318 engine differences between CA and 49 state versions

It got worse, too. Many of you know I was stationed at NAS Miramar, San Diego. This was 70 clear to my discharge in 74 (electronics tech, I was in for 6)

Part of that time I had a part time job at the auto hobby shop on base. SOMEtime in those years, CA mandated RETROFIT smog devices on some older cars. There were several kits, likely the "best" of which was made by Carter. But one of the worst (don't remember the brand, was a simple kit, instructions, two vacuum caps, and carb adjusting screw add on green caps, and some green silicone.

I saw one of these on a 55 Chev, NOW LET'S JUST think about this a minute.......

So say it's 74, this poor abused mostly worn out 55 Chev is nearly 20 years old. The cooling system/ radiator is all clogged up with San Diego water, some of the worst there is (for lime and other minerals) so the engine runs HOT already

The purpose of this kit is to REMOVE AND DISCARD the vacuum advance hose, PLUG them permanently, and they LEAN the carb way down and CAP off the screws so that they cannot be adjusted, then slather bright green silicone all over them for a "seal." And you RETARD the initial timing, so now it REALLY runs hot.

First time I saw one of those messes I just stood there in disbelief.

I'm sure this achieved the desired result---killing off older car engines, thus getting them off the road.
