I got the Cam Locked in at Intake ℄101°... First Time I installed it at 0° on the multiple Keyway Crank Sprocket that came with the Rollmaster Timing Set, It measured out at ℄98°  so I set it to the -2° on the crank sprocket (which must be 4° camshaft Degrees)..  anyway it's all worked out.  Recommended intake ℄ was 100°-102° so it's just about right.

Also got lots of little things completed and the Cam stop Built, using an old Rocker adjustment screw as well as some 3/8"-24 Fine nuts from the hardware bin.

Time to Finish the Tins, Install the Rear Main Seal, Lots of Gasketing, Oil, Water Pump,  Some revisiting on the oil Pan for dipstick and Other small issues , then seal it up move on to setting the Rockers up, Intake, Carb, Fuel Line, Headers etc.  I might throw an extension on the vent tube on the fuel pump to keep the area behind the fuel pump less oily too. It will probably throw oil out everywhere if I do not do that with the corners that I am anticipating.

I will also be putting a mock up head back on that mock up block to hang the headers and build an exhaust before I drop the actual engine in the car. - Fire up the Argon Bottle for Some Stainless Mig and Tig work...

That is one serious oil pan!

In reply to MadScientistMatt :

Well thanks, I am still not done with it yet, but getting close.  You can't go to stefs, Moroso, Canton, etc and buy a road race pan for a slant 6. Sooooo. You gotta make one. It's not pretty but I hope it should work fine.

I finally Finished up the Oil Pan - Added Some More Baffles at the Front and Back to Separate the Sump from the Area Just under the spinning crank.   I also added a windage Screen.. It's Held in with 4 Button head screws that I loctited in place. Also Added a provision for the Dipstick (thanks MadScientistMatt)

I put the mock up block back in and Hung an old Head on the block along with the bell housing, Z, Bar, Clutch Fork and Headers. Began mocking up the exhaust.  Waiting for my 2nd Argon regulator to arrive so I can weld it correctly with some back purge argon inside the tube.

The Pan is finally done - whatta beast it was to make that part..

It actually looks somewhat normal with the fresh paint on there.

Windage Screen Should help somewhat.

"glued" down the Crank Scraper and the Oil Pan spacer on the other side.

Mock up Block back in to begin the Exhaust Primary Tube mockups... The Front tubes will take a bit of time.


Slice and dice.

Backpurging is recommended for a reason..so is using a TIG machine that has a foot pedal and is not a lift start

Waiting on some parts before I can button up the oil pan and Timing Cover..

In the Meantime The Rocker shaft shim packs came in.. 
It's nice that the old MoPar Engineers were too lazy to make the stock rocker shaft any different from the B-RB/ A/LA Hemi Blocks The Shaft Diameters are all the same. (thanks Willem Weertman and Tom Hoover)
So I was futzing with setting the side play on the rockers - Almost done - Some are too tight when the shaft was torqued down.. Need to remove 0.015" spacers on a few pairs.

Still waiting on adjuster screws from Smith Brothers too.

This engine is using some of the recycled top end parts from Ruster - Push Rods - and 1.5 (I think ) Roller Rockers that came from the Mike Jeffery Cache of slant 6 speed parts.

I still have yet to see if all of this fits under a stock Valve cover without hitting stuff.. It's not a High Lift cam so hopefully I don't have the rocker screws hitting baffles and other parts in the rocker cover.

Happy Hemi Day.. I don't have one of those so I am celebrating by getting some stuff done on Grüne Hölle.


I got the ARP Cam bolt Installed..it's dimpled in the middle for use with the Ball End Rocker screw.
Got the Timing Cover bolted and sealed, Got the Oil Pan installed. Got the head installed,torqued and set the Cold Lash on the Lifters in prep for the first start.

My Backpurging Equipment arrived... Now I can attempt make better / nicer / more structurally sound welds in the Stainless tubing for the exhaust.  I also got to doing some tube fitting as well.

That rocker swap is very cool - what ratio / specs are these arms?

Not too sure.. I believe they are 1.5's but i would have to measure to be sure.

 

When I see skookum slant parts used for sale I buy 'em ... cause you know its expensive to get the stuff made as a one off....and there's not really a go to performance slant 6 supplier in this hemisphere.

Getting some of the Exhaust Routing Figured out:

I was able to get some more exhaust work done.

Got my 2 down Pipes (for lack of a better term) (the pipe from the header flange to the Y collector before the muffler) Completely Mocked up and one fully welded.

My next task will be to fully weld the other down pipe and then work back from the wye collector and build the intermediate pipe and tail pipe.

Fitting Pipes - Blue Masking tape is helpful when working with non magnetic stainless for fit and making proper witness / alignment / clocking marks.

Lots of Funky Bends and angles here.  Kinda Felt Like I was building a header.

Breaking out the Hot Glue Gun..

Not Perfect, but Getting better' Cept for where I burned holes and had to use a bunch of filler to fix it. Backpurging = easier TIG Beads on stainless..  YAY!

One done.. one to finish weld.

I Got the Tailpipe Built and Finish welded, so Now the exhaust is mostly Done... Still have to locate / Drill / Weld The bung for the O2 Sensor, Add / Weld on One more header collector Tab, and Fit the Burns Muffler when It arrives.. For Now I just have a piece of aluminized Tail pipe in place of the muffler.

Pictures of the Progress:
Tailpipe complete with exhaust tip / turndown:

Hopefully  when everything is installed It won't Bang against Frame or Gas Tank..

Speaking from experience here: You may want to put some heat shielding on the gas tank and use exhaust wrap on the near section of tail pipe. I ran into problems of pressurizing the tank to the point of pushing gas out the vent last year when on track in the heat. Normal driving and track at cooler temps wasn't pushing gas out...but i'm sure it wasn't helping either.

In reply to asphalt_gundam :

Sounds Good Thanks for the suggestion.

I never had an issue with the old engine and tailpipe in this area, as it did get hot, was super restrictive, and drove it alot.  But I do appericate your insight and will keep an eye on it.
