One other thing on the 1967--68 grill I've seen 2 kinds as well where the outer trim that is alum i got 2 sets are stainless and one set is metal Not alum which modals did these come on i will re post this on a thread and what year did they stop putting protecto plates on car's and trucks amd didn't they put a few of theser engines in a few 1967--72 shortbed step side beds the 194 4cylender enging with 3 on the tree cus i know they put a lot of them in the 1960--1966 chevy step side and a few fleet sides with the 3 speed overdrives

[lbpd719]

never seen either of those (and have looked at a ton of these trucks)

got any pictures of these options??

[GREASEMONKEY72]

speed buzzer? mines a 72 and i dont have a low fuel light, just the brake and temp and ive never heard of a 4cyl in these trucks

[67CHIP72]

I have heard that the speed buzzer was an option only on the earlier models. I don't think they were available on 71-72, but I could be wrong.

[GREASEMONKEY72]

what exactly is a speed buzzer?

[67CHIP72]

I believe it was an adjustable meter on the speedometer that would buzz when you hit a certain speed to monitor gas milage.

[lbpd719]

i found a mention of it in my factory assembly manual. would be neatbto really see one

I've heard plenty of folks talk about the speed warning, and seen several for sale, but not the low fuel light. I'm sure someone who has one (speed warning) is about to chime in.

[1969 GMC]

If there was a 4 cyl, it wasn't in any GM literature. International Harvester did put a 4 banger in some of their light half ton trucks (iirc they were "slant 4" 1/2 of a V8 block), but I've never heard of any GM trucks having a 4 banger.

This is a loaded thread.I know the speedwarning did come with cruise control and I`ve seen 71/72s with it.Never seen or heard of low fuel indicator or 4 cyl.
The headlight bezels were black painted steel in 69/70 and swap with the bright aluminum 71/72s.67/68s had white painted steel or bright aluminum.

I've always thought that the vacuum gauge was pretty rare , what do you guys think ?

Only in the C40 and larger trucks.

[Spanky_Pete]

The 194 was the smallest of the inline sixes. I'm pretty sure they did not offer it in trucks after 1966.

[Longhorn Man]

the speed warning was 69 and older only
Never seen/heard of a fuel light, nothing in the GM lit, nothing in the assembly manuals
there was a diesel 4 cylinder... I think a perkins, but that was in P/30 chassis... not in C or K series trucks
The protecto plate was never installed on a vehicle, it's in the waranty booklet.

thank you Longhorn

The diesel engine that was offered in the P-30 Step Vans was the Detroit Diesel 3-53. It was a 3 cylinder 2 stroke diesel. There are rumors that a very few '67 GMC 3/4 tons had Toro-Flow diesels in them. As for the 4 cylinder, Chevy did make a 153 4 cylinder and it was used in the P-10 Step Van and the G-10 'Chevy Van' for a few years, but I have never seen one in a pickup.

thanks bob

Interesting. My 72 Skylark had a speed buzzer. It consisted of a movable needle on the speedo that would buzz once the speed was reached.

[Bob B.]

I am going to go out on a limb and say that if in fact no '67-'72 trucks were built with 153 4 cylinders or Toro-Flow diesels, I may have the rarest engine option, the GMC 351 V-6. I think the rarest combination would be the 4X4 panels.

[GREASEMONKEY72]

351 v6? i beleive its the 305 v6 and it is rare but not the rarest i dont think and it was only in GMC's

[burb71]

I had a friend in the Army he was at Fort Riley Ks, he bought an old olive drab 1972 C/20 from the Army.
The truck was orderd new in 1972 by the US Air Force, some of the options listed on the truck were the same as our civilian trucks, some options listed we did not know what they were.
But two things I do remember listed are PERMANENT COOLANT & PERMANENT BELTS & HOSES !!!

[Longhorn Man]

monkey... the GMC trucks, up till 68 I think... had an optional 351 V-6 in the CM/KM series trucks. Pretty uncommon.

[DJ72CHEVY]

how about a lwb stepside with lots of options. Only 3% of trucks made in our era were lwb stepsides. Would like to see more of lwb step trucks.

The 4 cylinder engine that GM made in the early 60s is just half a 283. The head is the same, and intake looks like half of a dual plane. They were available in the chevy II. I've seen one. Even rode in the car. It was a little under powered, but perfect for the highs school student that was learning to drive it.
Believe me the guys at the parts counter aren't going to have listed rebuild parts for it. You would have to let them know it's connection to its 8 cylinder brothers.
I can't imagine it would be worth much of anything in a pick-up

From Wikipedia:

The 153 in³ (2.5 L) 153 was a straight-4 version of the family and was only used by Chevrolet. This engine is entirely different from the later 151 in³ Iron Duke, but the two are often confused today. That name was never used for this engine when it was produced.

Applications:

1962-1969 Chevy II
1967-1971 Postal Jeep

I've seen a couple of these built up, My barber had a Model-T based street rod with a 153 with a header and some kind of home made 4bbl manifold. It ran pretty good in a really light car..
