The pistons ,rods, crank, springs, retainers, are here. As soon as all the parts are here he said he'll take the 416 apart and bore the block He is also truing and bushing the lifter bores.

Waiting for titanium valves and large Diameter Offset solid roller lifters. The rods and crank are supper light. I think the plastic bag weighs more then the retainers.

Boy that crank is a work of art! Like the conical sprAngs, too.
 
I can't wait to hear it with 2 1/4 zoomies . Should rev quick. We'll get it on the run stand soon. Its been a long time since I heard this engine. And now its getting some serious upgrades. .
 
Who polished that crank? Man that thing looks like a cutaway display piece. A shame to hide those jewels in a block.
 
How does he true up the lifter bores? Nobody in my area had a fixture to do it, so I carried my small block I'm building for my old Barracuda to a shop in VA that bored and bushed them on a CNC machine. That machine amazed me. I just stood there with my mouth hung open watching it work after he got the program set up!

If the answer is "BHJ" run!

If i may ask, What is wrong with the BHJ setup?

Lack of rigidity mostly. It's a decent setup if you just want to install bushings, but it CANNOT correct bore locations that are off. The BEST way is in one of the machining centers that probes the bore locations, and then rebores. But that's a crazy expensive machine that most shops dont have.

We had a block done on a CNC and the guy running it didn't have the block located correctly. When it was over the block was junk.. The BHJ fixture is a very good set up and is used by an actual machinist not programers. Any machine work is only as good as the machine but more important the machinist using it. Which must not be you. Unless you must mean run to the shop using the BHJ fixture. because once the fixture is installed using the correct tooling the bores can only be located at the correct position. I have heard and seen some of the disasters you have built. I wouldn't take advise from you.

There is a fixture in the cam tunnel and mounted to the top of the block. The boring tool is in a fixed position and cannot walk. You my friend do not know what you are talking about. Watch the video. You may learn something . My son does lifter bore truing in Pa.

I'm not talking about some guy on a cnc milling machine. I'm talking about a dedicated block machining center. Like I said the BHJ is good for just getting a bushing in the hole, but it is not good for locating bores out of spec. So tell me how would YOU know that the bores are correct when your done with your setup?
 
And I do know, I have used that exact setup, that's how I know there is deflection.

I see, it looks like the reamer is piloted off a fixture bar in the cam. Can you upgrade a block to a bigger diameter lifter?

Take a video of yours in your shop I would like to see it. I don't believe you ever had one. there is more deflection on an open ended reamer unless you destroyed your duel hardened sleeved fixtures from improper use. Or maybe you didn't read your operating instructions in your CRT book. C ritical R acing T heory.

I'll place a bet you sold it or threw it out. You'll have some excuse.
