1966 Corvette L72 Light Refresh

Nothing more than a small PSA. Perhaps a bunch of you guys already do this. I blew out the frame rails in the 66 today. This is a byproduct of about an hour. Remarkable what sits inside the frame rails.

That is very minimal for a 57 yr old car. Looks like mice have been in there at some point.
Is there such a tool as a refillable pressure container with a hose and conical nozzle to spray BoeShield in there ?
I cut the right rocker off the '70 Chevelle and got a 2 lb coffee can full of rust, dirt and mouse nest "stuff" ...

Really ….. you just blew out 59 years of Original particles from various roadways this Corvette traveled

Have a nice chilly day Tim.

BTW, great thorough BaT auction on the Red Roadster!

In the 80’s I worked for the Canadian Co. Rust-Check which is the Automotive Rust-proofing derivative of Boeshield. What we used to apply the product then was approximate 4-8’ pieces of transmission lines w/ airline fittings and product feed on lead end and other ends squeezed/brazed closed but w/ a few hacksaw slits near the tips allowing product to blast out about 180 degrees while under compressed air pressure, lead ends were marked so you knew which direction the spray was pointing to avoid direct soaking insides of door panels etc. Drilling holes big enough for the tubes to fit through, you’d push the tubes in and out of doors/fenders/quarter panels/truck box sides etc while squeezing the trigger and the product would fan out of the slits which resulted in spectacular coverage of areas you’d never gain access to otherwise. Under pressure, product would often blow out the complete opposite side of the vehicle also removing a door panel or inserting a borescope to view coverage success, it was amazing how well the process worked. Also important was drilling A-Pillars near the base of the windshields but above the welds that a lot of cars had then as many A-Pillars were full of water, which you’d of course allow to drain before hitting w/ the product. One more thing, the plastic plugs you’d insert into the drilled holes after process completion were soaked in product so bare hole edges had product on them too.
Boeshield and Rust Check are formulas w/ synthetic oil as their carrier which displaces moisture and reacts w/ metals, rust which is also a chemical reaction, cannot happen at the same time. Boeing was experiencing reactions between the aluminum skins and rivets which would loosen rivets similar to when something freezes/expands, Boeshield reacting stops the metal reactions…same idea w/ automobiles and steel materials using Rust Check.
Lastly, there’s other copy-cat products out there, some very well marketed too but they don't have the same recipe and chemical reactions, just oil doing their rustproofing. Tar products do little good also often block drains, they also electronic devices are more to pretend they’re doing something while what they’re really selling you is a warranty.
Sorry this got so long, I started typing to mention the tranny lines for product application.

Now that MCACN is behind me, I can get busy on some tedious little items. I blasted the exhaust manifolds, dusted in some paint on the top (where some remains previously existed) and then soaked the rest of the manifold. I suspect this will burn in nicely and play the part, albeit a little cleaner than previous.


The shifter boot has seen it's better days.


I had an NOS unit in my stash


A little gentle heat would make the boot take it's proper shape



While waiting for the trailering arms to come back, I cleaned up the spare tire carrier and the applicable bolts. Some time in Evaporust and the ultrasonic cleaner helped things along.



This one that has certainly seen it's better days. Nonetheless, clean it up and wait for a better unit to find it's way to me.




Lastly, I got word the engine just came off the dyno. The smoking gun(s) on the vibration issue consisted of.....
1. The crank required 100 grams of heavy metal to be added
2. None of the pistons had been balanced nor were the rods

I'll post more about the engine when I get it back to the shop. I'm told 460hp is the peak number. That is with dyno headers and the original 3247 Holley. Historically, the dyno at AMS is stingy. Furthermore, Steve is not one to spin an original numbers engine hard unless instructed to do so. More to come!

It was certainly enjoyable BS'n Bill. I was busy over the show weekend judging 67 Corvette's . When I finally got finished up, I spent the rest of the time catching up with so many friends I have made in this hobby. I basically never saw the show. While the cars are great, the people are priceless
