Finally got my rods back from Ollies. They did a nice job balancing them so that each rod is within 1/2 gram of each other. They expedited the job with one day turn around in their shop. UPS messed up on the return shipping, so it took 10 days for the package to get to me. I installed the rods on the crank with ARP rod bolts using my micrometer to set the rod bolt stretch. Then I fit the crank in the case. I'll make up a new set of tools to hold the rods and chains up while mating the case halves. Should be ready to seal it up early next week.

The engine looks amazing. Beautiful work ! Like the rubber band mechanism, that gets it done. No flopping about. Look forward to more.

Yeah...The rubber bands keep the rods from getting caught on the spigot bores and allow the engine to be rotated with no hang ups.

I installed the flywheel and crank pulley today. Being new to the 914 world, I am wondering where to make the ignition timing and TDC marks. I understand that the 914-6 had the timing marks on the flywheel in line with the crank pulley as there is no visual access to the crank pulley when the engine is installed. I am guessing that I should paint a fine white line on the edge of the flywheel at the case parting line when the same mark is lined up with the case parting line at the crank. One for TDC, one for my timing mark and one each at TDC for the other cylinders to enable setting the valve lash.

Am I on the right track?

After doing a little research on this timing topic, I concluded that I will mark the flywheel at TDC for each cylinder with a white paint marker and at my timing location with a yellow paint marker. I am hoping that the access panel in my firewall will allow me to see the crank pully and easily access the distributor, making the flywheel marking redundant.

Ok dumb question as I have no personal experience with anything over a 2.7 engine in a 914-6 what pressure plate and transmission are you using with that flywheel? Every 6 conversion I have dealt with is a cup style flywheel and what you have would not work.

Hi Ben

I am using a Kennedy Engineering 228 mm stage 2 clutch package. It allows conversion of the 915 9 bolt flywheel to the 901 type clutch and pressure plate.

Tom you're on the right track.
Use the pulley marks as your guide on the flywheel. I don't know if you'll have proper flat surfaces to mark with those KEP parts.
You're using a conventional dizzy ? If you adjust the timing through the access hole
in the bulkhead be very careful ! Fans/fanbelts have no mercy.
It's awkward but very convenient.

Thanks Rory

I am using a JB Racing twin plug dizzy. I think if I mark both the flywheel and the KEP ring gear adapter, I will have something that will show up with my timing light.

Today I did the deck height check using both the vernier at TDC and the solder method. I did the check on cylinders #1 and #4. Ollie's had supplied 0.5 mm base gaskets based on their resizing of the case. Using these gaskets, deck height as measured on the crushed solder came out at 1.2-1.3 mm. That along with my measured combustion chamber and piston dome volumes results in a 10.0:1 compression ratio. Right on target so I will move forward on the assembly.

Continuing to move forward on the engine build. Heads and cam towers are now installed, and the cams test fitted.

I applied JB Weld to seal the chain rail and tensioner posts on the backside of the chain boxes. I also used the JB Weld to seal the case oil line webbing on the RHS of the case behind the oil cooler.

Here is my homemade setup for the sprocket alignment. Works well. Very accurate and repeatable. I ended up with (3) shims per side. Next up will be the cam timing.

I did the cam timing yesterday. DC-60 cams with a spec of 4.8-5.2 mm at overlap. I set them at 5.25 mm.
