Took the valve cover off and found a little problem.  Guess roller rockers are in order.

Better than a blown rod? Were these new , or reinstalled when you had the engine work done? Hopefully it's a quick and cheap fix. Good luck and watch the back. Big Al

 Rock On, Wayne!!! Thumbs Up
Be sure to check the lifter to make sure it hasn't come too far out of the bore, and....when yo get it back together, leave the valve cover off and start it...make SURE all of the rockers are getting oil on them. It might make a small oil mess, but it's better than a friggin tow bill. That rocker could have failed for several reasons....fatigue, not hardened properly, too much lift/coil bind, or....no oil/lube. Check that pushrod for straightness, and that the hole in the middle is open all the way thru.
 Hope it's that simple of a fix! But it would explain the noise....and the poof of smoke.

Al, this was a crate motor that was purchased about 4 yrs ago now.  Including this motor I've pulled 4 and put in 3.  This motor was put in for me buy someone that was, uh, not so good.  I don't blame him for this problem but you wouldn't believe some of the other boneheaded stuff.

I've got a set of valve covers in mind but WOWShocked are they pricey. Not sure if these will fit but they have tall ones as well.

Joel, with the way my back has been I'm going to send it out to have done.  Same place that did the alignment.  Sarge81 sent me to them and they're good.  Besides if they do something wrong I can always blame him!LOL

Dave, if you do buy a set of roller rocker arms, please do not buy rocker arms by Proform. They are Chinese junk! I made the mistake years ago and they almost cost me an engine after they disintegrated. Buy something decent like Crane Golds or something along those lines. 

My preference has been American made Harland-Sharp rocker arms. I've been putting them in "LS" engines with great success. Big cams and spinning the engines to 7000 rpms with no failures. Like most roller rockers you will pickup some valve train noise.

I had the same thing happen on my '73.  I did some more checking and found that the cam and entire valve train was pretty much wasted.  

Nice that it wasn't anything more serious!

John
