Looks like a repo tag to me...  But would like a better straight on photo.

I always do the break-in and then upon shut off adjust the valves again and drain the oil.  That is a pretty good little cam you used.  What is your complete setup?  Do you plan to put it on a dyno?

Solid lifter.


I would say .02 tighter cause when it warms up the lash will get looser.

What happens to steel when it is heated?

It expands.  Which will close the gap.  So if the cam card calls for 0.016" hot then you add 0.002" to that number for a cold setting.  Set the lash to 0.018".......


Aluminum heads are a different story.  You would subtract 0.006" on the hot lash spec.  If its an aluminum block & heads you would subtract 0.012"

Not really.  This company you have either oven cured or air.  I went with air.  Just spray with a paint gun and let it air cure.  Here is the gun I used and of course the Cerakote.


Great little gun for what I use it for.  Put a regulator on it and run it at 30psi and you should get the same results I did.  I would recommend to run some Paint Thinner through the gun first but other than that once you get the pressure set (just remember to check it often due to its sensitivity) and spray away.  I have always had this done on motors I built in the past (newer LS engines) but never did it myself just sent them out and had another company do it. 

Being that my bearing tolerance is at 0.003" on all the mains this coating will add 0.001" roughly so I will be where I want to be on tolerances.  Next once I install new cam bearings and finish prepping the block and slick coating & thermal coating the pistons Ill do the rod bearings as well.  Once the engine is broken in on the motor stand I am going to ceramic coat the headers with the high temp coating in the titanium color.  (see last pic)

Finally got my new intake gaskets in and got the ports scribbed. Also got the main bearings gauged and then shot them with Cerakote Slick Coat.

After Cerakote Coating:

So .018?

Yes. That way when it is hot it'll be 0.016"
248  Camaro Research Group Discussion / Maintenance / Re: intake on: June 07, 2014, 06:12:05 PM
It's not needed with the rings but it won't hurt either.
249  Camaro Research Group Discussion / Maintenance / Re: valve adj on: June 07, 2014, 05:49:17 PM
Sorry I started my post a hour ago and got side tracked.  Your thread you posted is basically the same as my post.
250  Camaro Research Group Discussion / Maintenance / Re: valve adj on: June 07, 2014, 05:42:49 PM
I have always used the EOIC.

Exhaust valve begins to Open adjust the intake.

Intake valve begins to Close adjust the exhaust.

Yes the 0.016" is hot..  Add 0.002" for thermal expansion.

Very odd you are getting a lean and rich condition at the same time.  Pull the ignition module and have it tested.  Also like Hawk said double & triple check the firing order.  Also double check you dont have the dizzy 180* out..  These are just a couple of the first things I would look at.

Is this car still around?

Just for comparison.
