I had a feeling it was a BB being they have two different size push-rods. You may also want to check for any bent rocker studs.
I recommend to drop the pan to check for metal chips in case some are small enough to get pulled past the oil pump intake screen.

Ill see how it goes.  No plan of dropping anything at this point.  If I do drop the pan the engine will come out first.  


I had a feeling you were just venting as I think you are about as savvy a Chev guy as they come. I also know you already had thought of all I suggested too. Some of those P-Rods have one end hardened for the guide plates. May have been installed wrong? I had a P-Rod shatter on the lifter end once. Usually, gasoline or geometry causes bent P-rods. I have also seen some Sm. Blocks P-rods go through the rocker. Are the P-Rods 5/16, 3/8 or 7/16 in.?


3/8" and case hardened..

Already thought of all that as well.  Just irritated and wanting to vent.  lol  I will figure it out just not what I wanted to do on a fresh (8 year old built) engine.. Roll Eyes

Engine was broken in back then and had sat unstarted since 2006.  I would turn it over from time to time by hand.  Engine sounded fine when I fired it for the first time since and just a few weeks ago I noticed rocker noise and adjusted them then.  Now I know why there was noise the first time.  Its just odd it was only the exhaust and no intakes...

FYI the pushrods that were pulled out are 1010 mild steel.  Comp Magnum roller tip rocker.  Cam I am guessing by ear is either a .520 or .570ish lift cam (I am leaning to the more .570ish lift due to the radical sound).  Hyd flat tappet (that I do know).

Odd thing is the lifter side of the pushrod is fine.  Just the rocker side is damaged.  Almost like it was starving for oil.  Right now I want to make sure the geometry is correct and look for coil bind (which I do not think it has).

As far as runtime...  Other than break-in it has run maybe an hour if that.


No smoke and plugs look good except for the ones that had the issue which were a little fat but nothing major.

Last Friday I had the exhaust installed on the car which took all day but thats wasnt a big deal. Car sounded great (sorry no video yet) so I pulled it off the trailer and into the garage. Saturday morning I started having issues with idle and backfiring through the carb and dying. Figured it was just where it had been sitting for so long so I took it for a short ride around the neighborhood. As I am pulling back into the drive it acts like it is flooding and dies. Get it started back and pull into the garage, get out and pop the hood to rocker arm noise. I pull the valve cover and this is what I find. 4 of the 8 exhaust pushrods are destroyed on the rocker arm side. 3 on pass bank and 1 on drivers. I did not build this engine and what little I know about it doesnt give the enough info to determine the cause. So first things first is to check pushrod length and go from there. I really dont want to pull the engine out before I have a chance to drive it at least 100 miles.. Awesome luck dont you think...

Haven't seen you post for a while Darrell ,always welcome your " 2 cents "  Smiley

Remember Turbo Blue ?  20 years ago a station used to carry it in town...and 2 on the way to the track.
It will be happy days for him when he's down to reading plugs for heat range selection.Pretty sure somewhere
buried in the posts are factory recomendations for a base line.Colder plugs for towing.(racing) Don't know what year they stopped , but it was listed in the owners's manual. 64 I know for certain.



Thanks.  Ive been a little busy with work and trying to finish up the 67.  The most fun you can have is reading plugs and deciding what timing to run and adjusting jetting the carb.  Good times (racing).  Turbo Blue..  Havent heard that in a while.  I run Renegade Pro-110

Are heads set up for unleaded? If you mean with hardened seats, Yes.
Cropper sells racing fuel by the drum
I will experiment with fuel mixtures, but have no intention of de-tuneing Wink
Here is a link to Cropper's : https://www.facebook.com/pages/Cropper-Racing-Engines/178083025573562
Replies on FB site reference to a guy named Weasel. I worked with him-Weasel Rhoades

Just remember when running higher octane like 108, 110 or 112 or higher you will need to add a few degrees of timing to allow for a better burn of the fuel along with running a hotter plug.  Example:  If the cam calls out for 6 degrees and your total is 34; go up to 36 or so and see how the plug looks.  Im sure you already know this but just felt like chiming in.   Tongue

I usually run 110 and 92 or 3 ethanol free 50-50 and run a few degrees more timing.  But I run a slightly colder plug too. Still experimenting due to very little run time which might change over the weekend..

I will get at least one this go around.

Congrats buddy.  Im sure it will be beautiful (minus it being HO) once again.. Grin

Looks to be around the 3rd week of Sept.  If I did the math correctly.  Whats the build date on the tag?

Looks really good!

Didn't realize these were flash chromed.  If that's the case you could always have them hard chromed again.  Here are some pieces I polished this past weekend.

Here is some good reading on polishing stainless

Yes you can "burn" the stainless.  I have gotten several pieces extremely hot and haven't burned a piece.  What cutting compound are you using?  Stainless isn't like chrome.  I have even sanded areas after working dents out and going from 80-1200 grit then on to polishing
434  Camaro Research Group Discussion / Restoration / Re: rain drip bright molding on: April 07, 2014, 02:29:51 PM
All 3 years are the same.  You can polish them out if you so desired.  It is a lot easier to polish them if they are on a car before it is painted.  If there are dings or scratches in them then those will need to be taken care of before polishing obviously.  No info on repos.  I have polished all my original windshield and back glass trim and plan on doing the drip rail moldings at a later date.
