Looks great! Progress! Very nice to see a strut in that jamb; I won't have to get custom-fitted doors.eye popping smiley

I've been curious why the jambs rust in that area where the jamb blends with the sill at the top/front of the rockers. Did you happen to capture any pics while the metal was out? Was it packed with dirt? If so, how does it get in there?

The bracing was added as soon as this lovely surprise came to surface.

The gift that keeps on giving! Lol

I did find both areas full of foam installed at the factory

Beginning to trim out the Swiss cheese for a plan of attack.

Rear floor cut from donor, trimmed to fit, and tack welded in place. Plan is to plug weld across the front and butt weld around the sides and back.

Next will be deciding on sectioning in patches into the drivers floor, or grafting in the rest of the pan...

I’d say the explains it. Probably that was put in there to inhibit rust. Lol

Craig, will you be installing HandS wheels to this car when done?

Yes! I purchased a set of original Hands wheels from Chris L. That will be the only deviation from the "as owned in '71" configuration. I also purchased a set of three-prong wire wheel covers (From Mr.Lakewood/65Guy) so I can also run the car in it's exact 1971 livery.

Awesome - That is going to be one sharp looking vert when done. Can't wait!

Just curious for my research, can you describe the cast-in markings on the back of your HandS wheels? You can PM that if it's too off topic.

While Cody has been wearing out his welder fixing the floor, I have not been remiss in my duties. I've been gathering parts for the car and engine. I started building last week. Chris Langley provided smileys with beer a correct dated-code RB block that had been in storage since the beginning of time. It needed a good clean and a row of cylinder head studs.

Cleaning consisted of light sand blasting (it was stained and served as a mud-wasp lodge), followed by a commercial parts washer, followed by high-pressure steam clean. I think it's clean now.grinning smiley

After installing replacement studs, the first order of business was to test each one for strong threads. (First Picture)

Years ago, Tom Zimmerman sold me a very nice nitrided 140/180 crank. I gave it a light polish (Kerosene and 600 grit wet/dry). (Second Picture)

Once polished, I proceeded with plastigage clearance measurement on each rod bearing. (Picture Three)

Edit: Sorry about the sideways pictures. I tried rotating without success.

Once the rod clearances checked out, I trial-fit the crankcase halves to plastigage the main bearings. (Picture One)

That all checked out so it was off the races to actually assemble the crankcases for real. I purchased an Isky 280 cam with a Ray Sedman adjustable timing gear from Jonathon Knapp and I'm really excited to see how that all works. One surprise there was the need to chamfer the cases right behind the cam gear. Without the chamfer the cases couldn't get far enough into the cam gear's hub so the thrust washer wouldn't slide into the upper case half.

With the cases together it was time to slip in the 1/3/5 piston/barrel assemblies and "torque 'em up!" (Picture Two)

Invert engine and on went 2/4/6. (Picture Three)

Tomorrow: Cylinder heads and their story.smiling bouncing smiley

Oh, one more thing: If you haven't used plastigage, it's a thin wax rod you use to measure bearing clearance. Bolt the parts together with the plastigage rod in the gap and it gets squished.

Measure the width of the squished Plastigage rod to know the bearing clearance.

Our rod bearings are supposed to be between .0007" and .0027". This one was my worst at a tad tighter than .0020"; nicely within specs.

Today's progress report:

Picture One: Flattened the head gasket registers

Picture Two: I prefer soaking paper gaskets in oil rather than using sealant.

Picture Three: Set the cylinder heads in place (one nut). I'll install for real tomorrow.

Sorry about the sideways pictures. They're still sideways despite rotating them before posting. I'm going to stop using my cellphone and go back to the camera!hot smiley

Degreeing the cam was, for the first time ever, fun! smileys with beer All thanks to Ray Sedman's amazing adjustable cam gear. With this gear, you don't have to assemble the crankcase multiple times and you don't have to use split keys to adjust timing.

Just set the timing mark and rotate the cam until the lift is .050" and it seems to be done.

I'm going to start a separate thread on use of the gear and cam specs because I still have questions. Inquiring mind plus I'm not totally confident because the adjustment is near the end of the slot.

Just think how easy it will be to TUNE the Cam if you don't like it's power curve!

Looks like one tooth over and you'd have equal adjustability!

Center section of rear seat riser welded in!

For some reason, someone had badly sliced up the upper rockers for the rear window drains we are guessing. Rockers fixed and ready for the outsides of the seat riser fitted and installed. At this time, i also heated and removed the rear trailing arm toe bolts, due to easy access. Cleaned all threads with tap and die, coated in never seize and reinstalled

Right rear toe bolts were non-cooperative. Heating and waxing several times usually works for me, but this is one of the rare times it didnt. Off to the donor floor for more replacements...

Passenger front floor patches rwmoved from donor floor, small amounts of rust repaired, fitted and butt welded into their new home.
