Citrus green 1970 z28 restoration thread

with the flywheel neutral balanced I guess I can send him that and the pressure plate and remove any imbalance from the pressure plate.

 

Yeah did a bunch of discussions with guys that still have 11:1 stock motors. Most run 93 premium and octane booster. The dynamic compression ratio is actually pretty low and I’ve got a connection for 100 octane nearby that’s not too outrageously priced. It’s just a local cruise and car show build so not planning long range trips. A 55 gal drum will last me awhile

 

Yeah, I’m 5 mins from our small regional airport but in commifornia they likely won't sell it to you in a can or pump it into a car.

 

It is illegal to fuel an on road vehicle with road exempt fuel in california (where we both live). I haven’t broached the subject with the fuel distributor at my local airport but it may be possible to get cans or drums filled. I have a connection for CARB legal 100 octane not much farther away so plan to just go this way.

 

I’m being honest with you. I was a senior environmental compliance assurance manager for the Largest O&G company in calif so I’m well versed in CARB, BAAQMD, and other state and federal regulations. Many rules specifically include a component whereby the person(s) or companies they represent aid (knowingly or not) aid in the commission of the violation they are liable for as well. I might be able to get gas in a can or drum if I tell them it’s for an aircraft but they may require me to provide tail number to do so and fuel sales are required to logged by the FAA ( I learned that working on an avgas incident years ago where it was contaminated by #2 diesel). I Can’t remember if av gas is dyed (it likely is) so easy to tell. I can buy CARB approved 100 octane sonoco 6 miles from me for $9 a gallon and they can pump to fill the tank so that’s the way I’m going.

 

Been trying to decide how to finish the intake and valve covers. The recommended way is to brass brush burnish the valve covers then dip them in ppg dx501 to reskin them. This is a chromic acid solution the brightens the metal and seals the surface to prevent staining from oil or grease. There is also a fairly new (to the US) process called vapor blasting which is essentially a water slurry of glass beads which brings finishes back to an as cast brightness. There’s a local guy here that I used and had all parts done very reasonably. Here’s some before and after. The valvecovers before picture is after burnishing with a brass brush.

I’m planning to do the reskinning in the next few days so if anyone has any suggestions on best way to apply. I bought enough to make 1/2 gal of solution so soaking the manifold likely wont work. (Update): I was able to apply with a spray bottle which evenly coated all surfaces and saved a ton of chemical vs. dipping.
