Probably just my ridiculous incompetence, but the rocker arm saga just won't end. These new ones were terribly noise around idle and low speed. The noise seemed to subside at cruise rpm or higher. So I pulled the covers AGAIN (you have no idea how difficult that passenger side is to remove), I slapped in a piece of cardboard oil deflector, and fired it up. I initially noticed the pushrod having no room in the hole in the head and then all at once that rocker shifted to the left. You can see it in the picture. That was happening on at least two rockers on the passenger side which was where most of the noise was coming from. If I gave it a little throttle the rocker went where it belonged and stayed there. I can only assume that it was in the right place in the 60 miles I had driven the car. If the holes in the head were any bigger that rocker would have walked off of the valve stem. Nothing was hurt BTW.

Now I'm waiting on a reamer to arrive in the mail to finish up the spacers that I made to replace the springs. Geez.

Was it running when you took the pic? It is very bizzar that the springs didn't them. Maybe another problem?

They've made spacer for FE fords since the beginning of FE ford racing. It's always been an issue. The budget fix was two springs instead of one. My 400lbs of valve spring load doesn't help the issue I'm sure.

I found a new adjustable kingpin reamer that I bought for my '57 F100 but never used. Ironically it adjusts from 25/32" to 27/32". Sweeeeet! about an hour of work and I have spacers. And it sounds great now.

That's good work. I know what the RH clearance on that valve cover is like after putting the 472 in an '83 Malibu wagon. I cut out the corner of the evap box,reversed it and glassed it back in for more room.
Sure glad the rocker didn't move over far enough to come off the stem and push the retainer down,releasing the keepers. What a mess that would make!

For what it's worth, my MTS first edition adjustable full shaft rockers by Harland Sharp (from when MTS was a real company owned by Marty) actually measured 1.83 ratio. I ran them on the 514 Hi Port in the T with a solid flat tappet and just over .600 lift and had zero issues. Solid spacers are good!

Lost your thread for the truck. How are the chinna rockers working? Can I just bolt them in to a stock engine?

They work great. I just had the covers off yesterday. They actually the only rockers that I trust right now of the three set that I own. I didn't have oversize the pushrod holes in the heads. I did have to buy 10.350" pushrods because that cam is a small base circle regrind. I should have bought another set when they got down to $266 this past winter.

But can throw them on a stocker? Have customers that need rockers. And we all know after market ones don't exist.

Bolt on? Yes.

Pushrod length? Stock should work but I can’t confirm.
