomed the exhaust vales on the pistons which in turn bent the push rods?
I would be pretty ticked at the cam manufacturer or timing gear manufacturer depending on which one is out of wack. I have not ever had this type of problem with my engine buildups...especially with a street oriented type of camshaft...usually they are plug and play.

Yikes, not good. Wrong parts or out of sync? Were the valves hitting the pistons to cause the rods to bend?

Your short duration roller cam should make lots of compression. I was going to suggest you put your finger over the spark plug hole! lol Does it have adjustable rocker arms? You could check the preload on the lifters. If the pushrods are too long it would open the valves all the time would it not? Especially if you are using non adjustable rocker arms.
I recall normal lifter preload is around .030" give or take .010". I had to figure out my pushrod length after I assembled my engine because of some retrofits . More on that later if you need to learn how.
Need to know if it is making proper compression.

Take a deep breath and relax for a will help you think about the problems. Maybe take the time to reorganize your tools. Is it possible your distributor is set wrong? Did you use adjustable rocker shaft arms for this build? You mention that you think you may have used the wrong pushrod length...shorter ones required with the roller cam? If it makes correct compression that will narrow your trouble shoot list down a lot.

It sure looks a lot different than when it rolled off of the line Steve! A video is always cool when you first fire them up. I will be interested in hearing it run...especially interested in how your cam choice will work. Did your last engine run a roller cam? If not you are going to love the difference! She should snap pretty good off the line with your combination.

Good luck! Hope you don't need the bomb squad!

My dad had a 74 Fury III that he special ordered with a BB and low rear gears for towing. Heand my mom picked it up at the Windsor plant as it came off of the line. Anyway, I recall racing some "fast" cars with it in highschool and it ate up many of them in the 1/4 mile. You should have heard the lame excuses my buddys came up with when they lost to the big family car! Big block B Body+low gears=traction+good acceleration. I miss that car!
Good luck with your new toy! Let us know if you take any hot rods down! lol

Cool. I was just a little bit ticked at the time but now I realize after reading more posts here that you were trying to be funny. No problem. I do not come here to argue or cause trouble...just to share and learn.

Some of those pics are priceless! Red neck engineering at it's best! Red Green would be proud! :thumbsup:

What kind of intake manifold it that? I bet you can't wait to fire it up!

I bet the lower rear gears really woke that car up! Good to hear you are rolling again!

I am not sure why some people have to act like such children and ruin things for other people. They obviously never learned manners...this was my WELCOME to the forum thread and the twit azz calls one of my projects garbage? Pretty low blow IMO. It is a poor excuse of a man to put down another man's hobby. I have noticed over the years that weak minded people mock what they do not understand. I may start another thread on the subject.

Sounds like you have similar luck to mine when it comes to clutches! Oh well, it will all be worth it soon! Then you will have to find a new project! Good luck with your Gremlin!

How are you making out with your project? Make any headway?

The A body cars were originally designed with the slant six in mind. The lighter engine works better than a heavier engine in many types of racing. When you double the car's hp and torque they will walk on a 340 car. The hemi version of the slant six was the best combination they ever made...well over 300 hp! Too bad they did not release them in North America!

Looks good Steve! You got a lot done! What is wrong with your headers? They look in good condition from the pics. I have done some mods to the collector on that type of header in the past to help them breath a bit better. I can tell you how if you want to use them still.
Good luck with your swap! Hopefully it won't rain on your project!
