What kind of Loctite is this then or are those not the case nuts?

Thanks for bringing up the question of the case bolts. I don't what to confuse anyone its hard to note every detail. I am not trying to make a how to manual I am trying to get out as much info as possible. Any input would be great or different ideas would be great. If I don't have an answer I will call Walt at Comp and find it.

I probably should have spent a little more time on the different products that were used on my engine build.

Better late than never.

I use the ultra slick on all the bearing surfaces
rocker assembly
and the rod on the cam followers.

Here is a little info on it.

Permatex 81950 Ultra Slick Engine Assembly Lube

Proper lubrication of metal mating surfaces is essential prior to starting a new or rebuilt engine. Ultra Slick adheres to component surfaces to prevent scuffing and galling during initial start-up. This high quality formulation meets or exceeds OEM performance specs for engine assembly lubricants.

Permatex 81950 Ultra Slick Engine Assembly Lube Features:
• Container Size: 4 oz. bottle, display boxed
• Part #: 81950


U.S. high performance assembly lube is more of a paste

It was used on the cam lobes and cam bearing surface.
Also on the flat area on the cam follower that rides on the cam. The thicker lube allows more of a coating for break in.


The Curil T is used as a sealer.
This was used on all rubber o-ring or seals

Here is some info,

Curil T
The non-curing, high-temperature resistant,
synthetic resin-based, universal sealing compound
for permanently hot service conditions.
Temperature stability: -40°C to +250°C.


Loctite 574 was used to seal the two halves of the case together

Here is some info.

LOCTITE® 574™ seals close fitting joints between rigid metal
faces and flanges. The product cures when confined in the
absence of air between close fitting metal surfaces. Provides
resistance to low pressures immediately after assembly of
flanges. Typically used as a form-in-place gasket on rigid
flanged connections, e.g. gearbox and engine casings, etc.
The thixotropic nature of LOCTITE® 574™ reduces the
migration of liquid product after application to the substrate.

I hope this helps please let me know if you need more info
Thanks Jerry

Installing the # 4 bearing in the timing cover or the 3rd piece of the case.

(Earlier I referred to the #4 bearing on the flywheel end of the crank. I miss spoke and had Rick Becker change it to the #1 bearing. )

Thanks Rick

Heat up timing cover at 175 deg for about 15 minutes
Place bearing in freezer for 5 minutes
Install set screw in timing cover just enough to line up bearing should not touch bearing
Line up set screw slot in bearing and set screw and press in bearing.
Tighten set screw.

I had the oil bypass installed also. The idea is to take all the oil, filter and or cool it and then send it back into the case.

Basically install a plug in the timing cover where the oil returns to the case.
Install a threaded nipple in the oil cover.
Drill and install treads in the timing cover inline of oil supply

























Here is a diagram of normal and bypass

Little Tube?

Hi Jerry,

Great Job! Excellent details!

One question, what is the thin tube in your right hand with the little red gasket in your left hand and where does it go?

Thanks,

Steve

Hi Jerry, nice work, just wondered what you have done about fitting the distributor drive and getting the timing of it right.
Mine was in the 3rd piece of the case when fitted to the engine.

Cheers, Nick.

Using Loctite on the case nuts is really unusual...

Installing distributor gear and distributor.

Set Piston #1 TDC

Install washer with a dab of Assembly lube use a screw driver to guide washer in place. The lube is to keep it from moving around.

install gear carefully so when set in place the grove is offset to the back of the engine. (note with the fuel pump out you can reach the bottom of the gear to help align).

Install distributor and check that the rotor is at the notch for #1 spark plug wire.

Installing pistons, cylinders and heads

before you can install P/Cs you need to determine deck height between piston and cylinder. Note compression and deck height should be determined by the piston manufacture. Pistons should have spec sheet to determine proper clearance.

I used JE light weight racing pistons with a 60 to 65 thousands or 1.25 to 1.5 mm clearance at 9.25 compression.

Rotate engine on its side.We install one set of P/C with a .5mm shim as a test fit. We used hallow core solder 2 pieces 1" long at the out edge of piston installed head and rotated crank. Check clearance. We ended up using a 1 mm shim

Install P/Cs push rod tubes and heads torque at 10 than 25 lbs

That's it we're at a long block baby
