on the engine conversion. do you know where your truck was shipped to? i had that on my 66 cc ship to denver. i thought it might be a jet change in the carb due to high alitude ? does anybody have a 327 shipped to cailf. i was wondering if your oil cap is push on or twist on with a hose ?

According to another member more knowledgeable than myself, the "engine conversion" pertains to smog equipment adaptations on Fremont, CA built trucks depending upon where the truck was headed. Mine went to Enumclaw, WA.

do youknow what was on the smog truck? the denver truck i had looked like all the others i have had? well i hope we find out what it was . they had some weird stuff

Regarding the "Engine Conversion" , I have a '66 C10 with a 292 Built in Fremont and delivered to a California dealer. It does not have any "engine conversion" listed on the glove box, but does list "K19XM Exhaust Emission Eq" . The engine compartment is unmolested and still has the AIR pump on it.

Here's my '66 C10 Suburban

Re: 1966 service id label glovebox lets see them
 

So, does it make sense to say that if the Fremont, CA built trucks were delivered to CA dealers, then the smog equip was standard, but if shipped to other states that did not have smog requirements, then the "engine conversion" was essentially removing all smog stuff?

Re: 1966 service id label glovebox lets see them
 

I think it's true that back then ANY vehicle delivered to CA had extra emissions equipment, regardless of where it was built. The law didn't state HOW to meet the requirement, but AIR was the most common way. It seems backwards that AIR would be considered standard, and they would "remove" it from 90% of the vehicles.

So... I'm still not sure what Z20 Engine Conversion refers to. Comparing SPIDs the exact verbage for the same RPO is sometimes different from Plant to Plant and Year to Year. Was Z20 a Fremont-only option? This is gonna need more examples to figure out.

I have a 66 chevy truck c-20 shipped to cailf. No smog equip. Original truck . But does have closed engine pos. Vent option k24ed

Re: 1966 service id label glovebox lets see them
 

Regarding RPO Z20 Engine Conversion Equipment, this is in the 1966 Assembly Manual. It did several things-

(1) Threaded plugs were installed where the AIR tubes would go into the head
(2) Thermostat was replaced, presumably with a different opening temperature
(3) On L6 engines, the oil fill cap was replaced with a screw-on, non-vented one and a hole was plugged with a grommet
(4) It also concerns the distributor but pages A3 & A4 are missing

Attachment 1024287 Attachment 1024288

So -
• Apparently ’66 was the first year for this option
• It applied to all engines for CK10, 20, 30, and P10, L6 and V8 (???)
• K19 (Air Injection Reactor) and Z20 were mutually exclusive
• There’s no indication this was Fremont-only

There’s a lot left to understand here. Not sure why this was needed.

Re: 1966 service id label glovebox lets see them
 

so they have another type of conversion interesting thanks for the additional info
