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.

A little spray of oil on the roller cam/distributor gear. Saves the cam gear on a Buick 455. May do nothing on a Cadillac engine...………..but it makes me feel better.
The #1 main bearing on cadillac big blocks sprays oil via a slot thats formed when the bearings halves are installed in engine block. The oil sprays on the crankshaft slinger.

I put a couple of hundred miles on the car and now it’s coming apart again. I’m building long tube headers and a 1000+hp capable TH400 as we speak. Once the headers are done and sent to JetHot I will pull the engine to change the leaky-a$$ copper head gaskets that I reused and go ahead and check bearings while I’m at it. That’ll teach me........probably not.

Awesome build!!!!
Let me know how impressed you are when you are cruising then hammer it hard, and hold it through the down shift and back up into the up shift. Big Smiles on my 81 Trans Am!! Your car should be even more amazing. I have no doubt that you will be grinning even in your sleep after that. Hard work pays off well.
Congrates man.

That one was twisted wedge A460. I cut off factory flanges and mill it till it fits
.080 above port openings then I cut it in half down the middle for better port alignment.. the A460 twisted wedge aligns nicely with Cad500 ports with that one cut. Dissecting it further can improve that to Perfect. I've made other intakes from C460 after market for bbf. I make the flanges from .750 aluminum rectangular stock. Ive used thinner stock except it warps and then its lots of indicator time on milling machine.. I use templates made from gasket material layed out on intake ports of cylinder heads using small bullpen hammer gently like a silversmith. I mill the flanges to layout lines.. The C460 I cut off factory flanges and then set on flanges that are bolted to heads on engine block without intake gaskets on assembly stand. I mill the runners till their .080 above each port opening on flanges. Then I cut the manifold into 8 pieces and then start reassembling and tack welding till its assembled except for final welding.

Also I mill the intake port gasket face till its completely flat and 3.300 wide. It makes for full gasket seal and port roof raising to align with manifolds ports. This is on iron heads. I bought the Boogieman hi-rise intake from Mr. Potter when I bought the Boogieman heads. Here are some pictures of one the C460 intakes I fabricated to fit the Cad500. The C460 intake fabled to Cad500 is about same height as the aluminum bulldog intake. Also is picture of adjustable oil pressure device.

The aluminum stock I used was .625 thick and 3.250 wide. Not .750 although .750 would be preferred over .500. Good Luck.
