Original 1200 Push Rod Length

Can someone tell me the factory push rod length for an original 1200 push rod in inches. Example 7.580 These are the push rods with the big aluminum ends.

This measurement is not the same as the stock 1600 push rod that we currently run and shorten to achieve max lift.

Thanks
Mike

Mike:

I grabbed 10 and they measured from shortest at 10.530" to longest at 10.655"

For some reason I thought they would all be the same length, but...

Hope this helps

Pushrod lengths are adjusted to compensate for cut-down cylinder barrels, and to optimize "area under the curve" valve train operation.

Mike:

You are welcome.

Got to thinking last night that the longest pushrod might have been for an application other than the Type 1 ( way back when) and got into my pile of "stuff". All those that were measured were within about .030" of each other- except the one odd one at 10.655
I could measure more if you think there is a need.

Mike, what do you mean, "with the big aluminum ends"? Do you mean steel ends? Good to see you're still working on stuff.

Hey Brian,

Its been a while. I hope things are going well for you. I thought about my post after I hit the send button. Yes, you are correct. The steel end. If my memory serves me there is only one end that has the steel part? I have not been racing the past few years but I am always busy working on vee stuff.

I have been side tracked the past three years restoring a 1969 Z/28 camaro that I bought in 1982. I started a rotisserie restoration in 2008 and finished it in July of 2010. I documented the whole process with about 3000 pictures. I disassembled the car in my garage and did all the work myself. The only thing I did not do is the body work. A good friend did that. I rebuilt the engine, transmission, differential and interior. Every nut and bolt is new, re-plated or re-finished in the correct color/texture. Check it out when you have a chance.

Maybe we'll see you at Sprints this summer or for sure at the Runoffs. Good luck with your 2011 racing season. Take care.
Mike

Hi Hal,

Thanks for the compliment. I put 1000 miles on it last summer going to cruise nights and shows. I am going to do the Hot Rod Power Tour this summer from Indy to Muskegon Michigan and then Detroit. I am going with a friend who just finished restoring a hemi cuda. It should be a great time.

Good luck with your racing this year.
Mike
