Now some fun stuff... Engine assembly.
You saw the dirty photos... This took some effort to get the block this clean for assembly.

My buddy Dereck Glesby the "muscle' for the job... and the brains... he is an aircraft field service mechanic by trade. He also has all of the trick engine assy and measuring tools to check clearances (rather than using plastigage).
No surprises aside from a little extra effort to set the thrust bearing clearance.

So... after we both misunderstood the Cloyes keyway instructions, I had to build a puller for the crank sprocket which we had installed incorrectly (couldn't wait the couple days to borrow one).

And the pistons are in!

Very light green hue on the cylinder walls is from the Total Seal "Quick Seat" powder for seating in the rings. I thought it couldn't hurt with this block only having been deglazed.

Dereck Degreed the Cam.
I always use Cloyes "Hex Adjust" chains in my engines. You can dial the cam in exactly. This is a Crane solid 396 425HP spec cam (I think its exactly the same specs as the 375HP). I Reused the cam that was in the engine as it all inspected perfectly and I had marked the original position for each of the lifters. Plus no break in drama or worry about a bad core. Some of Dereck's fancy tools !

The oil Pan was replaced with a stock style Moroso as the original was beaten beyond repair from bottoming out on gravel roads :haha:
A little clearancing was required on the Moroso baffling to clear the factory windage tray studs.

I also used a Moroso standard volume pump and pickup.

Are those 30 over 402? I took all three 854 blocks and punched them out to 427, years back you couldn't get 402 pistons (oversize).

Yes TRW 402 + 0.030" (4.155"). I would have to check the bills for date? but this engine was previously re-built and bored prior to my purchase in 97 and the car has been in storage since my purchase until starting into the restoration.

Using the tall intake just because I prefer the looks (I do have the original pancake manifold). Manifolds are ceramic coated. I went with non-smog, really not sure what was correct. For as long as I have known the car it did not have smog but... I've been told ALL L-78's were delivered with smog.:dunno:

Many of the 854 blocks can go to 427 specs...we owned one and it ran awesome.

Checking cylinder wall thickness is the first step...the 427 cubes are sweet :worship:

Big D's been a lot a help on the BIG PUSH to finish the car for the March 2023 local World of Wheels show. Here we are putting in the engine, trans.
Note we had also done the windshield.. I had previously picked all the dents, filed, sanded out and polished the reveal moldings. I was still waiting on the back glass... fingers crossed.

Those Gardner Exhaust systems sure do fit nice, don't they. Don't forget to install your inspection cover. Car is looking great, nice job.

Assembling the door panels.
Stripped off the old steel panel tops. Straightened out all the "teeth" of the panel joiners.
Pre fit the inner window sweeps to ensure the staple holes were all ready to go.
Some spray adhesive and lightly hammered the new panels onto the tops, then peened the claws with a small round headed punch.

Fender installation !!
I had measured and saved the fasteners and shim packs from final blocking for re-assembly. I also made some notes regarding exactly how I had assembled and final adjusted. After a small adjustment to measure and square up the cradle, they pretty much dropped right back into place.

No drama... Oh wait... I had been storing parts in the basement (garage is attached to house). Upon carrying the left fender up the stairs for the last of many times... I tripped on the last stair and literally Body Slammed into the ground fender and all. Well I could not even believe it but there was only one very small scuff which I'm almost certain will polish out and one chipped corner which hides under the windshield molding.

Luckiest day of my life !

----I used the same wire for several resto's, but I cut them a bit longer so it was easier for me to direct them thru the hole. Shortened them after partially folding them and then flattened them.....Bill S

I have seen staples put in tabs bent wheel side and engine side. Which is the correct way or is there one?

Hmmm... I know the mudflap and frame seal are correct but there were no remnants of the splash seals to check. I have a 68 which still has portions of the originals in place but it's away in storage.

oldstv 03-03-2023 06:15 PM

I have always wanted to know the answer to this question.

Your staples are backwards. Bent tab of the staples should be inside of the wheel well or engine compartment side. I have two original Novas and both have the staple tabs bent over on the inside. The bottom flap is correct.

Yes.. the engine is always covered except when we're working on something or taking photos !! Actually the entire car is also covered when not working on it.
Valve covers will be goin on shortly... did not want to take a chance scratching the Crane covers $$.
